The XC Bomber is a modern lightweight and reliable cross country wheelset that won’t let you down with a range of premium components.

DT Swiss’s XR391 rims weigh in at only 415g / 440g each depending on wheel size. At 25mm internal they are the right width to run wide tires necessary to be competitive on today’s demanding Cross Country courses.   For those running tyres below 2.2″ the even lighter (from 390g) DT Swiss XR361 is available with an offset spoke bed. The use of a specific profile, the custom alloy and the use of the PHR washer reinforcement allows for rims which are wide, strong and light.  Smaller wheel sizes will be spec’d 28h and larger 29″ rims in 32h.

The legendary Hope Tech Pro4 hubs need no introduction. UK designed and manufactured they remain unbeatable in all conditions. Hands down our favourite brand of hub manufacturer.  Meanwhile our in house range of Bitex hubs have a 6 pawl freehub and are equipped with long-lasting TPI sealed bearings throughout and are weatherproofed in house. All options feature large flanges, increased bearing sizes, and a sturdy freehub body for those that want a stiffer wheelset with hub internals that will truly take an off road beating. Easily serviceable throughout and with swap-able plug ‘n’ play freehub bodies, end-caps and rear axles alongside  mean that the XC Bomber’s are wheels for life suitable for your current frame and beyond!

A variety of spoke options allow for fine tuning.  Butted spokes bring performance and longevity at lower cost: light riders below 75kg and/or those with excellent line choice and technical ability will benefit from the weight savings of the Sapim D-Light whilst the Sapim Race is an excellent all round spoke.  Riders of all weights and ability who are looking for a truly performance focused set of wheels can opt to upgrade to the Sapim CX Ray.  Bringing further weight savings along with a fatigue life that’s through the roof, bladed spokes aren’t just for your road riding lycra clad mates!

Final customisation comes in the form of upgrading to PHR compatible Sapim Polyax Double Square 7075-T6 Heat treated nipples in your choice of full stealth black, a range of bright anodised colours or your choice of custom chosen coloured highlights either side of the valve to show that these wheels really are just yours!

100kg total system load.

All our wheels come equipped with two layers of high end tubeless tape, professionally installed free of charge.
