ABUS Granit X-Plus 540 USH Brkt 300mm LS Shackle U-Locks

When I bought this, I thought it was one of the best rated U-Locks on the market. Turns out that’s a slightly different Abus that doesn’t seem to show up on Amazon. Oh well. Still WAAAAY better than a cable lock.So far, no theft, so I can’t personally attest to the security of the lock. But I can tell you about the ergonomics: this thing is BIG. Which makes it useful for locking your bike up to non-ideal structures (the extra reach of the U is helpful). But it makes mounting trickier. If trying to mount it in the center triangle, it totally eliminates even being able to fit a bottle cage. There are a few ways to mount it to the side of the seat post, parallel to the bike, but those interfered with my rear-mounted kids seat. I ended up mounting it on the rear seat-stay, and it seems to be working nicely there.That being said, the mount that comes with the lock is MUCH better than the mount that came with a different U-Lock i purchased. It gives you a lot of flexibility in mounting options.Yes, this thing is heavy. But I don’t notice it, and you probably wont either unless you’re a pro racer.
