On my PC now so will add a bit more…
Basically I had a new warranty one I bought secondhand, having previously had mixed reliability from them – but they do feel soooo good and the climb switch is the best in the biz.
It lasted about three or four rides, failing in Finale Ligure.
When fixing it up Dave at TF Tuned (the CC expert there) had a theory that the transverse mounting on the Process may have made the bladder more likely to fail by moving its position in relation to another part on the inside of the can.
I know they can last OK but I’m not going to take the chance again.
PS. I’d take anything about “blue seals” or whatever as hypothesis and Chinese whispers.
