Hashtagg ISIS Cranks

Description

The Hashtagg ISIS Cranks are lightweight, high-performance crank arms developed by the innovative French brand Hashtagg. Originally inspired by the successful Hashtagg BB30 crankset design, this version has been re-engineered to work with standard ISIS bottom brackets, making it compatible with most modern trials setups.

Forged and then CNC machined, the cranks deliver an excellent balance of weight, strength, stiffness, and value. Large cutouts and recessed sections on the outer profile and rear face significantly reduce weight, while integrated strengthening ribs maintain durability for demanding trials riding.

The cranks feature a standard 1.37” x 24tpi thread, compatible with most threaded sprockets and freewheels. A wide 13mm threaded section allows you to run a bashring together with your freewheel or sprocket setup.

With a 35mm offset, these cranks provide generous frame and tyre clearance, ensuring compatibility with modern trials geometry.

Finished in a stylish anodized silver with clean laser-etched Hashtagg graphics, they offer a premium and minimalist look. Please note: the latest production version may not feature the large side logo shown in some earlier images.
