We still mantain best features of E-Bones QRC: Lowest Q-factor, SSP, oversized bearings, sculpture machining and extremely lightweight.

QRC2 our new generation of road compact E-Bones bring SSP (stress split profile) concept to the extreme, they are stiffer lighter and slimmer!

Both cank levers have been designed for an innovative hyper sophisticate 3D cnc process that allows higher freedom on multidimensional shaping.
Bearing preloader allows an easy and perfect preload adjustment

Self extracting left crank: no special tools are required!

Hyper accurate Finite Element structure analysis minimizes stress concentrations and improves fatigue resistance.

Each crankset receives the same sculpturing, processing and care once limited only to prototype units.

Bearings: E-Bones come ready equipped with special bearings 6806 2rs (30-42-7mm). Our special bearings feature oversized balls, low friction seals and lighter weight.
Bearila E-Bones Rngs: E-Bones come ready equipped with special bearings 6806 2rs (30-42-7mm). Our special bearings feature oversized balls, low friction seals and lighter weight.
Hybrid Ceramic option is also available on demand (HybridUp W).
We warmly recommend to use the original bearing.
However bearing fittings on E-Bones can accept any standard 6806 2rs bearing.

Hours of state-of-art point-to-point 3D milling technology.

Stiff, light and slim!
