I carry this in my tool bag:

Unior 1669/4 2 in 1 pocket spoke and cassette lockring tool

It works OK with 3.3 mm nipples, especially in a pinch - and can also remove and tighten a cassette lockring.

Quoting myself again. Talked it over at the bike shop today and determined that it was the crank arm that stripped out, not the bottom bracket.

Yea, that’s going to happen. A loose square taper crank is basically a ruined crank. Do yourself a favor and use a torque wrench to make sure the bolt won’t come loose (35 to 45 ft-lb). Also replace your crank bolts with ones that use an 8mm allen wrench to tighten. At least then you can carry the right tool to get you home. You’ll probably still have to replace the arm but at least you can finish your ride.

Lots of really good ideas here, especially from [MENTION=21724]cyccommute[/MENTION]. What's a film canister? Just kidding. Did you find the lockrings came off many various freewheel brands? I saw it only on the SunTour freewheels. Damn pain in the butt.

I remember those! Nowadays, I save old pill bottles for anything that use to need a film cannister.

I have a treasure chest filled with film canisters buried on a desert island. No, I won’t share the map:rolleyes:

The freewheels I had the problem with were Suntour. I learned to hate Suntour freewheels for various reasons, of which that was one. I went through so many freewheel removers with those damned freewheels as well as getting really good at destructive removal of them.

On my touring bike I carry a couple of FiberFix spokes, then I don't need a tool to remove the rear cluster with.

I keep my bikes up pretty good, I haven't had a breakdown for a very long time, maybe 25 years ago. I wasn't watching where I was going closely enough and hit a stick that was sticking out, my front wheel hit it and broke a spoke on a 36 spoke rim, the rim had just a slight wobble, I adjusted it back to like new and rode home. That was the first time and the last time I had to use a spoke tool while on the road.
