• Rotor 3D30 Road Crank

Rotor offers the 3D30 crank as an upgrade from your standard crank, but without all the weight-shaving tricks of the 3D+ design. So you get all of the benefits of the thinking that went into 3D+, but save a bundle at the trade-off of 64g and fewer crank length choices. This crank will work with just about all modern bottom bracket standards, meaning that whatever bike you have today, whatever bike you might want tomorrow, you can use this crank, so long as you get the proper Rotor bottom bracket and install the proper spacers, which come with the crank.

The crank is light thanks to several factors. First is the oversized 30mm bottom bracket. (Yes, it will fit on bikes with threaded bottom brackets). Oversized is both stiffer and lighter. Second is the choice of drilling and milling the arms to remove excess weight. The interior possesses Rotor’s Trinity Drilling System, which means that each arm has three hollow channels running the length of the arm. The material and shape make the arms stiff, and the careful drilling makes them light. The cranks weight 532g with 175mm arms and 130mm spider.

As mentioned earlier, this crank works with any bottom bracket. Rotor calls it the UBB, Universal Bottom Bracket, System. Rotor has designed their own BB’s, which allow you to install this crank on English-threaded, Italian-threaded, BB30, PF30, BBright, BB386EVO, and BB86 bottom brackets. If you get this one crank, you can move it from bike to bike without regard to the standard the frame employs

The spider is a five-arm design, available in either 110 or 130mm bolt circle diameter (aka compact and standard). Obviously, these spiders will fit Rotor Q, QXL, and NoQ chainrings. They should also fit appropriately-sized 9/10/11-speed rings from their competitors.

The Rotor 3D30 Road Crank comes with the fixing bolt and all the spacers necessary to get this crank onto any of the bottom bracket standards it is designed to work with.
