Delivering magic to the masses.

By now, it's a fact that 11-speed is here to stay. And as we all know, SRAM's innovative spirit and technical know-how is what brought this technology to fruition. Now, SRAM has opted to spread the magic to the masses with, well, a little more affordable price point. So, if you're in need of embracing the latest-and-greatest, but you want to pick out a tooth-count that's specific to your needs, the new SRAM X01 BB30 Crank Arms are for you.


It's a direct contributing factor to the carbon GXP Crank Arms comfortably weighing in under 700 grams with an X-Sync chainring, while still remaining incredibly strong. The arms are mated to an aluminum spider for a lightweight system that doesn't require a finessing of parts in order to make an optimal single-ring setup. The highlight of this component, however, is the X-Sync chainring.


Given that ring size is highly preferential, we've decided to offer the arms without the chainring. But, when you decide on your ring of choice, we guarantee that you won't be disappointed. Designed for maximum chain control, each CNC-machined X-Sync tooth supports inner- and outer-chain links. The machining process results in a variable thickness from tooth-to-tooth, so the chain and chainring essentially lock together as you pedal. However, the locking of the two doesn't inhibit efficiency, and it eliminates the common ailments associated with a single ring.


The SRAM X01 BB30 Crank Arms use SRAM's Gutter Seal design to cut friction and to ensure a long lifespan. The arms are available in either a 170 or 175mm length and in the colors Red or Black. Please note that the X01 chainring is sold separately.
