Welcome
If you have been searching for an easily available and beautifully engineered bolt on cog then the brand new londonfixie ISO-Cog is now available together with a range of custom parts.
Latest News:
Stocks of ISO-Cogs are again running low, currently all sizes are still available except for 1/8" 16t. Delivery date will be posted soon - much larger quantities are on the way!
Due to an improved finish we are no longer polishing ISO-Cogs as standard, however we are confident these are the very best and hardest wearing disc mount cogs available and are now guaranteeing them for life to the original owner (also applies to previous sales). Please see the shop for details.
Our new CNC spacers suitable for Hollowtech/splined/square taper bottom brackets or for spacing traditional screw-on fixed cogs are now back in stock. Please see this page and the shop for more.
