OLSEN Singlespeed Direct Mount Chainring 31T Stainless steel

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

This will fit SRAM Direct Mount Pattern.

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 fit1/8""chains
• can be polished to a high shine
