Hi. I'm curious if I will be able these shifters:

will be compatible with an 8 spd cassette while in friction mode. Thanks!

ps - I'm not interested in the Ultegra 8 spd shifters.

IF the rear shifter has a friction mode, no problem.

+1 Should be fine.

Oh. I read the description incorrectly. I thought it said they were both convertable to friction. I'll give them a call to find out. Thanks guys!

They may not be compatible with 8-speed. 8-speed requires longer overall shifter travel, as 8 speed is wider then 7-speed.

RD's don't care about friction v. indexed. They are neutral on the subject. They do what they are told, within their operating limits.

If the shifter has a friction mode, you'll be fine.

There are tons of friction downtube shifters online:

SunRace also makes 8-speed shifters, but I don't know who sells them:

not to steal this thread, but in regards to SIS vs Friction, can I use Shimano Sora STI levers (8sp/double) with a 105 7sp (SIS) RD and 600EX (friction) FD?

If the FD has to be SIS as well, can anyone suggest a 7/8sp compatible double chainring FD, that comes in a 26.8mm clamp-on model?

thanks
