SH Race Carbon XC Wheels – 1290 g with DT Swiss 350 Boost Hubs

1290 g carbon wheels designed for XC

These SH Race carbon wheels are built specifically for cross-country mountain biking, where low wheel weight and responsive handling are particularly relevant.

The complete wheelset weighs 1290 g and combines carbon rims, DT Swiss 350 Boost hubs and Sapim CX-Ray spokes in a configuration developed around XC riding.

Rather than using identical rims at the front and rear, this wheelset features different widths for each wheel, with a wider front rim and a narrower rear rim.

30 mm front and 27 mm rear internal rim widths

The front carbon rim measures 36 mm externally and 30 mm internally, while the rear measures 33 mm externally and 27 mm internally.

This differentiated front/rear configuration is one of the defining characteristics of this SH Race XC wheelset. The wider front rim provides a different tyre support configuration at the front, while the narrower rear rim keeps the rear wheel configuration distinct.

Both rims are made from carbon.

DT Swiss 350 Boost hubs

The wheelset is built around DT Swiss 350 Boost hubs, using modern Boost MTB axle standards.

The front hub uses a 15 × 110 mm axle standard, while the rear uses 12 × 148 mm.

A Micro Spline freehub body is fitted to the rear hub. This drivetrain compatibility should be checked against your cassette before ordering.

Sapim CX-Ray spokes with spoke tying

The wheels are built with Sapim CX-Ray spokes. Spoke tying is also used on this configuration.

Together with the carbon rims and DT Swiss 350 hubs, the spoke configuration forms part of an XC wheelset designed as a complete system rather than simply a pair of lightweight rims.

Built for cross-country mountain biking

At 1290 g, this wheelset is clearly positioned towards cross-country riders looking to keep wheel weight low.

The combination of carbon rims, Boost hub standards and different front and rear rim widths makes this a dedicated XC configuration rather than a general-purpose MTB wheelset.

For riders comparing wheel options for an XC bike, the key points to check before ordering are the Boost axle standards, Micro Spline drivetrain compatibility and tyre compatibility with the 30 mm front and 27 mm rear internal rim widths.

Handbuilt by SH Race

Component choice is only one part of an SH Race wheelset. The wheels are handbuilt with particular attention paid to the consistency of the complete build and spoke tension.

The use of spoke tying on this model further distinguishes the assembly from a standard factory-built configuration.

If you are looking for a lightweight carbon XC wheelset and your bike uses Boost axles and a Micro Spline drivetrain, contact SH Race if you need to confirm the remaining specifications before ordering.

About SH Race

SH Race is a Franco-Luxembourgish workshop based in Rumelange, Luxembourg, specialising in custom and handbuilt bicycle wheels. For cross-country riding, wheel configurations can be developed around low weight, handling and the specific requirements of the rider and bike. Each wheelset is assembled by hand with particular attention paid to build consistency and spoke tension.
