• 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.

  • trying to work out if 100g saving is worth

    What improvement are you expecting to achieve by reducing your load by 100g?

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

  • I carry them as spares, but haven't had to use one yet. Have a few from RideNow. I can't see why they wouldn't be work as a lightweight spare to get you home.
