Straightforward and reliable with a 4-digit combination chain lock made of sturdy 3mm thick steel links and covered in a protective woven nylon sleeve to help prevent against frame scratches and rattling.

Weighing only a little over 1/2 a pound the 3 foot chain lock is a relatively lightweight security option that provides a step above basic theft protection while easily fitting into most saddle bags for storage or is unobtrusive enough to be left wrapped around your frame or seat post.
