I have sets of the new tubeless ready Zipp NSW wheelsets in 404 and 808 depth. Has anyone seen any comparative data on Zipp's own Tangente Speed tubeless vs the new GP5000 tubeless? Does anyone have any experience running the 5000TL with Zipp NSWs? Does the combo work well?
I've been training on my 404s using Zipp's Tangente Speed RT25s with good success. Several hundred training miles on mediocre roads. No flats yet. The ability to run 10-15 lower PSI make a bigger differnce in comfort and grip than I expected. I like it.
So I'm thinking of going tubeless as well for my 808 race day wheels, which are currently running Attack/Force. I'm debating between the Zipp and GP5000TL tires. On one hand, I'm thinking go Zipp / why mess with a good thing and combo is working well. On the other hand, am I leaving a few watts on the table by not running Conti's latest/greatest?
I have experience with the 303 NSW which has a larger internal rim width designed for 28c tires. First ran the Zipp Tangente Speed RT28. These mount up great and rolled good. Speculation online is that these are made by Hutchinson for Zipp as they list Made in France.
Next ran the Schwable Pro One 28c. This tire also mounted up great and has proven performance. I've also been running this on a set of Enve SES 4.5AR's with good success.
Recently switched out the Pro One for the GP5000TL. Mounted up great and rolls well. Not a lot of miles yet.
Going from BRR testing the 5000TL rolls 2 to 3 watts better than the Hutchinson Fusion 5 Galactik TL and the Schwable Pro One.
For straight-up TT's the Corsa Speed TLR would provide a bit more speed with the downside being durability. I have run this tire with latex at 70.3 distances with no problems.
