Race Cranks vs. NoBoss Cranks


The only difference between Profile Race Cranks and Profile NoBoss Cranks is the method of attatchment of your sprocket. Race Cranks use a sprocket bolt, and NoBoss uses the 48 splines on the bottom bracket spindle to mount a Spline Drive Sprocket or Spider. Otherwise, the crank arms are exactly the same- same tubing, same q-factor, same limited lifetime warranty. A complete set of NoBoss cranks and a Spline Drive Sprocket is going to be slightly lighter than a comparable set of Race Cranks with a similar sprocket.

With a Race Crank and a traditional bolt on Sprocket, the pedal power is transmitted to the chain via that sprocket bolt. With the NoBoss cranks, the entire sprocket is transmitting power through all 360 degrees on the 48 splines of the BB spindle, the same 48 splines that are used to locate the crank arms.

  • 175mm NoBoss Arms with CrMo 5 5/8" spindle, CrMo Crank Bolts, 25t Spline Drive Sprocket = 30.6oz (866g)
  • 175mm Race Crank Arms with CrMo 5 5/8" spindle, CrMo Crank Bolts, CrMo Sprocket Bolt, 25t Ripsaw Sprocket = 31.3oz (888g)

For BMX Freestyle, there are several advantages:

  • Weight Savings
  • Left Hand Drive and Right Hand Drive Compatible out of the box
  • Clean Styling

For BMX Race, in addition to the above:

  • Stronger, more secure power transmission due to entire sprocket/spider transfering power, rather than one bolt on drive side crank arm

For Fixed Gear, in addition to the above:

  • The back and forth motion due to braking and accelleration of a fixed drivetrain loosens the sprocket bolt almost continually on standard Race Cranks. Eventually, the sprocket is damaged. With NoBoss Cranks and a Spline Drive Sprocket, this problem is eliminated.

14mm Fixed Hubs?


We don't currently offer a 14mm axle for Profile Fixed Hubs. Any of the axles we currently manufacture will not fit the Fixed hubs, either front or rear. We're working on prototype 14mm axles, however, and should have them out to the team in the next couple of weeks. We'll let them ride them around for a month or two, and if all goes well, we'll have them for sale by Interbike in September.
