OLSEN Singlespeed 18T Stainless steel 9Spline Sprocket

At OLSEN HQ after many years of destroying drivetrains I have developed the following FLAT ROUND chainrings and sprockets for singlespeed use.

This sprocket will fit any Shimano HG cassette freewheel.

WHY?

  • Normal "gear focused" chainrings do not last.
  • chainrings are expensive
  • chainrings wear out.
  • every gear feature adds cost.

FLAT and ROUND

  • No post machining.
  • No "OVAL" or BIOPACE Cogs designed by marketing departments.
  • Lasercut in the UK from 3mm 316 grade stainless steel.
  • 3mm will fit 1/8" chains
  • can be polished to a high shine
