• I bought a pair of GP5000TL this week, and mounted them on a set of Kinlin XR31T, with tesa tape. Genuinely was easier than fitting tubed tyres, I'll totally astounded. Even went up with a normal pump and tyre pressure is exactly the same this morning. If they're as fast as they're meant to be I'm a total covert.

    Regarding a repair kit to carry on regular rides - is it worth taking worms etc, or should I just carry a spare tube in case of large punctures and hope the sealant closes up small ones?

  • I carry both a tube (Tubolito, with special tubolito patches too) and mini-worms and insertion tool (might double as a stabbing tool in a pinch) but I never had success with the worm stuff, even in controlled/home conditions. The worm would go in but pop out after a while due to pressure, or I trim the remaining part way too much and the tyre blows up in my face with sealant.
