Rotor 3D+ MAS Crankset 160mm 110BCD

Increasing performance without adding any weight seems like a stretch for any manufacturer, but with years of experience within the cycling industry and a vast knowledge of CNC-machining, Rotor has managed to do just that with the Rotor 3D+ MAS Crankset 160mm 110BCD.

Rotor has managed to shy away from the rest of the market who are increasingly using carbon fibre within their crankarms, but Rotor has constructed their 3D+ MAS with 100% aluminium construction and 7055 alloy that’s lightweight, strong and stiff.

Even though the 3D+ is not carbon fibre, these cranks are still lighter than other high-end products thanks to their Trinity Drilling System (TDS) that withdraws any material that doesn’t add to the structural rigidity of the cranks. Trinity drilling puts three full-depth holes, but leaves behind a boxtrellised structure, resembling that of box bridges. In terms of the ride, this gives you a phenomenal stiffness to weight ratio for superb performance.

Rotor have even gone out of their way to make your life easier with the revolutionary aluminium UBB30 axle. This means you can upgrade a huge number of bikes with these 3D30 Cranks. Their compatibility covers BSA (68 & 73), ITA, BB86, BBB89, BB92, BB30, BB386 evo and BBRight bikes.

Another issue Rotor has overcome is that of balance. Twin Leg Concept (TLC) gives you the optimum in balanced cranksets. Furthermore, these cranks feature Appropriate Light Weight Material Application (ALMA) to keep them at an impressive 485g considering the solidity of the design.

Finally, they tackled the issue of getting your rings angled for your riding by coming up with the new Micro Adjust Spider (MAS). This features alternative bolt hole placement allowing for intermediate positions between existing OCP (Optimum Chainring Position) of the Q-Ring. A standard crank in combination with the OCP of the Q-Rings, allows approximately 5 degrees of adjustment. Using Q-rings with this crankset allows for half positions giving approximately 2,5 degrees. This means that you can micro-adjust the position of your Q rings, to suit your riding style.
