Orders ship once processing is complete and a tracking number is generated. Delivery time depends on destination. For an ETA, message us with your location and the exact item/size you’re considering.

Shipping and duty handling vary by destination. If DDP is offered for your destination, duties and import handling are included at checkout for eligible orders. If DDP is not available, duties and taxes may be collected by the carrier or local customs authority.

Warranty terms are provided by the manufacturer. If an issue occurs, Underdogs Cycling will guide you through the claims process and coordinate with the manufacturer where applicable.

Compatibility depends on your frame/crank standard and drivetrain. If you’re unsure, send us your bike model/year and groupset (Shimano vs SRAM) and we’ll help confirm fit.

Model A is the short version and Model B is the long version. The correct one depends on your frame’s axle length and whether it’s front or rear. Send us your frame model and we’ll confirm.

The axle weighs 25–28 g and saves more than 50 g compared with a conventional aluminium thru-axle.

Torque to a maximum of 20 Nm using a calibrated torque wrench. Do not exceed the rated torque.

It’s designed to fit most major bike brands via interchangeable heads, but always confirm your axle length, diameter and thread pitch first.
