Which butyls u use that are close to latex? Would like to try them!

I switched to latex a couple of years ago and won't prob ever go back to butyl, as the positives far outweigh the (1) negative.

Having to put 10 to 20psi into them each day is a small effort when u consider how much better they roll, the added puncture resistant they are, and the fact that they tend to never go immediately flat when u do happen to flat. Nothing worse than the instant butyl flats at high speed, where latex will more often than not just slowly deflate, allowing for safe stopping (ESP on front flats).

FWIW I would take Mich ProRaces over the Contis every time ....

Are you sure about all that?

Very sure from my couple of years experience on latex

Because?

Because they wear and grip better that's why

My experience is different, and a fair number of people on this board with decades of experience riding would not choose latex tubes plus clincher tyres for the mountains. Likewise, some manufacturers of clinchers explicitly state not to use latex tubes with their wheels. I wonder why?

.....

I'll assume that's not a rhetorical question and venture an answer. It's because latex tubes are more vulnerable to heat than butyl and in clinchers the tubes lack the all round protection of tubs.

The best I've tried are Panaracer R'Air. I cleaned out the stock here in the states last year, and contacted the distributor and bought some of the last that they had as well (they were completely out of 60mm stems, which is what I wanted most, but still had a few 48s).
Still, I got enough that I should be good this year. These tubes can go three of four days without losing significant pressure and ride very close to latex. If I can't find them in the future, I might have to give latex another shot (but they better not loose more than 15 psi in 10 hours, or I won't like them).
