What is the difference between the Sram S350 and Rival 1 Cranksets ?
The S350 crank is listed as an alternative to Rival 1, but they cost the same. All that I can see having visited the SRAM website, is that the less sexy S350 is 30gms lighter than the much reviewed Rival 1, however the S350 only has 4 chainring options vs the Rivals 7 chain ring options. This last bit confuses me, as they both use SRAM X sync chain rings, which are presumably the same BCD, although this isn't listed, so why the limited options on the S350 ? (My BB is a PF30)
