QRC-2 brings the SSP (stress split profile) concept to the extreme.

Stiff, light and slim!

 

Both crank-arms have been designed with an sophisticated 3D cnc process that allows higher freedom in multi-dimensional shaping.

Overall stiffer and stronger structure.

Self extracting left crank: no special tools are required!

 

Precise "click-dial" bearing preload system.

Bearings: QRC-2 come ready equipped with a variety of special ABI-enduro bearings (6806-2rs / 30-42-7mm).
On our web-shop you can select the bearing type that suits you
the most.
Choose among all-round, stainless, oversized balls or HDC Hybrid Ceramic moodels according to the intended use and to the environment of your area.

QRC2 accepts standard BCD 110mm chainrings and bolts.

We recommend OctaRamp chainrings for proper shifting performance, perfect cosmetic match and weight reduction.

Complete you QRC-2 with Extralite parts: OctaRamp RC2 / MC / CH2 and 1 set of ExtraBolt1 in your favourite anodized finish.

Hyper accurate Finite Element Analysis (FEA) of the crankset structure minimizes stress concentrations and improves fatigue resistance.

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

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