I have used Shimano 10 speed cranks with 9spd chain, derailluers and gears. Without actually having tried it with the Campy components you list, I see no reason why it shouldn't work. The only difference between 9spd and 11 spd chain is the exterior width of the chain. The interior dimensions are identical (i.e. 3/32 of an inch wide, 1/2 inch long). The ...


Assuming you have already backed the B-tension screw all the way out, I believe your B-tension spring has simply lost its tension. Mine is the same way. I know that spring is replaceable in some derailleurs, and checking whether it is in this one is on my list of things to do. Check with your local bike shop.


While using a Sora with a 36t cog may not be "approved" by Shimano, it's at least worth trying. The real problem is getting clearance on the large cog, not the capacity of the derailleur. This clearance is generally adjusted using the B screw derailleur adjustment. http://sheldonbrown.com/derailer-adjustment.html#btension If you are not able to use ...


Generally, with a 36T, you want a long cage (Shimano SGS), such as a Deore rear derailleur. While the capacity calculation you've done says OK, the max sprocket for a short cage road will be in the 20's or low 30's (in this case, its listed as 32t). Thus, I'd buy a long cage RD (or at least medium cage).


Not really. A current short cage Sora derailleur (RD-3500-SS) has the total capacity (i.e., 37 > 24), but does not support a maximum sprocket over 32. While the Sora short cage derailleur should be able it can take up the chain slack, the top jockey wheel may not properly clear the 36 tooth sprocket.

According to this page, the tooth capacity of the short cage version is 31 teeth. But let's look at a road bike with a relatively small gear range. you're likely to find. Filling in your formula, we end up with 52-39 + (23 - 12) = 24 Even the smallest cage derailleur would most likely cover that range. 52-39 is a standard road double crankset, and ...


That chain connector is not only for single speed, but I believe it is for 1/8" chains as well, so you may have a track chain, which is not meant for multi-speed drivetrains. If it's not an 1/8" chain, and is instead a 3/32" chain, and your drive train is 8 speed or less, you can just replace the master link and you should be good to go. The master links ...


Yes you have the wrong part. Count the number of cogs in the cassette / freewheel. Get a chain for that number of speeds. Probably a 9 speed.
