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.
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 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.
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.
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 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.
Out of the box the Magnum Plus cable looked to be a winner. With a Sold Secure Gold-rated armoured cable, a decent length and 25mm thickness, five keys included and backed up with a £1,200 anti-theft guarantee, we fully expected to have our work cut out for us.
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.
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.
Combination locks offer one distinct advantage in that being key-less there are no keys to lose. The Street Quantum from Masterlock offers a usable 1.8 metre length, plenty for wrapping through the frame and wheels of most bikes.
Padlocks and chains usually occupy the upper price regions, which is why when we saw the price of this chain we thought it was a mistake. Only on closer inspection did we see something was amiss: the padlock seemed impossibly light (less than half of the others on test).
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.
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.
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.
