For Sale: Corima 4 spoke

There is a screw on adaptor which is supplied by HED and some guy on evil-Bay, but they dont work. Although they come with a lock ring to secure the cog to the adaptor body, the adaptor itself is not secured to the wheel thus if you execute a skid, it still unscrews itself. Thus " to convert these to fixed just takes a bit of time." doesn't really tell the whole story.

If you are making the conversion permanent you can drill and tap the adaptor and put a grub screw into it to stop it form unscrewing.

you can also put some locktight on the thread and then tighten it with a spanner and extention pole giving you enough toque to tighten it more than the toque produced by a skid.
