The 311 design is based upon the following Criteria:
A handlebar must be stable.
The width must match the application and the anatomy.
The angle to the rear must be tuned to prevent hyper extension of the wrist.
The level determines the backrest angle.
The upward curve determines the elbow position, and thus the dynamics on the bike.
The downward curve lays the elbows to the body and determined the aerodynamics.
Hand - elbow - shoulder - back
The hand position determines the position of the elbow, this effects the load on the shoulder zones whose strength is determined by the back angle.
+ Width: 740 mm
+ Rise: 15 mm
+ Diameter: 31.8 mm
+ Back Sweep: 16°
+ Upsweep: 2.5°
+ Weight: 320 grams
+ Material: AL 7050
The outer diameter of the handlebar largely determines the strength. Thus the larger the outer diameter the more stable is the handlebar. This fact has driven the move to the oversized clamping diameter of 31.8 mm instead of the traditional 25.4 clamping diameter.
However, the increase in outer diameter size increases rigidity and ride comfort suffersy.
To prevent this the SQlab 311 MTB Handlebar is ovalized after the clamping section - this increases comfort and decreases the likelihood that the handlebar will break under extreme pressure.
