Our new generation of road compact E-Bones bring the SSP (stress split profile) concept to the extreme: they are stiffer, lighter and slimmer! Both cankarms have been designed with an innovative hyper-sophisticated 3D cnc process that allows higher freedom in multi-dimensional shaping. Bearing preloader allows an easy and perfect preload adjustment. Self extracting left crank: no special tools are required! Hybrid Ceramic option is also available on demand (HybridUp W). However bearing fittings on E-Bones can accept any standard 6806 2rs bearing.
