the new crankbrothers cobalt wheelsets are a perfect mix of strength, performance and stiffness for cross country and trail riding.


“i worked closely with the crankbrothers engineers and product managers to improve the wheelsets. it is great that all the r&d crew are also riders. the new wheelsets are stiff, light, and robust. crankbrothers wheels have been my loyal companions on many riders in the most remote corners of the globe.” – hans rey : iodine rider


when we test new wheels, we push the prototypes in all kinds of real world situations. with the new opium design, everything was considered: rim width, shape, height, material, joining, etc. with the redesign, we wanted a better seal for tubeless, more stability, and a rim that wasn’t so hard and stiff it would flat, but that it could also hold up in rocks and big hits.
