Reddit mentions of Onguard Akita Loop Cable Lock (Black, 10mm x 4ft)

In addition to what others said, just do yourself a favor and buy a Camelbak.

Its nice to just have water with you all the time, and its easy to get dehydrated on a bike, especially what its hot. On a long tour, I like to have it just because I always know I have some water when I stop for the night and that kind of thing too. If I'm at a hotel, I fill it up and put it in the fridge overnight, and I'm good all the next day. I like this one because 1.5L is enough for a full day while still being light, and it comes in high-viz yellow.

For multi-day rides, I also recommend making yourself a little portable tool roll. Even if its just the common allens and the 2-3 most common wrenches for your bike, plus a pair of pliers and some zipties.

If you're on a GS, you probably have big luggage like me. I also bring a cable like this along with a padlock. This lets me lock my helmet and jacket to the bike if I'm going off to do something, and my luggage is already too full for that stuff. Mine is 4ft. Cable can just easily go through the chinbar of the helmet, long enough to just go through one of the arms of my jacket, and I can lock it to the bike with no fuss.

I have a U-lock also. I see the security of it and it's a dilemma for me too.

But because of the weight so far I've opted for using a cable extension to a cable lock similar to yours.

It aloud me to wrap around a tree at a campsite.

Just wondering what you thought.
