More info

RAR KERN represents the newest generation of aluminium wheels.

The basis material is a very high end aluminium. Compared to the alloys usually used to manufacture rims, its yield strength and stiffness is 50% higher, and its hardness is between +20 and +30%. 

This better resistance makes possible the manufacture of a lighter rim with similar or superior impact resistance and stiffness. Despite being super light with less than 400g per rim, KERN is also way stronger than many rims weighting significantly more. 

The braking properties of KERN are amazing. The electro-chemical surface treatment incorporates microns of rough ceramic onto and into the rim the rim surface improving dramatically the grip with the pads. The lifespan of this 2000HV ceramic is extreme, it saves the aluminium structure from the braking wear.

The rim dimensions are 24mm high and 20.5mm wide, with 16.5mm internal width. This makes the KERN an ultimate alloy climbing wheel with excellent clincher fit for reducing rolling resistance.
