طبق قامه جاده Rotor 3D24 BCD110

With the 3D24 genes: the 3D24 crank from Rotor

The 3D24 crank impresses with forged quality and CNC-milled precision. With a 24mm axle diameter, UBB30 technology and TDS Trinity Drilling System, the 3D24 offers the perfect balance of weight and rigidity. The BCD110 Spider allows a wide range without sacrificing rigidity.

technologies:
Alu 7075
The Aerospace Aluminum Alloy 7075 offers outstanding physical properties for the construction of parts such as Q-Rings and REX 3 and 3D24 cranks.

TDS
Rotor CNC cranks are stiffer than the competitors’ cranks due to the Trinity Drilling System (TDS). In this procedure, three full holes are drilled from the bottom bracket to the pedal. This creates a box-like grid, similar to a box girder bridge. As a result, the cranks are extremely stiff and still lose weight, whereby an outstanding relationship between stiffness and weight is achieved.

UBB system
The UBB System (Universal Bottom Bracket) allows Rotor to use both 24mm and 30mm axle diameter, making it compatible with almost all frames on the market.
