      The Spur is a derailleur hanger extension that lets you use your existing rear mech to run wider gear ranges.

      The Spur allows riders to convert their road, gravel, cyclocross, or commuter drivetrain to a 1x system with a single chainring without giving up the gear range of a double. It’s also perfect for riders who simply want to run a bigger cassette to get lower gearing for those really big climbs. With the spur you can go up to a 40T cassette without having to buy a new rear derailleur and without compromising the shifting on the smaller cogs.

      Install the spur in less than five minutes at home.
