“TPU is the way to go, extremely light in the wheels but also to carry as a spare. Does lose a few PSI more then standard tubes as mentioned across various sites, won’t change from TPU”
“Saved about 60g over a butyl tube. Followed the instructions to inflate first to max 8psi and check for leaks (none), carefully installed and it’s been going well for over a week. Small and light. Pleased to be having success with the first TPU tube.”
“Punctured on second ride, I am really not impressed with TPU tubes.
The Exar Ultralight are the second brand I have tried, first brand the same thing happened, punctured after the second ride.
I have gone back to butyl tubes and haven't had the sme issues.”
