Sanity Check -> DA friction shifters with new 10 speed(6 posts)

Sanity Check -> DA friction shifters with new 10 speedAcesFull
Sep 29, 2003 6:38 AM
My beloved TT bike needs a new chain and cogset. So why not upgrade to Shimano 10sp if possible. Currently I have Dura Ace bar end sifters running in 9sp friction mode and a 52/39 Ultegra double with an Ultegra FD/RD.

It seems that it wouldn't be a big deal to just change the chain and cog set (with the 10sp spacer) to 10 speed DA without major problems.

Any experiences?

Thanks!

A 10 speed cassete goes on a shimano 8/9 hub.Friction works with everything,but the closer cog spacing will make hitting the cog a little touchier.

I'm using DA barcons in friction mode on two bikes, and I love 'em. One's an old seven speed and one's an eight--no problems at all.
FWIW, Grant Petersen at Rivendell has warned that with a nine-speed cassette, shifting is "linear in a bad way." I have no idea what that means, but I assume that with closer spacing, it might be even more linear, perhaps in a worse way. How bad could it be, though?

I don't know about the 'linear' stuff but given equal barrel diameter on the shifters, closer cog spacing means less incermental movement of the lever per cog. Said another way, 7 speed spacing allows for a bit more slop in the technique than 10 speed.

The 10 speed cassette is twice as expensive as the 9 speed cassette wholesale. That in reality means you will find deals on the 9 speed to put its retail closer to wholesale, but you most likely won't see great deals right off the bat on 10 speed stuff because it's too new. So you may end up paying more than double the price of the 9 speed cassette for that one extra gear. Ask yourself if that is really worth it?

The chain is also going to be about $12 to $20 more expensive depending on where you get it.

My advice would be to give it time or go Campy.
