SHIMANO has announced the launch of its all-new new TIAGRA R4000 groupset, a refreshed 2×11-speed mechanical drivetrain that’s aimed at the road segment that offers enthusiasts confident shifting, practical gearing, and a more accessible fit for a wider range of riders.
At the heart of the system is an updated shifter with an ergonomic lever design for easier reach across a wider range of hand sizes. Plus, a new lightweight 11–36T HYPERGLIDE 11-speed cassette is designed to deliver a broad range for mixed terrain and climbing, while helping reduce system weight by more than 200 grams, supporting riders who want a lighter road setup without sacrificing gear range.
