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".

The Blok CH X300 from Raleigh is in fact a re-branded Magnum, but with a padlock we haven’t seen on others from the Magnum range.
The BS510 is Trelock’s top of the range U-lock and although outwardly very similar to the 400, the extra 500g in weight tells you that it’s not fashioned from the same stuff.
The MS 405 is another hefty lock, and with the combination of padlock and chain just shy of the 3 kilo mark, it’s not exactly lightweight carrying material.
For the new 2005 model, the New York saw the introduction of a new fl at key lock mechanism over the previous cylinder-style lock, while the dual deadbolts securing the shackle to the lock body remain.

Masterlock’s funky Streetcuff design has been around for a couple of years and the design has been tweaked and improved strength-wise in that time. The police cuff style remains the same, but it’s good to see that it now comes complete with a neat bottlecage boss mounting bracket.
The Masterlock Streetcuff takes a novel approach to the bike security problem. Using a hardened laminated steel construction, each cuff has an internal diameter of 3in - enough to lock the front wheel to the down tube using both cuffs, but not the rear wheel to the frame using just one.
Horseshoe style locks are generally favoured on continental style roadsters or shoppers whereas in the UK cable locks are the norm - so why not get the best of both worlds?

A 2m long armoured cable with a 30mm diameter for £25 sounds good value; almost too good to be true. Sadly that’s exactly how it proved to be.
The Zenith Link occupies the middle ground between a big tough chain and a cable lock offering hard 8mm links, but with an integral lock rather than a separate padlock.
No real security
