So you decked yourself out with a proper, serious bike lock-- one that you can really trust to keep your ride safe when you stop for pints at your favorite dive bar, but now you're facing the dilemma of how to carry it around with you as you pedal from pub to pub. Kryptonite thought of it all with the Transit Transport-R Chain Bag, built to carry your big and burly chain from one stop to another without getting in your way or complicating the ride. The Transit Transport-R Chain Bag is designed to work with an array of bike locks with its spacious pack, and secures to your bike with 5 hook-and-loop straps. It zips open three-quarters of the way on the side so it's easy to pack up and unpack, and weighs just over half a pound, so while your chain might add weight to the ride, it's designed to keep its weight contribution minimal.
