JB asked about the differences in size and weight between the Litelok X1 and X3, helpfully answered by someone with access to Google.
By way of additional help, here are pictures of four reasonably popular locks. They are:
The X1, the X3, the Kryptonite ‘New York’ lock and an Oxford ‘Boss’ disc lock.
As you can hopefully see:
A. The X1 and X3 are pretty much similar in size, the X3 being slightly larger and, shall we say, a bit more ‘robust’. It is certainly heavier. That does not make the X1 bad, per se.
B. The Oxford disc lock is smaller (unsurprisingly) and considerably lighter. It is though, still a good lock.
C. The Kryptonite lock is somewhere in the middle. Larger than the Oxford but pretty much the same weight as the X1. I wasn’t sad enough to get the scales out. Those who are troubled by such things can Google it for themselves, hopefully.
What is best?
I have used all three at various times and still have my bikes. On a very unscientific measure, that makes them all equal and satisfies the oft heard “My bike has never been stolen” pumped out on these pages, sometimes with the additional “…. And I leave my keys in it”, as if suggesting that doing nothing is the best (and all) that any bikermate can do. It was from this that the ‘Pound of butter in the fridge’ was born.
Either and all of the three locks are easy to use and are pretty much impervious to weather. The easier they are to use, the less excuse you have not to use them.
The two Litelocks have a possible advantage in that it’s often possible to secure a chain as well. You might though need to cut down the rubberised cover of the D-section a bit (it’s only cosmetic) if the chain has narrow links.
My appologies for not including a banana by way of scale.
