Lately I've missed my higher gearing and I found the 1x chain line just wasn't great. I've also perfected my FD tuning on my road bikes, plus I've started to immersive wax my chains. I figure it was time to revisit 2x again!
I'm running a GRX 812 1x RD in 2x configuration with aftermarket steel bearing jockey wheels, a GRX 400 FD + Venzo braze-on clamp, Shimano 11-36t XT 10 speed cassette and GRX 400 shifters. I was able to offset the weight gain of 2x by going with a carbon crankset and direct mount 46-30t chainring. Plus I dropped about 60-70g going from an 11-48t to an 11-36t cassette.
