Fixed gear cog(7 posts)

I want to make my single speed into a fixie. I have a Campy Record freewheel hub, so the cog will thread onto that. Any secrets to keep it from comming off, other than buying a track hub? I have heard about using red Loctite. Any experience or help is welcome.

What I do I my non-lockring side of my hub for a fixed cog is to grease the threads and put it on. The force from climbing one hill or a hard acceleration will get the thing on there damn good. But if you want something to hold it on, go yo your LBS and ask them for a old BB lockring, same size and threading as the hub.
hope that helps
Yeah it worksJack S

I've used blue loctite- on an old BB lockring, not the cog itself. I marked the cog and ring so I could watch for any uncscrewing, and it held fine. But I didn't like the messed up chainline that you get with FW hubs.
I use the same hub on my fixedStraightblock

and found there wasn't enough thread length on the hub to use a lockring. I've been running with no lockring or loctite for years with no problem, but I use 2 brakes, too.

That's weird... I used a 7-spd Campy Chorus and had enough room for cog and lockring. I guess it depends on thickness of your cog/LR.

Record high flange from the early to mid '70s that started life as a 120mm 5 speed hub. Barely 2 threads show outside the old SunTour track cog, and that's probably all they had room for with the narrow spacing. The high flange record hubs are a good match for my vintage track frame; they look like the Record pista hubs of the same era except for the oil cap, and the QR axle means one less tool to carry on the road.
