29er slime tubes is all you need.
I second Chongoman's idea. I did that with my commuter bike with shrader tubes and no issues on canal riding with road tires.mattKHS said:good idea chongoman. i may look into those. I am wondering if the perforance tubes i used this weekend to repair my flats were old too. i cant tell you the last time i bought them, so the splitting seams could have been an age thing too.
