Ultimate Protection
Prevents frame damage and compression when your rear wheel is removed, making it perfect for air travel or tight storage situations.
CHAINDOCK DUMMY HUB AXLE
Crafted from durable 6061 alloy, ChainDock is built to withstand the rigors of travel, transport, and regular use. Its adjustable axle length (130–157mm) ensures a secure fit for most 12mm thru-axle frames, while the built-in docking wheel keeps your chain properly aligned and allows for smooth crank rotation—perfect for quick maintenance. Whether you're packing your bike for a flight or storing it in a case, ChainDock protects your rear triangle from compression damage.
Easy Maintenance
Keeps your chain tensioned and aligned so you can spin the crank freely for cleaning, lubing, or drivetrain adjustments without the rear wheel.
Feel Safe Anywhere
Secures your drivetrain and protects delicate components inside travel cases or car trunks during transit.
Upgraded Versatility
Telescoping axle fits 130mm to 157mm hub widths, making it compatible with most modern 12mm thru-axle MTB, gravel, and road bikes.
