Shimano’s first and only 12-speed mechanical groupset is the latest addition to their premium road family. The 105 R7100 combines pure cycling with pure craftsmanship, delivering the wide gear range, hand-friendly ergonomics, and all-condition braking confidence you’ve always craved. Developed from Shimano’s Science of Speed philosophy, 105 raises accessible performance to a whole new level and is paired with a performance-driven Shimano GRX chainset for efficient power delivery with every pedal stroke.

* This bike comes with a Shimano GRX chainset for smooth, reliable shifting on mixed terrain. The FSA chainset shown is for illustration only.

Ribble alloy bars are built for real-world riding, with a compact shape that makes it easy to move between tops, hoods and drops. The ergonomic profile helps reduce pressure and keeps things comfortable, mile after mile. Paired with a matching alloy stem and wrapped in soft bar tape, it’s a setup that feels right from the first pedal stroke, whether you’re heading out for an hour or all day.
