    Derailleur Pulley Wheel SRAM Red vs Force/Rival

    Just found my 2012 Sram Red Rear Derailleur upper pulley wheel has a radial crack all the way through. Replacement cost for set (upper and lower) is a hundred bucks, and I only need the upper. Found the Force/Rival set is around 12 bucks. I don't care about weight or ceramic bearings at this point, just want to know if shifting/fit would be the same.

    Or if anyone knows where to get just the upper pulley?

    Thanks,

    Shux, I'd gamble the 12 bucks. I could be wrong but I couldn't imagine that there would be issues with shifting or fit.

    Just as follow-up... I bought the Force/Rival set and they fit no problem (just used existing bolts and washers). Upon removal of the old ones, I found both wheels were cracked, the bottom just starting on the ID - so I ended up replacing both. I noticed the drive train maybe a little louder when turning the cranks on the stand, but not noticeable when actually riding. Shifting not affected, and I sure couldn't feel any weight or resistance difference.

    They're jockey pulleys, I can't think of any drive train component having less influence on things.

    'brifter' is a lame word.

    Are you absolutely certain you can't feel any weight difference?

    I've got some bikes, some guns,
