The 3D continues to lead the 24 mm crankset market in terms of technology, performance and rigidity. It is Rotor’s most lauded crankset, having helped athletes that rode it to win three grand tour jerseys (Yellow, Red and Green) and no less than 15 UCI elite world champion titles.
The 3D’s UBB24 axle is compatible with almost all bicycles on the market, irrespective of their BB type. But the qualities of the 3D’s don’t end there; the 3D is one of the most intelligent external bearing cranksets on the market.
Universal Bottom Brackets
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.
