• Anyone tried the TPU tubes which abound on eBay etc? Would only be used in a tubeless emergency, but don't really want to carry an emergency tube which is no good. Just trying to work out if 100g saving is worth 25 odd quid price difference for something I (hopefully) won't use.

  • If you want faster than butyl get latex. TPU don’t deform so worse ride quality and much more fragile

  • Not about speed, it's just about having something to use if my tubeless setup fails and tpu take up a tiny amount of room compared to butyl.
