BMC Teammachine ALR One 105 Road Bike 2021
Amalgamating a sophisticated alloy frame, a full carbon fork and a precise and dependable groupset, the BMC Teammachine ALR One 105 Road Bike grants performance wherever you ride it, whether that’s in the mountains, through the valleys or across northern classics style terrain.
The frame utilises a refined grade of alloy within its construction, and this has a triple-butted internal format and smooth welds to deliver high levels of lateral stiffness within a low weight form. The full carbon fork and the frame’s seatstays enhance comfort at the front and rear of the bike respectively thanks to their Tuned Compliance Concept design while the D-shaped seatpost further smooths the bumps thanks to its advanced carbon layup.
Generous frameset clearance allows for the use of wide, plush and quick-rolling tyres and Mavic CXP wheels use their light but hardy rims to infuse acceleration and composure into any ride. Gear changes are courtesy of the Shimano 105 setup, and this changes through the ratios with ease and reliability every time of asking.
Highlights
