Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Cog keeps slipping

Hello

I'm having troubles with OnOne hubs and cogs (these are made in Taiwan and sold in UK under the OnOne name).

Cog keeps slipping during skid, I used the shimano whip for cog and lockring



I even rotafixed the cog on the hub and used a small spacer just to be sure that the lockring was pressed hard on the cog without result.

Maybe the hub is defective?

On-one hubs - they look identical to dimension hubs. The solution to your problem is to use rotafix on the cog and then get hozan lockring pliers and really tighten the lockring on.

It also helps not to use cheap cogs/lockrings. It also helps even more not to have a spacer on the lockring (why?). Less thread engagement on the lockring = bad.

The other solution is to get a brake and stop skidding.
