HASHTAGG BB30 Right Crank Arm + Axle V2.0

Description

Upgrade your drivetrain with the right-side crank arm and integrated axle from the latest Hashtagg BB30 V2.0 system. This updated version was engineered with a focus on increased stiffness, improved weight balance, and long-term durability—making it an ideal replacement part or performance upgrade for riders using a BB30-compatible setup.

The V2.0 revision features a reworked crank profile that shaves off unnecessary grams while enhancing rigidity under load. The axle has also been optimized to reduce weight compared to the previous generation without compromising strength. Milled from premium 7075-T6 aluminum using high-precision CNC machining, this one-piece arm-and-axle assembly creates a direct power transfer path that minimizes flex and improves pedaling efficiency.

Designed to fit standard 68 mm bottom bracket shells with a 1.37″ x 24T thread, this unit maintains the BB30 system’s hallmark simplicity: the right crank arm is permanently bonded to the 30 mm spindle for stiffness and weight savings. Smooth rotation and excellent durability are supported when paired with 42 mm external sealed cartridge bearings (not included).

This component is ideal for riders who need to replace a damaged crank arm/axle, build a lightweight performance bike, or refresh an existing Hashtagg BB30 setup.
