Ultra tough U-lock
Quality, dependable U-lock
Inexpensive but effective security anchor
The Granit X Plus is a long time favourite in Cycling Plus tests. It has a very usable size and a reasonable weight, and a simple but clever bracket is included too.
The toughest chains we've ever tested
Simply put, anyone out there looking to make a cable lock that works should take a close look at the Steeloflex. This has a tough, armoured steel lock mechanism with folded and overlapped individual links that are over 5mm thick.
Security that wont break the bank
Convenient cable protection
Great value security
The first thing you notice about this über chain is the price, yep £125 is a whole heap of cash (though a 1m long version is available for £99). But for that you’re getting a whole heap of lock; very weighty yes, but strength-wise it’s simply one of the best.
As mentioned previously, mini U-locks make sense; a smaller shackle makes them very difficult to lever, or indeed to get any sort of levering tool inside the shackle. The downside is that it limits the applications, and the convenience of the smaller size is offset by the need to use a secondary cable (although that's something we recommend anyway).
The Pitbull sits second in the OnGuard range below the Brute and above the Bulldog, and although the lock barrel is more substantial than those below it, the shackle remains the same 16mm diameter.
Trelock have had a reputation in previous tests for building tough locks. This new MS650 is aimed at both the bicycle and motorcycle market and it is plenty tough enough for both.
The Paramount Plus is Squire's premier bike lock, "designed and aimed to prevent the most severe attacks".
Surprisingly comfortable way to carry a heavy chain lock
