Campagnolo/Sram
 

(sort of crossposted from Tandem Cycling)

I recently bought this tandem:

An '04 KHS Milano

It has shimano Sora shifters which I plan on replacing with a pair or late 90's 9 speed Campagnolo Record Ti shifters. My original plan was to use a Jtek shiftmate along with the og Shimano Deore RD on a Shimano spaced cassette. Somebody mentioned that people have had luck using Campy 10 speed levers with Sram exact actuation MTB derailleurs an a 10 speed Shimano cassette. This seems to be limited to the tandem crowd and there isn't much information out there about it. Does anybody think I will have any luck using a Sram MTB derailleur with my 9 speed Record shifters?

Thanks.

Campagnolo 10spd levers will work nicely with a shimano RD and shimano 8spd cassette.

Nobody can give me any insight?

I bumped the relevant thread to the top in the tandem forum for you.

SRAM RDs need uniform lever pulls and a Campy shifter produces nonuniform pulls, so the results won't be perfect by any means. Thre are also two version of 9 speed shifters. The earlier models pulled and average of 3.2mm per shift, while the newer ones pull an average of 3mm. I've never measured the pulls on a 9 speed shifter personally, but I have done so with 10 speed. While the average pull is about 2.8mm, the actual pulls are 2.5mm five times, 3mm twice and 3.5mm twice.

The significantly smaller pulls on the first five shifts are the problem. There will be lots of lag at the RD after those first five shifts.

I've been reading that thread(still have it open in another tab), but it just doesn't convince me. All of that pertained to new(ish) 10 speed shifters, while I have the older 9 speed (pointy hoods) levers. I ordered a jtek shiftmate.
