At 16.5 stone you'll never be a great climber no matter how strong you are.
It's physics, innit. How you'd lose weight I don't know, as you say you're
already fit. Is it possible to somehow lose muscle mass?

They weigh several stones less than you. Me too in fact, I'm a similar
build to you. Actually, wondering about your performance as compared
to that of armstrong and ullrich is only going to lead to confusion
and disappointment all round, best not think about them. :)
Weight is a critical factor when it comes to climbing, heaving the
extra mass upwards adds a great deal of work to the equation, and the
extra bulk in the upper body doesn't really help very much in that
situation. Being small and lean gives a great headstart when you have
a mountain to get up. Sprinting as you have noticed is a very
different kettle of fish.

Losing weight will make you faster up hills for sure, and so will
climbing more hills. Practice makes perfect.
Incidently, you say you can "easily hit" your max heart rate on long
hills, that suggests to me than that your max HR is higher than you
believe. By definition reaching that max is a difficult and very
painful thing to do, particularly on a bike I understand.

Is it a problem? If you want to be a great climbing cyclist, then yes,
you've probably got too much weight - probably several stone too much.
However you could look at something else, eg track, where your strength will
be more of an advantage (track riders have more upper body strength than
climbers), and just accept you're not going to be totally wonderful up
hills.
Depends how much you want to sacrifice to your cycling.

If you read his book Armstrong was not a very good climber but the
medical treatment he underwent changed significantly his body shape and
with it his ability. So unless you are planning something radical, you
may just have to accept it.
Tony
Why do you think the upper body muscle will help?
For reference, I think Lance is about 5ft 10 inches and weighs about 11st
4lbs when racing.

I am 39, six feet two inches tall and weight 11 stones 3 pounds. Since
I lost four stones I can climb much better and faster than I used to be
able to and faster than some of the younger riders with whom I ride. My
waist is about 32". Upper body muscle is not useful for climbing, its
just weight to be carted around.
Lose some weight and practice rding the hills. Running might be the
problem, you need cycling muscles for cycling not running, I bet Lance
Armstrong doesn't run very far when he's in training.

Lance has relatively little upper body development. Most of the really
good hillclimbers I know are built like whippets. Upper body weight
really does not help you on climbs.

I lost just under 4 stones in 2 years by healthy eating, very little
booze and plenty of miles. It wasn't really hard just takes lots of
time to put the miles in. My wife is on the healthy eating plan so its
easy for me to eat healthy too. She is also pretty cool about me being
out cycling so much. I realise not everyone is lucky enough to be able
to spend as much time as me indulging in cycling.

Running almost certainly isn't the problem. Before he concentrated on
cycling Lance was an extremely good triathlete. If you want to lose weight
running is a better way to do it than cycling because the power output is
normally higher. It is also probably a better way of improving your
aerobic capacity. However, cycling is more specific in its muscle usage
than running so if you want to be a really good cyclist then you need to do
cycling specific exercises, including weight exercises for the legs.
I think you need to accept that you have some disadvantages when climbing
but you can almost certainly improve substantially.

Michael MacClancy
You will, as others have said, never be a GREAT climber. You should be
able, with training, to keep up with the rest of the pack.
Look up Eros Poli's stage win in the 1994 Tour de France if you want
true inspiration: he's 6'4" and was about 13.5 stone when he was racing,
yet he beat everyone over Mont Ventoux [1]. Magnus Backstedt is even
heavier IIRC, and he won Paris-Roubaix this year, although that's not
very hilly. You can often bump into Backstedt at Newport track because
he lives locally.
[1] actually, Poli *was* crap at climbing, but he'd put 25 minutes into
the peloton before the mountain - enough to keep him clear until the
finish at Carpentras. He said he only attacked because he had also been
out on his own for about 100 miles the previous day and was most annoyed
at being caught before the finish.

Well there you go. Ride your bike for a minimum of four hours a day,
every single day for six years, and you'll be well away :-)
Frankly those bastards piss me off no end. I am one of the fittest
people I know, and they go uphill faster than I ride on the flat. On
a recumbent! Bastards.
So, what to do. As everyone else says, keep the cadence high, the
gears low, keep your arse on the saddle as much as possible, and ride
that bike.
Now the important question: why should you care? Do they or do they
not wait for you at the top? Enjoy the ride, I say!

Pictures can be deceptive because he has very good muscle definition.
His upper body muscles, though not bulky, are well toned and he has
very little fat when racing fit.

There was a web site created by a Leftpondian that enabled you to
compare yourself directly with Armstrong or Pantani. You keyed in the
vital statistics of your best climb - distance, time, average
gradient, gradient and length of steepest section, total climb etc.
etc. etc. and it assessed what, for example, Lance's Alpe d'Huez
performance would translate to on your hill. The instructions were
quite involved but the last two were: read off Lance's or Marco's
virtual time for your hill; resolve not to give up the day job.

Oh that's good to hear. There has to be some advantage to being skinny I

something less than 55kg.. Err.. wonder why I can't?

Yeah. My weight had slowly crept up to about 14 stone by the end of
last year, and I decided to lose a bit. I was kind of surprised how
easy it was once I decided to do it. I lost a stone and a half in the
first couple of months of the year, by making sure I did plenty of
excerize (running and cycling) and just being sensible about food. Cut
back on the booze, cake, chocolate, etc. and take relatively small
servings at meal-times (you can always have another snack later if you
get really hungry).
Now I'm stable at about 12.5 stone and eat what I feel like, although
I still do plenty of excersize. I might do another half a stone
sometime soon, but I don't really need to be any less than 12 (I'm 187
cm tall and 39 yrs old).
> I realise not everyone is lucky enough to be able to spend as much

With work, wife and kids it can be hard to find time. Using cycling
as a form of transport helps - especially for the commute to work
since that happens every day. Also you can go riding recreationally
with the family. With smaller kids off-road is really better than on
the road I think. Of course small kids are going to be slow, but they
can improve fast. I often go out for a ride with my 6 year old
daughter, she can keep going for two or three hours without
problems. Kids don't seem to do hills well tho'...
He was already an elite cyclist before the treatment, winning the 1993
World Championship at the age of 21, the 1995 San Sebastian and 1996 Fleche
Wallone. He had also won stages in the TdF.
The loss in upper body weight resulting from the treatment has undoubtedly
improved his cycling performance but it would have also improved his
running performance.
The problem that runners have when cycling is that cycling is more specific
in its muscle usage, demanding greater output from a smaller number of
muscles. My point to the OP was that if he wants to lose weight (and
doesn't have loads of time to cycle) he'll find running of assistance.
I have a suspicion that his cycling performance would improve fastest by
spending a lot of his cycling time on a turbo-trainer and doing weight
training for his legs with lots of repetitions with relatively light
weights.

Michael MacClancy
True. I guess the loss of upper body strength (and mass) would have
impacted his swimming if he'd tried triathlons again.

How depressing. I'd consider climbing more hills. Not as controlled, but
doesn't involved staring at the walls. ;-)
Jon
He is still a good runner and takes part in the occasional duathlon,
here's an old article about Dirty Du 02:
http://www.adventuresportsmagazine.com/features/armstrong.htm
"he's apparently never lost the itch for multi-sport racing Armstrong
set a new course record at the Dirty Duathlon on December 8, finishing
the technical course (3-mile trail run/12.3-mile mountain bike/3-mile
trail run) in 1 hour, 36 minute and 5 seconds. Surprisingly, he had to
come from behind to win after Jason Sager out-pedaled him by 2:24
on the biking leg."
Doug
Dave
I agree, it isn't what I said. Weight IMHO is the OPs "problem".
Shedding some will almost certainly not make him an "Eagle of Toledo" it
might not stop him being dropped by his friends but I will probably make
him a better climber than he is today. Regarding running and cycling,
since I stopped playing 5 a side football my cycling has been far easier.
How is this regarding running and cycling? 5-a-side football is
certainly not running. It might have frequent bursts of short runs but
the way you use your muscles is very different to running. Twisting,
turning, moving backwards, moving sideways, and dynamic stretching, for
instance, are not likely to form part of a normal run of mine.

This has always puzzled me. Thinking in terms of simple physics, and
noting that lightweight cyclists race the same weight of bicycle as
heavier cyclists, and noting that as a person becomes more muscular,
the proprotion of muscle to the rest increases (e.g. your brain
doesn't get heavier), then the best hill climbers ought to be the
biggest guys with the most muscles, and the best of them will be those
with the largest bias towards leg musculature.
But it seems the skinny guys win.
This suggest to me that there is an optimally efficient human muscle
size, and that the larger muscles developed in gyms, while stronger,
must actually be significantly less efficient in terms of
power-to-weight ratio.

In the Centrum Ronde Van Vlaanderen in Oudenaarde, there's a bike on a
trainer hooked up to a computer simulation of one of the local "murs", on
which you can go up against a virtual Peter van Petegem. I beat him by
about three seconds, but of course it takes no account of Pie Consumption
and general lardiness. Put the pair of us on a /real/ hill and I suspect
things would be slightly different...

But you also need to consider the weight of the skeleton, internal organs
(perhaps bigger people do have bigger brains), skin and body fat, all of
which will be greater for bigger people and add nothing (larger heart
apart) to climbing ability.

Lots of things only scale with area rather than volume, such as lung
surface area, arterial cross-section. These are the limiting factors
(well at least something similar probably is). It is well established
that lightweights generally have higher (aerobic, at least)
power-to-weight ratios than heavyweights and I'm not aware of any
significant limits to that within a reasonably normal range of sizes.

Yebut, presumably for cycling up hills it's got to be the right
muscles. Upper body strength has little part to play, so big muscles
in the arms, chest and back are more or less just extra baggage.

Come on! D-Tek are visible across the fields on a clear day and you have
too many tin-cans in the yard already. Sell one and give the money to

is off on my 'bent.

There is the problem -- you're having to lug all that weight up the hill and
expend massXheight of energy to do it.
Drop a cog, take it a bit slower and keep doing it. You will be surprised
how quickly you will improve.
Also, for small hills on a regular route you will quickly learn how to build
up speed before the hill, where to hit the pedals and where to just drift.
That makes a massive difference.
Have fun.

I have tried persuading my wife that we don't really need two cars. (Having
one out of action confirmed this, but also confirmed that it can be a pain in
the neck. Having a nasty cold recently hasn't being encouraging either, though
I probably could cycle to Newmarket station if I was well enough to go to
work but not up to cycling the whole way.)
Neither of the cars would sell for enough to pay for e.g. a new ICE
(especially if I can't work out why the Ka now whines in fifth), though the
savings on tax/insurance/servicing would within a few years, and I don't
think my mother-in-law would be happy if we sold her car (nor would the lodger
be if we sold his) (I think there were some guests' cars there as well when
you saw them, adding to the "too many tin-cans" impression).
I do however have an angle grinder, MIG welder, and a small pile of bike bits.
Watch this space, but without holding your breath. (I haven't been to Kevin
for the "try out assorted recumbents" session yet though, that plan got rather
disrupted by the car dying.) I need to learn how to drive the GIMP too (and/or
a suitable CAD program). And probably to decide that I really do need to trust
my welding for at least some structural stuff rather than trying to avoid it.

The folder (which I didn't have at that time) would suit a much shorter and
lighter rider if I took the extra-long seatpost off. (Consists of the original
seatpost, plus half a seatpost and a length of seattube off another bike.)

Rather than MIG welding for hand-made thin-section bike stuff it's normal

But "take side view photos, scale to match, cut and paste bits" will
probably do for rough 2D design.

I've got an Amiga, which is at least 680x0 based. There was a very basic
(simple command line stuff only) Amiga emulator that ran on the Sun, but
the other way around could be trickier though, and I'm not sure if it's
working anyway. I am certain I don't have a tape drive.
But I think JohnM might have the appropriate kit.
(And somewhere I have Imagine for the Amiga, I ought to try transferring
it onto UAE. Assuming I can read the Amiga floppies.)

Yes, but I already have the MIG welder and a bit of experience with it,
and the pile of scrap frames are thick-section welded ones (thicker than,
say, the Alfetta body panels I got the MIG for).
There is an obvious downside to that, but it's not as if there are any
big hills locally anyway.

Yup, new edition is out now (and I must get one too).

Ah yes, there's a slightly older version available as an rpm with no
restrictions, or if you have Qt build the current version from source.

Mainly for MS-Windows, there's very little for Linux.

Only Sun 4s the last time I was in his server (bed)room.

Well watch out for distortion then....

I use AC3D, from here: <URL:http://www.ac3d.org/>. It's not true CAD,
since it doesn't really know about solids and doesn't have any real
dimensioning; but it is an excellent 3d modeller and visualiser. It's
shareware, but the license is inexpensive and in my opinion it's great
value for money. The author is also pretty good at responding to
questions and suggestions. It exports both to AutoCAD and to POVRay.

;; Diplomacy, American: see Intelligence, Military
Compare and contrast. You have already got some experience with welding,
are used to the welder you own and are using bike tubing.
I had no experience of welding, have access to an arc welder which is
easily twice my age and am now almost reaching a passable skill level
(Somewhere approaching almost competent!) as I reach the end of
producing my second frame.
I would strongly advise buying Atomic Zombies Bicycle Builders Bonanza
or at least looking at the site (www.atomiczombie.com). If for no other
reason than you'll realise that if he's still alive, it can't be that
difficult.
Jon
The assumption of a second frame is one reason for not worrying too much
about the weight of the thick tubed welded frames....
As it happens I do have an arc welder too, but I've never used it (it was
my father-in-law's), and when I did do arc welding it was on _much_ thicker
stuff.
>I would strongly advise buying Atomic Zombies Bicycle Builders Bonanza
That was my birthday present to myself. I'm thinking of something a bit
like the Kool Kat, but based on a 26" wheel frame (with a 20" fork).
I'm undecided between a 20" rear wheel, a 26" rear wheel with a very
steep head angle and hardly any trail, and cutting and bending the frame
to have a 26" rear wheel, 20" front wheel, and the headtube back at the
angle it first thought of.
(Or using a lighterweight fork that I could bend to change the trail, but
that's for a 451mm wheel I don't have, and would need either a lot of
threading or welding a different headtube in place (but does have a much
longer stem which might work for OSS without welding an extension onto it).)

Hmm. You're not getting me on one of those tallbikes just because I've
seen photos of someone else doing it....
I'm not convinced by something as low as the Marauder for commuting or
town use either.
You claim the first one was a prototype and treat the excess weight as a
good training exercise.

I've been playing with ours a lot recently and have finally managed to
get the hang (Sort of) of welding thinner tubes. I did however punch
neatly through the front derailleur mount tube by leaving the current at
70A and then attempting to weld a < 1mm walled tube to 1.2mm wall one. I
then got to spend about 4 hours this evening, laying up material around
the tube until I could successfully weld it. Grr.

My first plan for after Christmas is to make a Spincycle for the Bike
Station. I can see us getting grief from the management though, as the
station car park is probably not the best place for it, but is the only
large open area available.

Coward. I'd love to make one and then commute to work on it, but given
the hill I have to travel I can see a disaster in the making. Too high
for a Martlehat to be any use! ;-)

I'd stick a flag on it. TBH, the fact that you are so strikingly
different means you'd only have problems if you tried to jump places in
stationary traffic.

You and me both..
I have most of the necessary bits in the garage, just need to find some
time.
I'd like to find a smaller wheel than 26" though.

You notice that the place where Atomic Zombie lives is extremely flat. I
suspect that this makes the skycycle rather easier to deal with; I've
certainly no plans to try riding one around here.

Morning had broken, and I found when I looked that we had run out
of copper roove nails.

One Bob Johnson competed in the BHPC race at Milton Keynes on a tallbike in
2001, and reported that the martlehat was very useful when carving through
overhanging trees...
I have a car for use when I'm happy to sit stationary in traffic as
normal bikes pass it....

ISTR Chalo Colina admitting in rec.bicycles.tech that he had carved a
large groove in his scalp by riding his tallbike under an awning. A
PFDB might have helped in that case.

I'm sure you could find a flat bit to practice on before tackling the
Dalbeattie Slab.

Next time you're in Edinburgh pop into the bike station. They have a
huge pile of 20" (And similar) wheels out the back. The bearings may
need a service, but it'll hardly need to be perfect!
Jon
Every time I go through Waverly (fairly infrequently) the Bike Station is
closed. I'll have to ask a colleague who commutes Edi-Dundee (for the next
week anyway).
