Finalizing the brake upgrade for my X comp:
Shimano XT BL-M8100 L/R
Shimano SAINT SM-RT99 160MM Center Lock Rotors
Shimano GRX Calipers BR-RX400
Shimano R160D/D Disc Brake Adapter
about 50 miles in, feels quite a bit better than stock. Worth all the money, maybe not, but what are hobbies for?
Also recently added rib cage II carbon bottle cages, and swapped out the composite specialized pedals for raceface rides. The raceface pedals are super smooth and comfortable for 35$
