I've tried searching these boards to no avail trying to find a link to a SRAM compatibility chart someone posted. Looking to replace my rear derailleur and may as well go down the Wifli route but don't want to buy something that means I'll have top replace the shifters as well. SRAM's web site says their Wifli RDs are compatible with existing groupsets but just want to make sure.

Bugger! Straight after posting this I found it.

I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.
