Very acceleration quick clincher rim for 27½ (650B) made of carbon fiber. Completely uncompromised, no doubt. Here many hours’ work is spent behind every unit in order to maintain the advanced material layup schematics. The chosen material is the best available. XC70 weight only 330 g, still very stable. 26 mm wide and 28 mm high profile. Tubeless ready. Finish is polished 6K plain weave with logo in silver. A hardcore racing rim for the raceday when the result really matters.
