Thats the Plug'n'Patch that was mentioned right above...and they are great....but I am stil not keen on patching a Cycle tire. I have used and installed many a Plug'n'Patch in my day....and when put in right, they hold up great....but with that said....thats alway been in a car/automotive tire. I am sure it would hold up just fine...but there is always that slight chance.
