Why don't splined hubs exist (or do they)? Wouldn't this solve the problem of stripping your hub and having to mess with a lockring? I know they make sprockets for retrofitting shimano hubs and such but I have yet to see a splined track hub. Anyone got any info?

level hubs use bolt on cogs and some folks have drilled bmx splined cogs to fit the disc side of single speed or front disc hubs.

skidding is not necessary in the velodrome, so it's not really a problem that most manufacturers care about...

edit: oh yeah, miche makes splined cogs that fit onto a splined carrier that screws on where the cog would go on a track hub. it would still cause stripping from skidding like underwear. underwhere?

if you are quite concerned, you could try using the miche splined adapter thingy. just locktite it on, and switch out cogs whenever you like. of course, you are stuck with miche cogs.

^ and the splines on the miche adaptor do eventually wear out, leaving you with slop in your drivetrain.
It needs to be replaced every so often. Don't locktite it on.

Or we could all just remember to grease our threads and keep our lockrings tight.

Another option, especially for offroad fixes, is the disc-adapter. Boone and a couple other folks make cogs that bolt onto the disc brake interface of MTB hubs, thus running your bike as a fixed gear. Alternatively, you can just drill a cog of some sort to fit.

It might be possible to do this with disc road hubs (for non-MTB spacing frames), but I don't know of any that have the 130mm or smaller spacing.

Stripping hubs is only a problem if:

a) for some reason you install your cog/lockring incorrectly.
b) your hub is complete crap.

It should be simple to avoid these problems.

Or is you use really delicate parts designed for an indoor, smooth wooden surface on the streets. Skidding and skipping on equipment not designed for it is also another way to strip a hub.
