I'm having trouble find compatible chain rings for my now worn S2200 for my Epic Evo. It says on the 39T 120BCD and the inner is 26T
I have been told its 104mm/64. Just ordered a 26T 64mm and its way too small. Any idea's? or just the big ring as was thinking about 1x10 anyway.
thanks
Have you had any luck, I have the same crankset custom SRAM S2200 22/33, I'm now looking to use a 36T (although have seen 38/24 mentioned), the new chainring doesn't fit the spider, the current ring is a 104BCD with 90mm gap between the inner shoulders, looking at normal middle rings the gap is only 87.5mm (not wide enough) so won't clear the lip of the spider & sit flush.
The bigger ones are 120/80mm, unique to SRAM 2x10 cranks.
You can get SRAM rings from any dealer, X.9/X.0/XX are the same size. Alternatively Carbon-Ti do rings (for lots of money), or you can go custom. If you want to go 1x10 the latter is about the only option.
The 22/33 may well be different though - sounds like they're 104/64 from what you're saying Kwacker. Can you fit it with a bit of Dremelling? The bigger rings are a totally different size and definitely won't fit.
Dremel it is at the moment I think......a few mm to shave off !!
