I use park glueless patches as described in earlier posts. They work well temporaily. Later (at home) I replace them with REMA patches. I sand/clean the area, apply a thin film of REMA cement, allow it to dry to tackiness (3-5 min.) and apply the patch.

I have never had a REMA patch fail. They're from germany and used to be available all over the place. Now I buy them in a box of 100 for $14.95 and a can of glue for $7.95 at biketoolsetc.com - They're located in Oregon and have great customer service.

I use these patches on everything from MTB tubes inflated @ 45psi to road bike tubes inflated to 115psi.

I live in Idaho, land of the famed goathead thorn and I fix a lot of flats on the family fleet of bikes. I highly recommend REMA patches. They have transformed my life.

This is been a paid infomercial for REMA patches... The facts are true - the names have been changed to protect the innocent.
