Oh, oh. or maybe oh sh#*$%#@. I'm reading the thread I posted and
want to apologize for subjecting the Optibikers forum members to some
of the more colorful opinions used by the mountain bike forum
posters. This entire passage is a Quote.

she's a little heavy, but once you get to know her, she can be quite
fun.
nice comparison

I'm in that exactly point. I made some tests with weight added to my
current rear hub, I've checked and thought over all aspects of chain
tension in my fs case, I've checked best available deals.
I still wonder if I will be totaly happy with it but somehow I know I
have to see for myself." End Quote

Had to laugh tonight after coming back from a dusk ride . I do a
circuit around 20 miles which includes some really cool downhill
flyers . well tonight i was on my intense 6.6 bike with normal road
helmet on . This route I have ridden for years and know every pothole
crater drop you name it . i stopped at a gate for a breather and this
old guy leaning on his stick , struck up a conversation . he commented
that he could see me with my lights on from around 5 miles away on
what we call the shoulder of kinder and could pretty much tell how
fast i was going. He then began to tell me about a local folklore that
had sprung up . He stands by the gates nearly every night at dusk
watching over the fields and valleys. Now he says it took you 20 mins
to do that section from coming over the 1st ridge and climbing the
last 2 ridges. The black phantom who comes through here , Black bike ,
alien shaped helmet , black clothes
does it in 7 mins . 1st time i saw him was last winter he is moving
that fast , it sounds like a swarm of bees are following him . You
could learn a lot from him he added , I told the wife thats not
humanly possible.
Wonder who that is ? Did not want to spoil his tale, plus he tells
every biker he meets .

For me its a really nice option . all my other bikes have 27 gears and
3 rings and to give you an example . After my ride last night on my
6.6 lost the high gears due to stretch , rocks , etc . In the garage
10mins fettling and cleaning , quick spin , all ok off for a shower .
Rohloff quite a few thousand miles , not sure what it looks like.
Precise everytime. What i disliked about the 9 speed was the limited
ratios thats why bikes have 22 or 27 gears and the horrible crunching
you used to get every now and then , which is a symptom of rear mech
and high torque . Now how long it will last is the money question ,
could i go back to 9 on my opti , never.
Somebody on the rohloff site has just covered 500,000 with no
mechanical issues.
For you roadie boys no pulling up at stop lights and furiously
changing down or lifting the wheel . Pull up in 14 flick it to 1 . I
do think the 13t would be more suited for the roadcrew . i will be
testing it over the next few weeks . The 15t gets me up my hills and i
have to use 1 for the steep climbs. Keeping up 90 cad in 14 is a
workout but it really flies and I have DH maxxis minions 42 tackys on
mine ..

Cakey,
I was looking through this thread on the mtbr forums at various
angular orientations for the Rohloff Ext Gear Mech cable routing.
http://forums.mtbr.com/showthread.php?t=241727
You arranged yours at the 6 o'clock position, with the shift
cables going forward at the 9 o'clock position.

I would like to still use my kickstand with the Rohloff installed:
http://www.jakirk.com/850XLi/pages/850XLi_04_JPG.htm
So, I wonder. Did you consider orienting the Ext Gear Mech at the
2 or 3 o'clock position so the shift cables would be pointing at about
10 o'clock and go up the back of the frame yet still clear the disc
brake and rotor? Seems like it would be possible-what do you think?

Hi Jim
Yes you could do that , my reason was I did not want it
too tight as it was a 1st go on this bike . And after the hassle of
getting the cables through left a bit of slack .

Cakey,
Love those Germans :) There are lots of good installation videos
[no sound on any of them] on the Rohloff web site:
http://www.rohloff.de/en/download/video/workshop/index.html
To get the video's to play I had to use a video converter program
since they wouldn't play in Windows Media Player as they came from
Rohloff. I've converted them to mpeg-4 videos [which do play in
windows media player or Quicktime].
http://www.jakirk.com/Rohloff_Videos/
The one on sprocket changing is great. Nice installation aids don't
you think?
So, another question for you. With no detent in the Rohloff
twist shifter how does the twist shifter "feel" when you change a
gear? Does your hand feel a change in resistance when you get to the
next gear or do you just feel the cadence change? If you went from
Gear 14 to Gear 8 would the turning of the twist shifter let you feel
going through Gear 13, 12, etc.?

Yes its a noticeable feel click , but there is no extra resistance in
lower or higher . There is no resistance as there is no cable
tightening. You just feel the cadence .
Going through the gears , i flick from 14 to 8 , 14 to 1 , 1-4 , any
combo is fine apart from high to low with power on .

My Rohloff 13T OB1 install is done and WOW. Straight out of the box,
smooth as silk, fast as lightning. The big rotors are a must.

Shifts are so sure with an awesome range of gears. My ride tonight was
brief but breathtaking so more detail to come.

How did the cables go in ? any nails left / wire marks on hands . Be
careful of 7-8 change until its run in , may drop into 14 .
You will love it even more over the next few months . Not fitted the
13 t to mine yet , how is 1 for the hills ?
Out of interest i rode my intense last night , ran out of gears on the
27 speed not has high geared as the opti , with 13t you should be able
to ride down Everest with gears to spare.

Threading of the cables ended up being easy, guided by a wire coat
hanger with the cables attached with gaff tape. The sleeve is
impossible to remove, I wrenched it as hard as I could & it snapped
off, then drilled the remnants out, shards of OB1 dispersing all
around me, a bit nerve-wracking. Clickbox, torque arm placement &
cable routing took the most time. Also meant I lost my kickstand, a
small price. I haven't ridden it for more than 10 minutes yet, but I'm
going for a ride shortly and I'll be keeping an eye on the speedo
especially downhill in 14.

39.1 mph or 63 km/h  on very slightly rolling (+/- 1%) flat tarmac.
Cakey has already said so much about it, so forgive any repetition.
Shifts between 7 & 8 and 10 & 11 need a throttle feather. Hopefully
the 10/11 shift will improve with some serious miles.

My intial impressions? Mind-blowingly awesome. I can't imagine how
fast this is going to be on the downhill section I used to hit 47 mph
on.

What speeds are we looking at electric-only? If these become a factory
option, will Opti need to ship with the largest cog installed to keep
them legal?

Hi Remf
The cables is the tricky bit as i said earlier .
Mine is like silk now . after 500 miles it becomes buttery
smooth . 7-8 shift and 10-11 stiffness disappears. When I rode my mtb
yesterday it felt so backward having to gear down to start off at
junctions .
Whats scary is that the opti at high speed feels wonderfully safe .
not sure if thats a good thing . On my roadie i know when i am
reaching its limits as the frame starts to whine .
Piccys please

Thanks cakey, your trailblazing is much appreciated. I don't see any
constabulary or even cars where I ride most, the back rural roads
around here where there's only the cows to look at you. It's bike
nirvana. Haven't had the time go on a long ride, so no big downhills
yet. It's scary enough at 45 on one huge mogul-ridden downhill stretch
I love but I haven't felt any whine or shudders. Maybe at 50? I tried
out 1st & 2nd up my very steep paddock, thinking it might struggle
with the 13T. No worries, it flew up the grass. The red earth is from
a pool excavation, perfect for jump building :)

Nice looking install. I see you used the Rohloff Torque Arm and
not a speedbone like Cakey used.
http://www.jakirk.com/850XLi_1/850XLiRohloff/Rohloff_03.html
Can you elaborate on why you went with the Torque Arm?
When you get the chance can you post some more pictures of your
install? I'm particularly interested in shots of the front and rear
cable entrance area into the Opti.
Thanks.

Jim, I ordered the Speedbone...twice. It never arrived, so I went with the torque arm. The only issue is it has to be unbolted before the wheel can be removed. I think maybe the Monkeybone may be the way to go when they make a 203mm version. It seems to be a neater solution for the OEM2 plate.


The front cable entry is a bit of a worry regarding water ingress, I'm going to get an aircraft engineer mate to knock up a replacement double cable lug for it.

cakey, that's the best way if I can find one, if not I'll get a double
split plug machined.

I'll definitely post more photos, stats & hopefully video when I get
some time to ride in the next few days.

I will say that the install is best handled by a skilled cycle tech
working with you side by side. There's some scary bits, especially if
you're not steady with a drill.

Remf,
I've been in contact with Neil Flock who owns Cycle Monkey.
Here's some nice pictures of his Monkey Bone:
http://forums.mtbr.com/showthread.php?t=325268
It's a bit confusing here in the USA who is or who will be the
new Rohloff USA distributor and who will provide service. As I was
looking at where to purchase a Rohloff I got quotes from Harris
Cyclery and Bikeman. Finally ended up dealing with Neil at Cycle
Monkey because he was the most knowledgeable on the Rohloff and
expects to have a continuing role with Rohloff USA. I've placed my
order with Neil, who has just ordered a number of Rohloff hubs
directly from Rohloff Germany. Here's a link to my quote:
http://www.jakirk.com/Rohloff/Jim%20Kirk%20Estimate%20090818.pdf
I should get the parts in 2-3 weeks.
I think the split plug you and Cakey discussed is the best way to
go to seal the front and rear openings. One no machining solution is
to use a push in tapered round plug [i.e. rubber stopper] and use a
hole cutter to put two through holes in the plug to accommodate the
cable housings [each housing is about 5 mm]. Then cut the round plug
in half with a razor blade and you've got a push in split plug which
should work well.
Remf, what is the diameter of the front cable hole you ended up
with? Did you enlarge the rear Opti frame hole? Also, did you take
the internal Opti parts out before drilling? I'm hoping that I can
just put the bike in the stand, turn each hole so it is pointing
somewhat downward, turn on the vacuum cleaner, and then drill.
Hopefully the chips then stay out of the Opti internals.

That monkey bone looks nice . The rears will not need opening up as
they are more oval in shape so the cables sit side by side .

Also you need to remember the 13t sits a bit further away about 5mm
than the other sprockets . Not a problem unless like me you like
perfect allignment , Its just a case of add a shim or 2 .

Jim, you will not be disappointed. A bisected rubber stopper or plug
with silicone is the easiest way, though I think a machined
replacement would look better. Both openings are 8mm. I tried to pull
out the sheath with pliers from the front, it moved about half an inch
before it snapped. Try to remove the sheath from the rear, it may work
better.

Mine just pulled out with pliers. Whats the high gear like with the
13t ? On another point don`t you just love the way you can flick
through the gears, and get an immediate change, and not have to wait
for the rear mech to decide . along with with the usual chain noise .
You will occasionally for the 1st 500miles get a weird meshing sound ,
I was told this was normal until its run in .

Honestly I haven't ridden more than 30 minutes yet due to commitments
but I plan a big ride today and will report later. I haven't even been
downhill yet! High gear on the 13T is probably only for big, fast
descents. How fast? Not sure yet. I've had some meshing, but nothing
too disturbing.

I've got a Holy Roller on the rear & a High Roller Semi Slick on the
front both at 65 psi.

Re the 13T gearing, I went for a ride a little while ago. The outbound
leg was in Eco mode mostly downhill. I found I was mostly in gears 9,
10 & 11 on the flat bits, sometimes 12, at ~ 25 mph average over 10
miles, topping out at 42 mph downhill in 14.

For me, gears 13 & 14 are downhill only in Eco mode. In Fast mode for
the return leg, 13 & 14 came into play on the flats, maxing out at 35
mph. Then climbed 400 ft over a mile and a bit, where I was mostly in
7th & 8th, 9-10% grade at ~15 mph.

The meshing only occurs when powered between some shifts, 7 to 8, 10
to 11 and another which I forget, requiring a throttle flick while
shifting, like a motorbike. No meshing on pedals only.

500 miles to run in? Won't take long. The Rohloff makes you want to
ride even more.

Not having done 1,000 km yet, the shifts are still stiff under throttle. In fact only 2 in the most used 8-14 range seem to be possible without the flick, 9-10 & 13-14. According to the manual, falling in neutral gear is possible while shifting under pressure (throttle). 


From the Rohloff manual:


When changing, gear coupling elements inside the hub must move and when there is more pressure on the pedals it is obvious there is more pressure on these coupling elements resulting in a harder gear change. Whilst stationary or when there is less pressure on the pedals, the twist shifter has less resistance and therefore a lighter gear change is possible. In a situation whereby it is not possible to reduce the pressure on the pedals (e.g. hill climbing), it is still possible to change gear quickly and smoothly. Simply change gear when the cranks are in a straight up-down position where hardly any pressure is being applied upon the pedals.

ATTENTION

Changing gear with the Rohloff SPEEDHUB 500/14 with pressure on the pedals is not necessary when being used appropriately. However due to the robust construction of the Rohloff SPEEDHUB 500/14 changing gear under pressure is possible and is not harmful to the hub. It is however possible that when changing gears under high pressure the hub could accidentally fall into a neutral gear, this is due to the coupling elements not seating correctly into the next elements and therefore rebounding back. If this occurs the rider could lose balance and crash. Changing gears under high pressure is at the riders own risk.

Particulars:

If changing up and down slowly or under high pressure between the gears #7 and #8, it is possible to fall momentarily into gear #11 or #14.

I updated the firmware to MDDRV507 & now have the 2 power shift modes with a few toggles of the Speed switch. Note this is different from Fast & Eco modes. It seems to be an aggressive / normal mode for the surge level in both Fast & Eco modes. Maybe Craig can explain better? Anyway in the low power 2 LED flash mode, some throttle-on shifts with the Rohloff seem easier. Back to the high power 3 LED flash mode and most shifts are stiffer and not entirely possible under throttle.

I tried a -8% average downhill in 14th, no throttle. I got to about 40 mph.

Back up the hill, for the first time ever - no pedalling, 8% average (15% in parts),   in 2nd, 3rd, 4th, 5th, 6th & 7th. I get to about 18.6 mph at the top, averaging 8.2 mph for a 400 ft climb over a mile. That 1.14 horsepower really does heave me up unassisted all the way, not that I'll try that again.

Remf,
Are the Rohloff shifter gear numbers visible and aligned with the
Rohloff shifter mark so you are able to see which gear you are in?
Also, does the Rohloff shifter work in the same direction that the
SRAM shifter did [ccw-or away from your-towards gear 1 and cw-or
towards you, gear 9]?
Can you tell me more about the firmware upgrade? How do I know
which firmware I have now? How do I learn what benefits are gained by
upgrading the firmware? How, exactly, do you upgrade the firmware?

You can see easy which gear you are in , just like a normal twist grip
1- 14 like throttle twist down towards you

The shifter's on the left so it's reversed like the SRAM, shift up is
a twist towards you.

I don't know much about the firmware upgrade, except that it has the
new surge level adjustment. Not sure how you check what firmware
you've got.

You need the five files from Opti (I got them from a new Opti owner
friend) & a PC or Mac running Windows XP to install it. Connect via
USB to mini-USB cable into the plug on the left of the headlight
display.

Firstly you need to install the USB Driver file, CDM 2.04.06.exe. Then
find out what port your bike is using by going to Device Manager /
Ports list (right-click My Computer then Manage) and look under USB
Serial Port, 20 in my case. This is your Optibike port.

Open PicBootPlus.exe. Click the Search button to find the firmware
file, MDDRV507.hex.

Check the EEPROM box, set BaudRate to 38400 and second BaudRate below
to 19200.

Change the port number to your Optibike port number in the text box
next to the Change Port button, then click the button.

Make sure the bike is on, then click the Write button in PicBootPlus
and move the bikes battery selector switch to the middle position.
Turn the bike off. Wait 5 seconds and then move the Opti battery
selector to the forward / internal battery position. Updating will
start.

If successful, All OK is displayed in PicBootPlus.

Hi Jim
I think the updates tend to be if you have had to make
changes IE aux battery mod , thats when i had to do mine.
Opti send you the file by using a share zip link which you have a
certain number of days before it runs out.
I understand what you mean though , its mentioned in Bikeons post
regarding how opti seem to send out fixes and updates and other owners
have no idea what the issues were.
It is quite bizarre the way they sometimes do things . like sticking a
plaster on but do not want to tell other people to duck their head .

Well put, cakey.

Without wishing to criticise, I've said for years now that the
Optibike website should have a service area.

Bulletins could be simultaneously issued to all owners, keeping
everyone up to date.

We are talking about an expensive item that involves transportation at
high speeds. How would Optibike issue an urgent Service Bulletin
should the need arise?

Logically, like other transport manufacturers, both critical & non-
critical issues are best handled by a service oriented area on their
website.

My 2 cents FWIW.

I tried out the steepest descent (except down a mineshaft) I could
find around here.

-16% for about 260 ft where I hit 45.12 mph or 72.61 kph momentarily
in 14th.

Remf, can you describe the few toggle that change these modes? I'm
assuming the 2 or 3 led flash modes refer to the LEDs flashing on
power up. Correct? Thanks for your informative posts.

Jim, switch between Fast & Eco quickly 3 or 4 times. You should see
the 2 or 3 LEDs flash to indicate the power surge level. Yes these are
the LEDs you see on power up. If you don't get any LED flashes then
you'll need to upgrade your firmware.

With the firmware upgrade, there are now 4 power settings. From what I
can gather, they work like this: (correct me if I'm wrong)

Fast / High - fast mode gives unrestricted surge duration at high power level

Fast / Low - unrestricted surge duration at lower power level

Eco / High - restricted surge duration at high power level

Eco / Low - restricted surge duration at lower power level

Thanks remf, great info. When I toggle 3 times I get the change.
Makes sense, start in fast mode, toggle 3 times and it changes the
mode, all three LEDs flash or just the two right LEDs. One toggle is
a cycle from starting position to other position and back. I'll
experiment on the next ride as I just got back from my ride for the
day and am charging.

Now back on topic: About 1000 plus feet of up followed by 1000 ft
down maxing out at over 45 mph on 1.5 lane mountain road. Then some
jeep trail (sandy rocky stuff) up and down to try out the dirt side of
the bike. Great fun. More on http://weightloss.optibike.com tomorrow
when I get home.

Gotta say the SRAM didn't miss a beat.

Sounds great, Jim. Riding the back country is the best. Just read your
blog, you'll be back to peak fitness in no time.

I really like the SRAM setup when everything's tuned & lubed. I had
the X0 & it was fine, no major adjustments, although the obvious trend
for the SRAM setup is that it starts out beautifully and eventually
with lots of miles, needs adjustment & replacement of parts, gear
cable, hub, cassette, chain-wheel, etc. With the Rohloff, the reverse
is true. It starts out clunky and begins to work beautifully after 600
miles or so. All you need do then is replace the oil every year.

One thing I did find with the SRAM & almost certainly the same for the
Rohloff, the gear shifter cable stretches after a while & is a culprit
for mashed shifts. XTR cable is preferable when you replace it.

Some very interesting notes about the Speedhub from Robbert Rutgrink of Santos in Sassenheim, NL.

Robert's a fan of Rohloff (who could blame him?) It appears that he's been using the Speedhub with his belt drive very successfully for a while. So much so that Rohloff are now going to support the Santos belt.

You can already buy a belt-driven bike with the Speedhub from Santos.

Hi,

I am stil waitung for my bike... but the rohloff hub is the next on my
list

there is another belt with a rohloff hub:
http://www.g-boxx.com/

Just one thing is open, how to open (and close) the frame??
Any ideas?

Enjoy the ride

Hi Jim

Thanks a lot for the link. If you are looking for job to produce
technical manuals in the maritime business let me know.
Perfect to do the exchange by myself

But there is a missunderstanding. Maybe, me posting was not clear .
I am looking for an idea to integrate the beltdrive of g-boxx.com. I
guess it should be possible to add some kind of adapter to open the
frame.

A Flash with some pictures of the beltdrive and also some withepapers
about it
