This goes to eleven.

There used to be a time when the 105 name was synonymous with the budget build. These days, the gap between 105 and Ultegra is getting smaller and smaller. Seems like trickle-down principles do work, after all.

Redesigned for the 11-speed drivetrain, the 105 incorporates a lighter shift action to reduce wear-and-tear while simultaneously improving precision. Boasting robust adjustability that comes from new geometries, an improved spring balance and cable pitch, this derailleur is more precise than ever before.

The medium cage version can handle up to a 32 tooth rear cog with ease, so you don’t have to buy a whole new rear derailleur when you decide you want to start tackling those serious hills.

Available in black or silver.
