Campy Ergopower Shimano Sram compatibility ( shimsramnolo )

One of the "integration" project which i have in mind and always wanted to do is an integration of Shimano and Campy ergopower brifters together and having to used them will be quite nice having the precise "clunk" instead of the "click" from the Japaneses counterpart. If it wasn't for the "pull factor" which is different, we could have used a roller pulley that act as a cam to pull more cable but that aint sleek to built up with a campy rear derailleur. With a lil investigation from Zinn http://www.velonews.com/article/73404/can-you-run-campy-shifters-with-a-sram-drivetrain-sure-why and a email back proves the concept that it can be done and might be worthy of an project.As being mention in the article that SRAM having the same width as SHIMANO's cassette , decision is that to use the existing cassette i have lying around.


Taking on the challenge to get it done. And faced some difficulty obtaining the parts as required. Ordered a Sram Force but it wasn't delivered wasted 3 weeks for that. (lost/stolen along the way, freaking pissed over it...) thus order a RIVAL instead which i think can get the job done since its the same and it took another 2 weeks to come. Meanwhile ordered the shifters which took a week to arrive from BIKEPRO.


Now putting it together wasn't as easy as pure pedigree grouppo. This combination require some of the "touch" as both component and its cabling is very much different. Tried for several hours to get it fine tune but the pull isn't the same as for the bottom high 5 to the top low 5 , the increased tension to further tighten the top 5 shifts well but not the other lower 5 ring and vice versa. And usually this is what happens with shimano and campy combi. In a gauge estimate , the top 5 requires more pull thus i had a lil idea to solve it. Finally ending this tuning at 2 am after 4 hours , i had to throw in the towel.

The next day , only way to know if it works is to shift it under pressure, using the Tuesday's nite climb route i expect miss shift or missed down shift but none happened and i am seriously pretty happy it works. Its nice to know after all the frustration , wait , grease and sweat and tired fingers.They preformed flawlessly.

I realize you made this posting quite a while back, but I was wondering if you could elaborate a bit on the "lil idea to solve it," you mentioned.

I'm going to be attempting this mix w/ Veloce shifters and Sram Rival everything else next week and any guidance would be a tremendous help, thanks!
