Friction Shifting 10 sp
I am building up a traditional steel frame and I am thinking of using
downtube shifters in friction mode with double cranks. I never had problems shifting 7sp or 8sp cassettes with friction shifting. I was wondering if anyone had experince with 10 sp. My concern is the the distance between cogs is smaller and maybe the precision is too great for friction shifting. If I have to go to indexed shifting, I'll just install the Ergo that I already have. It's about style and not being practical. I'm not planning on any gear combinations that won't shift with brifters. |

go ahead and do it you will be fine, just watch for overshifts!

I tried friction shifting Campy 9 speed, but found it infuriatingly
difficult. I was using Shimano Ultegra DT shifters. You can make Campy downtube levers. Just buy their "barend" levers and a kit with the extra bits that you need to mount them on the downtube. I think Le Tour do the kit. I've got nice Campy 9 speed indexed downtube levers, which work a treat, and are ultra-reliable. One of these days I'll buy the indexing ring to go to 10 speed.

I prefer friction because I have a 60cm frame, with shifters on the ends of aerobars. The cable run is so long that it is difficult to keep indexing precise. rsquared |

Please let us know how it goes. I'm interested in doing the same, but would
love to hear your experience. Gary Jacobson Rosendale, NY "Paul Kopit" wrote in message ...

Not a big deal IMHO. p.s. not all shifters can span the necessary throw for Ten. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

begin quoting rsquared :

The cable run is so long that it is difficult to keep indexing precise. That's odd, because indexed shifting works OK on tandems. -- David Damerell Distortion Field! Today is Mania, March. |

A tandem has essentially the same shifting system cable friction as a half bike - my TT bike OTOH, has a lot more cable housing than either of my tandems, and doesn't shift as well as a result (not "bad", just not "as well").

I am running a DA 9 cassette (similar spacing to Campy 10) with a
Suntour Sprint rear derailleur, a Superbe Pro front derailleur, and Campy NR/SR shifters (which pull just enough cable). Works well for me. Personally, I like the shifting better than with wider spaced freewheels. The Hyperglide cassette makes shifts very quiet. Yes, you do have to be fairly precise in your shifts (which is why I'm replacing the Campy shifters with Rivendell Silver power-ratchet type models), but I got used to it quite quickly and I don't race this bike. When the DA 9 cassette wears out, I will set this bike up with a 10-speed cassette like my other bike. I expect it will work fine. I understand this system might not work so well with a modern Shimano derailleur with a floating pulley, but I don't know this from experience-just heard it somewhere.
