Description

The United Rotary sprocket is 3D CNC machined from 7075-T6 aluminium, with the logo and the tooth count machined into the face.

It measures 6.35mm thick with a 23.8mm centre bore, so it suits cranks with 19, 22 or 24mm spindles. Sizes run 25t, 28t, 30t and 33t, in black, polished or raw.

Features
  • Fits 19, 22 and 24mm spindles. The 23.8mm centre bore covers all three spindle sizes, so you do not need a new sprocket if you change cranks.
  • 3D CNC machined 7075-T6. Cut in 3D from 7075-T6 aluminium rather than pressed from flat plate.
  • Four sizes, 25t to 33t. Choose 25, 28, 30 or 33 tooth to set your gearing, at 70g, 85g, 87g and 90g in order.
  • 6.35mm through the face. The sprocket runs 6.35mm thick, so you know exactly what you are bolting between the crank arm and the chain.
  • Size machined into the logo. The CNC machined logo carries the tooth count, so you can read your gearing off the sprocket later.

  • Spindle: 23.8mm centre bore, compatible with 19, 22 and 24mm spindles
