Walmart was selling foam inserts that would replace the tube. This would eliminate any chance of a puncture. The disadvantage was weight. The one I handled was about 50% heavier then a convenrtional tire and tube.

A more puncture resistant tyre isn't going to necessarily help in this situation. If you've come out of work and you've got a flat, it seems like a slow leak. If you didn't find anything in the tyre the 2nd time, I would be checking how you've seated the tyre on the rim, have you accidentally pinched the tube a bit, are the valves in good working order, are ...

There are a few things to do. I'd start by reading this link from Sheldon Brown. 1) First determine how the flats are occurring. Inspect the tube. Is the rim tape on the rim properly? (if not, you'll see a puncture on the wheel side) Is the tube being pinch flatted? (a snakebite flat, two very closely placed punctures - usually a sign of too low pressure) ...

1) Check and double check for objects in the tire again. Little shards may be completely embedded into the tire. I once had to go through 3 flats, searching every time, before finally finding the little bastard. Bending the tire inwards might help. 2) The Smart Sam exists in a "Plus" version with a 3 mm puncture guard. So if you like the Smart Sam, check ...

Friction shifters have no clicks. If there's chain rub, simply move the shifter a little.

I had similar problem with a tube of super glue. My mother-in-law suggested that I put the tube in the freezer. I actually store the tube in a glass bottle and close the cap - to avoid contact with food. The glue never dries up. You can try the same with your glue.

You could try adding sealant to your tubular tire. Tufo Tire Sealant, Stans's No-tubes (and other tubeless sealants) can be used to deal with small punctures. Most recommend not using the sealant as a preventative measure, but more so as an after the fact solution to quickly fix punctures on the road. However, Tufo Standard tire sealant says that it can ...

I broke a front derailleur cable at the top of a long climb once, leaving my chain stuck around the little crank for the descent. Luckily, I was able to find a small, flat-ish rock on the side of the road that I could wedge between my frame and derailleur in order to hold the chain up on the big crank. The rock shook free once or twice on the way down the ...

If the cable breaks at the shifter and you have externally-routed cables, here's what you do: Hand-shift the bike onto a big cog on the rear by pressing on the derailleur as you spin the pedals. Tie the cable around the front cable stay on the downtube. Adjust as necessary to get the bike to hold a gear.

"Nothing is so broken you cannot make it worse" - breaking a perfectly good chain in the field, miles from nowhere, with a light weight emergency tool, would be my very last resort. This will only work if the broken end is not too frayed. Remove the cable completely from the outers and the shifter. Thread the cable though the barrel adjuster on the ...

They certainly are, and you have different alternatives depending on how much cable you where left with and the available tools. If the cable snaps towards the middle of a sleeve-less section (i.e. between cablestops in the frame) you may be able to tie a piece of wire. This will give you some shifting posibilities but don't espect full functionality, ...

In the method Pete suggests you don't pick a sprocket as you don't have a horizontal drop out. Go small up font and a middle in the back for chain alignment and pick the best chain length. From there you may need to go up or down one in the rear to get chain tension. Is not going to be perfect. But tension and alignment is more important than the exact ...
