Set up my Kona Sutra with a 1x12 Mullet with Wolf Tooth 40T and 10-52 Eagle X01 cassette, chain, and AXS derailleur. Used the Rival AXS hydraulic brake/shifters. I was worried that the brake calipers wouldn't fit my mounts, but the system came with the correct adapter plate and bolts. Also had the fitting and tool to install the hydraulic hose fitting after cutting the hoses to length. I ordered the DOT grease recommended by SRAM, but you might get away with just lubricating the fitting with a drop of brake fluid. The grease did work perfectly, but was a bit spendy. This is a great kit. Highly recommend.
