On a plus side, it seems like a really well-built product.

They make the best, durable products.

and I will strongly recommend this product to anyone, any time

The Abus Bordo 6500 aka Granit X-Plus is a less common style lock, designed to be nearly as strong as U-Locks but without the limitations

would be that both old and current designs are much more flexible than any standard u bolt and more secure than most any cable.

Maybe not quite as secure as high U locks but certainly a lot more practical with the carrying case that can ether be strapped on or bolted directly to the frame where the bottle cage goes

I would feel confident in using this over those stupid clumsy U-locks which are so frigging huge and heavy (this is 4.4 lbs
