E-Bones W from479g.

 

New generation E-Bones: a huge increase in performance and bearing durability.

Developed with our hyper-accurate dimensioning, they include our proprietary design:

Stress Split Profile

That means hi-torsional rigidity with unmatched weight.

How does it work?

Torsional and bending stresses are split into separate crank areas enhancing rigidity/mass ratio in every pedalling phase.

 

Weight: 498*g/set

Sizes: 175 or 172.5mm.

Bearings: external 30 42.

Spider: standard 104mm / 64mm.

Finishing: black anodized.

Q-factor: 160mm with BSA 68 BB shell.

Spindle: integrated 22mm axle.

Graphics: laser etched.

Option: Hybrid ceramic bearings.

 

* Cranks weight with complete BB assembly for BSA68 and BB30 model(see talbe below).

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

 

More than an hour of state-of-art 3D milling technology.

These 3D sculptures can handle your sprinting efforts like no other metal cranks,

SSP technology works for you!

 

New integrated design employes massive 30-42mm bearings (bigger than Shimano XTR). The external positioning enhances axle rigidity.

New bearings weight more than light-Isis ones but feature 50% bigger balls. 3.5mm balls can manage loads better and with much less sensitivity to lateral loads, water and dirt.

E-Bones: the most sophisticated crankset ever made.
