Code: 3D30

Super-compatible UBB30 technology

The 3D30 uses ROTOR’s ultra-rigid and super-compatible UBB30 technology (developed for the 3D+), offering an “indestructible” upgrade opportunity for almost all bikes on the market – whether they were designed for 30mm cranks or not.
 

The 3D30's cold forged, trinity drilled arms and aluminium UBB30 axle ensure serious rigidity and performance to face anything you can throw at it, while saving weight in regards to the majority of 30mm cranksets.

Bombproof design and reliability

ROTOR's bombproof trinity drilled crank arms resist bending and twisting forces better than classic hollow tube crank designs can. ROTOR’s crank arms are stiffer than the competitions forged products due to our Trinity Drilling System. This process drills three full-depth holes from axle to pedal, leaving behind a boxtrellised structure (similar to box bridges). This gives our crank arms superior rigidity and an exceptional stiffness-to-weight ratio.

It works with everything!

The UBB (Universal Bottom Brackets) system is not a standard; It’s all standards. It allows installation of almost any 30 or 24mm axle crank from ROTOR on the bike you have, regardless of its BB type. ROTOR’s “UBB” super-standard encompasses all BB standards.

Solutions. That’s probably the best word to describe ROTOR’s design philosophy. We identify performance problems and set out to solve them, resulting in improved & optimized products.

This offer includes the Rotor 36/52 chainrings and a free PF30 bottom bracket. Will fit all other frames with the correct BB see PDF guide in link below.

General information about our shipping
Great product. I already had 53/39 Rotor cranks on my Cervelo so knew what to expect. This awesome price made it worth getting a complete set of compact cranks instead of just the spider and chain rings.
Superb product and at half price this is amazing. Lovely engineered and machined helps to keep the weight down and it'll look great on my new BH frame. Included a bottom bracket which makes it brilliant value.
Very much impress on this product. Very light!
