SRAMano
I think I read this in the replies already, but Shimano and SRAM use the identical spacing of cogs so the derailleur tracks Shimano/SRAM or SRAM/Shimano perfectly either way.
This is slightly off topic, but related. I have been running:
- FSA compact crank with modified 52/36 FSA rings
- Mavic hub and now a PowerTap hub
- SRAM PG-1070 11/26 cassette
- SRAM PC-1070 chain (with a Wipperman link if you care)
It isn't flawless, but that is not a SRAM compatibility issue. Because the 52 ring has ramps to mesh with a 38 tooth inner, there is the need for a slight over throw on the front derailleur. How smooth it works is a fine line that depends solely on the mechanic.
