OVERFAST FACTOR ONE Battery Holder / Cover

OVERFAST Carbon Battery Holder for Factor ONE

Small Detail. Properly Engineered.

The OVERFAST Carbon Battery Holder is a dedicated lightweight upgrade for the Factor ONE, designed to securely locate the Shimano Di2 battery or blank it off for SRAM AXS Groupsets while reducing weight and adding a distinctive finishing detail.

Available for both Shimano and SRAM, with each version developed specifically around its application rather than adapted from a universal design.

Lightweight by Design

Despite its small size, considerable development has gone into the design.

Multiple iterations were used to optimise the shape, maximise the cut-outs and remove unnecessary material, with reinforcement added exactly where the component needs to handle load.

The result is an exceptionally lightweight component:

SRAM: 2g
Shimano: 6g
Weight Saving: Up to 4–8g compared with the stock component

Three Carbon Finishes

Available in three distinctive finishes to complement different Factor ONE builds:

• Forged Carbon
• 3K Twill Black
• 3K Twill Silver

The 3K Twill Silver offers a particularly distinctive finish, using a style of carbon fibre rarely seen on cycling components.

Compatibility

Frameset: Factor ONE
Drivetrain: Shimano or SRAM
SRAM Weight: 2g
Shimano Weight: 6g
Finishes: Forged Carbon / 3K Twill Black / 3K Twill Silver

A small component, engineered with serious attention to weight, fit and finish.
