Chain Keeper
A simple, dependable tool you’ll reach for every time you remove your rear wheel.
Whether you’re detailing your bike at home or packing it for the road, this precision-made dummy hub keeps your chain exactly where it should be. It holds the drivetrain under tension for effortless cleaning and lubrication, and prevents chain slack or frame scuffs in transit.
Fits all 12mm thru axle bicycles, road, gravel and MTB.
Features:
- Smooth ball-bearing rotation for effortless spinning and to protect your thru-axle from wear.
- Extended chain guides hold your chain securely during cleaning or travel.
- Durable glass-fiber reinforced ABS construction — tough enough to be dropped on concrete, and resistant to grease and cleaners.
Designed and built by an engineer who rides every day, each unit is produced in small batches in the USA and individually checked for fit and finish. Ready for use in your workshop or travel case.
Thoughtful, practical, and beautifully made — the perfect gift for any cyclist.
Built by cyclists, for cyclists — designed and printed in-house with obsessive attention to fit and function. Like all 3D-printed parts, minor surface texture variation is part of the process. Not happy with yours? We've got you.
