What rim tape do you use for high pressure tires ?
 

I've only recently begun experimenting with some of the HP tires
available these days, and have experienced a couple of flats due to
deformation of the rim tape/strips. The most recent happened
overnight in the garage when a 140psi Vittoria bulged the tube
through an Open Pro rim spoke hole, right through the official,
brand new, Velox cloth rim tape and hit the spoke end. I rode that
wheel 50 miles at pretty good clip the day prior, so I'm happy it waited.:D

Anyway, what are the rest of you people using to prevent this
from happening ??? Are you going two layers ? Is there an effective
lightweight solution for this ? I've also experienced the plastic rim
strips deforming and/or sliding to the side just enough to fail.

Thanks for advice and opinion............

140? To What pressure are you inflating, normally?
Velox not adequate?
Try a combination of glass fiber reinforced packing tape ,
and a stiff, fused loop plastic rim strip. or apply the Velox
over the top of the fiber reinforced packing tape.

You might have a look at Velo plugs. I installed these in the a couple of wheelsets. I think it's a great alternative to rim take, but they won't work on Open Pros. They are intended for single eyelet or rims with no eyelets.
