Consensus on alternative Campy cranksets
Moderator: robbosmans
For those of you who have switched from Campy cranks to alternatives on a campy 11 speed setup, such as the Rotor 3d/3d+, what has been your shifting experience? I currently am rebuilding a TT bike and see that there are a few reconditioned SRMs available, mostly from Rotor. After searching this forum and other sites, I am not 100% convinced that the shifting performance will be acceptable. The Rotor 3D SRM will come with round Rotor rings, which supposedly are campy-compatible. I am considering purchasing Praxis Works rings that seem to have better reviews. Am I going to regret going with the Rotor vs. moving my Campy SRM around every time?
Thanks.
Thanks.

I had a hair of mid shifting with a rotor 3d+ (round rings and praxis rings) combined with a super record group but the big issue was probably chain line with the BBRight bottom bracket. Now it sports a campy over torque crank with spacers to get the chain line just right. (BBRight is 79 cm, mm overtorque is 86mm wide which leaves a little bit of play room for optimal alignment)

Which bottom bracket type does the frame have?
I've used Record cranks with Record rings, Record with Q-rings, Quarq Elsa with SRAM Red rings and Quarq Elsa with Q-rings. There's never been an issue with Campy Record EPS 11… everything shifts just fine once set up correctly.

Thank you all for the responses. It sounds like there should be no problems. This is for an older Cervelo P3 with a "standard" BSA bb. Currently I have ultra-torque cups which will be swapped out for the appropriate bb for a rotor 3d arm if I go this route.

The q-factor on the Rotor 3d (24mm spindle) and the Campy crank appear to be the same (e.g., 145mm). Is that correct?
The campy SRM is a bit of a pain to get on and off with the clip. I agree, not that hard, just takes a few extra minutes to get the bike setup.

If you notice the 1.5mm then something is wrong....
