The Rema tip top kit let me down big style and the co2 canisters are useless. West Coast of Scotland, no phone signal, puncture. Fixed it with the kit, 1 mile later its flat again, second patch and last of the co2 and it went down again. Boshed a can of tyre seal in and it went down again.
10 hours later I'm recovered back to Leeds.
Sticky string is where its at, I had a hole in the back tyre big enough to put my finger through on top of the hardknott pass, I wedged 3 bits of string in it and it got me home. (not recommend but worked)
Compressor wise I stripped the plastic case off one and the internals were small enough to go under the seat.
