Just built the bike - easy group set to fit to the bike although I needed post mount adapters for the front and had to swap out the rear caliper for a flat mount as the post mount would not fit into the angle between the stays. Otherwise great and excellent value for a winter bike build. Excellent service from Merlin Cycles - great choice of stock, quick despatch and prompt, secures delivery. Definitely a return customer !!
Purchased to replace 105 5700 groupset with TRP Hy/Rd brakes and the difference is like night & day. Easy set up, shifting is super light and brakes are fantastic.
