Don't come back to your locked bike only to find a sad frame missing its wheels and saddle. ABUS's NutFix system protects wheels and seat posts against theft using a physical trick. Thieves don't know the trick, but you do, so you can open them with a standard wrench.

Seat post clamp locks include the post clamp as well as fixing bolt and nut.
