Weight is the honest measure of how much steel a lock actually carries · review
The longest folding lock at the entry price here, at 94 cm (37 in), with 5 mm (0.20 in) alloy links and eight rotating joints and a frame bracket included.
Our conclusion The reach-per-euro choice. Take it if the problem you keep hitting is stands that are too thick to get a D-lock around.
Toptrek’s folding lock is the cheapest way into a lock format that actually solves a geometry problem.
Five millimeter links in a high-strength alloy, described as resistant to cutting and shearing, with an outer layer intended to protect frame paint. Eight joints, each rotating through 360°. Unfolded length 94 cm (37 in). A double-sided B-class cylinder with milled teeth on both faces. An adjustable-diameter bracket for a range of seat tube sizes, plus a one-year warranty.
Ninety-four centimeters is a lot for a folding lock, and it is the whole argument for this one. A D-lock secures a frame and a wheel to a slim stand and stops there; at 94 cm (37 in) you can go round a thick post, a wide railing or an awkward municipal stand and still get the frame and a wheel inside. That is a real category of parking spot that a D-lock simply cannot use.
At 5 mm (0.20 in), the links are thinner than the folding locks above it in this hub, and the cylinder class the maker states is not tied to a named independent scheme. Toptrek describes the lock as resistant to cutting and shearing; that is a manufacturer statement and we report it as one.

The manufacturer states 94 cm (37 in). Only the TITANLOCK in this hub is longer, at 100 cm (39.4 in), and it costs around three times as much — so this is the longest reach available at the entry price.
Yes. The manufacturer supplies an adjustable-diameter bracket described as fitting a range of seat tube sizes without damaging paint.
