PERTUAL SHARP GR Carbon Wheelset

Q: What does the 47 / 53 mm depth mean?

It's a front/rear depth pairing: the front rim is 47 mm deep for lively acceleration and steering feel, and the rear rim is 53 mm for added aero stability and drive — the same approach used across the PERTUAL SHARP family.

Q: What tyres suit the 32 mm internal rim?

The wide 32 mm internal rim is designed for larger gravel tyres run tubeless at lower pressures for grip and comfort. Follow your tyre manufacturer's fitment and pressure guidance, and don't exceed the rim's or tyre's stated pressure limits.

The PERTUAL SHARP GR is the gravel-bred member of the SHARP carbon family — a wide, tubeless-ready disc wheelset built to float over rough surfaces while holding road-bike speed. A modern 32 mm internal rim (40 mm external) shapes big gravel tyres for grip and comfort, and a front/rear depth pairing of 47 / 53 mm blends acceleration up front with aero stability at the rear. Durable Sapim steel spokes (F21 / R21) and the PERTUAL Premium Road Disc hub on ceramic bearings keep the build tough and low-drag, at a claimed 1345 g / set.

How fast does it ship?

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 freehub you need.

Do prices include duties and taxes?

Shipping and duty handling can vary by destination and product type. 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.

What is the warranty?

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.

How do I confirm compatibility before ordering?

Compatibility depends on your axle standard (thru-axle), brake/rotor interface, and drivetrain/freehub type. If you're unsure, send us your bike model/year and your drivetrain (Shimano vs SRAM) and we'll help confirm fit.
