Beast laces ultralight XS30 carbon rims into light & strong, trail-ready XC wheels

Tips & Reviews

German carbon specialists Beast Components have unveiled their first truly ultralight cross-country mountain bike rims, the all-new featherlight XS30. At just 315g per 29er rim, they take advantage of an ultra-fine carbon prepreg material that allows Beast to carefully layup a more detailed construction that they say builds a wide featherweight rim that is vertically compliant for comfort & flat prevention, but extremely stiff laterally for control & durability.

Beast are building them up now into bulletproof, if not ultralight complete wheels…

Beast developed the new lightweight XS30 mountain bike rims after getting their hands on the special super-fine ’35g carbon prepreg’ in a collaboration with Burmester audio systems in Berlin. With the uniquely high-quality material in hand, their engineers set out to build their most complex carbon mountain bike rim layup to date.

The result is said to be one of the lightest modern XC rims on the market, while achieving an ideal balance of weight vs. stability – all 100% made-in-Germany.

But these specially manufactured rims are not only light, but also comfortable, stable, and stiff. Through increased vertical compliance, you benefit from ride comfort. But also the precise handling known from Beast rims remains, through an extremely high lateral stiffness. So it allows you to always ride the best line on the trail.
