Trelock 8004815 Rs 453 Protect-o-Connect Balloon Az Frame Lock, Black, Standard Size

Good solid lock. Now I combine it with a flexible chain and the bike is doubly well protected.

The lock is fine, but there are quality defects in the brackets that need to be attached to the frame. The screws for attaching the "bands" are plastic. Careful handling is required, as they can over‑tighten quickly. Metal screws would definitely be a better option.

A bit fiddly to assemble, but otherwise flawless

From my experience with my previous wheel with this lock, I was able to access it again. It's practical to have the option to use a compatible steel cable or chain. Easy to attach to the bar and gives a solid, high-quality impression.
