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).
E-Bones
W are avaiable for different BB shells.

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.
