I'm interested in the SRAM Quarq Red GXP Powermeter. I currently have SRAM Force derailleurs and shifters on both bikes. Can I use this on my bikes? I was concerned about a compatibility note on the SRAM site mentioning the new Red Yaw front derailleur. Also I guess I just can't buy the derailleur but would need new shifters as well?
