Using modern derailers

[RJM]

I was wondering if anybody is using modern 10 speed derailers with friction shifting?  I have some Ultegra 6700 derailers and was thinking about replacing the aging LX long cage rear on my Sam Hillborne with it.  I may replace the Sugino crank and install the Ultegra crank too but don't really know about that yet, I'm more interested in using the derailers.  I am using Phil Rivy hubs with a 7 speed freewheel in the rear, Sram 8 speed chain and shifting using Silver bar end shifters.  Any issues with using 10 speed derailers with 8 speed chain or 7 speed freewheel that you can think of? (the LX was always a bit too long in the cage area and the gearing I am using I can get away with a medium cage like the Ultegra I have so I don't see that as too much of an issue.)

As long as you can thread some 8-speed chain through the rear derailer pulleys without scraping the sides of the cage, I don't see a problem using it. I don't recommend changing the front, though. My experience with 9-speed derailers and 8-speed chains is that a lot of trimming is involved because of the narrow front cage.

I've never found a rear derailler that couldn't shift any given cogset
-- well, perhaps the old Benelux pull chain one I used on my first
conversion years ago.

That said, I've not used a 10 sp rd, but I have shifted 10 in friction
using Retrofictions -- no problems; quite the contrary, the shifting
was excellent. Old 8 sp era Dura Ace rd.

I have used 10 sp chains on everything from fixed gears through
7/8/9/10 with no problems. However, you might find that an 8 sp
chain's pins extend to far beyond the plates to fit through the
derailleur cages without striking them. Use a 9 or 10 sp chain.

I have friction downtube shifters on my Riv Road with Campy 9-speed. Works fine--I don't miss Ergo shifting at all.

This combo is working fine on my Rawland rSogn:

10-speed SRAM X0 MTB rear derailleur

IRD CD front derailleur

10-speed SRAM chain

8-speed Shimano cassette

Suntour friction downtube shifters

Bike aesthetics are not that high on my list of priorities but that Ultegra crank is damn ugly, even to me. Use the derailers but stick with the Sugino, IMHO.

Yeah, it's pretty ugly.  Frankly, all the recent Shimano cranks are ugly as sin. I will probably just stick with the Sugino.

 

Thanks for the suggestions from everybody, seems like it may be a good idea to change the chain to a 10 speed too (which I have on hand anyway). 

[Joe Bernard]

You'll probably need the Shimano cranks. That 10-speed chain will fall between the rings of your Sugino.

[Kris]

On my Coho..Sram Red FD and RD w/ 9 speed cassette and Silver dt
shifters. No problems. I would probably prefer 7 or 8 sp, but just
don't have enough motivation to switch.

[William]

He'd probably not use a 10-speed chain, since he has a 7-speed freewheel.  

[RJM]

this was actually going to be my next question.  Do you think I should just use the 8 speed chain that I have already (take a link out or two) or go with the 10 speed?  Will a ten speed chain work with a 7 speed freewheel? 

 

I do love the fact that with friction shifting it makes it so much easier to mismatch parts, makes this kind of stuff fun. If I can use an existing part I would rather do that then break out the new chain.

[PATRICK MOORE]

A 10 sp chain will work with any ~3/32 cogset, from 5 to 10. It's when
using "lower number" chains with "higher number" cogsets that you
sometimes (not always -- I've found that 9 sp chains work fine on some
10 sp cassettes) have problems.

Odd: the Surley Dingle 2-speed fixed cog needs at least a 9 sp chain.
8/7 speeders' pins rattle/tinkle on the adjacent cog. Wish they had
added what, .2 mm?, to the gap to accomodate all 3/32 chains.

I may be wrong, but I think I read somewhere you can use the narrower chain on the wider cassettes, but not the other way around, So if that's the case even if they change the space for the chain on the deraillers one should still be able to backwards apply the technology.

I'm not seeing all the posts.   I see NOW others have posted essentially the same thing. Sorry.  What's up with my Gmail?

[RJM]

So last night I took the drivetrain off the Sam Hillborne and replaced it with the Ultegra stuff.  6700 RD, Crankset, BB and an older Campy FD because the Ultegra is for braze on and I don't currently have a clamp for it.  It seems to be working fine with the 7 speed freewheel; I will do a test ride tonight to see if it all works well.  The Ultegra crank doesn't look completely horrible, it is the dark grey version and works with the other black components I had on the bike.  It contrasts well with the orange frame.  

[Joe Bernard]

I like the dark grey Ultegra cranks. Don't tell anybody..

I like the look of the Ultegra and like the Alfine single ring with chainguard even more.  Have one on my Surly Cross Check.  The lines just seem to flow in a way I like.  And the Q factor falls into the range I happen to prefer.  Guess having fat thighs can have an advantage.

I use the 6700RD with a 9x2 speed , closely spaced, HG cassette, the Connex 908 chain, and Silver DT shifters on my Ram.  This may be the best shifting I have ever had, including SIS.  it's not obvious to me that 10 speed offers recreational riders enough advantage to justify the added cost and reduced durability.  A 7x3 set up should also work beautifully.
