Looking to complete a build on the cheap as a rain/training bike. Looking for (at least) rear 11 speed shifter(sram/shimano) and derailleur. If you have a double setup I'm interested too if the price is right. If you have a n/w 42t 110bcd 5 bolt chainring too that's a plus! Sram is preferable since I already have the left ss brake lever and a force crankset. Truth be told I am a shimano fan so could be easily enticed in that direction.
