Trouser Bands (x2)

If you cycle in normal trousers, you'll know the problem. Loose hems get caught in the chain, snag on the chainring, or end up covered in oil. Weldtite Trouser Bands solve that in seconds. Just wrap one around each ankle and fasten it in place to keep your trouser legs clear of the moving parts while you ride. 

They're small enough to keep in a jersey pocket or saddle bag, so there's no excuse not to have a pair with you.
