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

Shipping and duty handling can vary by destination. If DDP (Delivered Duties Paid) 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, headset/steerer, and internal routing standards. If you’re unsure, send us your frame model, model year (if known), and groupset (Shimano vs SRAM) and we’ll help sanity-check fit.

Stem lengths run 80–110 mm, paired with drop-bar widths (W1) of 360–440 mm and upper-grip widths (W2) of 350–430 mm. See the size table above for valid combinations.

W1 is the drop-bar width and W2 is the upper-grip width, both measured centre-to-centre in mm.

The Classic II fits a 28.6 mm steerer.

The Classic II uses a detachable stem cover for full internal routing; the Classic I is available in a semi-internal routing design.
