I've been getting a lot of flats recently with tubes from
Performance (700x19-25c, Presta valve). They seem to get
flat in the same place every time--about 4 spokes away from
the valve--yet I can't find any defect in the tire or rim
that would cause a puncture.
It always looks like the tube material simply separates and
forms a hole. If I partially inflate a new tube, I don't see
any defects, but after a few rides, I get a flat. I normally
inflate the tires to the recommended 115 psi. So, I'm
suspecting a quality control problem that might have caused
a bad batch of Performance tubes.
Can anyone recommend a more reliable brand of road tube? I'm
using a set of Avocet FasGrip K20 700x25c tires (well-worn,
which I suspect doesn't help the tubes last any longer).
