Titanium Spindle Radius cranks are next level.
The spindle here is an integral titanium spindle welded directly to the left cup, so eliminates the need for a bolt and bolt cover on that side. The right side crank has our normal spline to both attach to the spindle and drive our spline system. The titanium spindle option will be stiffer and lighter than the aluminum version. It is available in custom lengths. We will likely try to stock more common lengths such as 119mm.
The cranks have a titanium bolt cover only on the right side that also acts as a crank extractor when the included 8mm bolt is backed out. The bolt cover uses an oversized hex pattern that accepts the included hex 5/8" wrench stock. The bolt cover can be removed with a 5/8" or 16mm wrench, socket, or adjustable wrench. The large hole minimizes weight while allowing good torque.
Crank Lengths: The cranks are offered in standard lengths of 165mm, 170mm, and 175mm. We also can make custom lengths from 150mm to 180mm at extra cost.
Our unique drive spline is one that fits our direct drive chainrings, SRAM 8 bolt, spiders in 110mm 5 bolt, 130mm 5 bolt, or 104mm 4 bolt spiders, or our Adapt-R's to convert our original spline to other popular splines like RaceFace, SRAM 3 bolt, HollowGram, FSA, E Thirteen, Absolute Black, Wolf Tooth, Easton, Hope, and others. There are some good chainrings out there; this allows you to use the chainrings you have.
We have a preload adjuster for the left side and a spindle spacer kit for the right side to be able to fine adjust your chainline. The spacers are in 0.5mm, 1mm, 2mm, and 3mm widths so you can get any spacing between 0.5mm and 6.5mm.
