Have you had a chance to try these tires? What do you think of the concept?
I just sent Bontrager an email asking them to send you pair so you could review them (here
received a box of tires from Bontrager yesterday. I now have the Tubeless Ready versions of the XR, ACX, Revolt Super X and Mud X with four bottles of Super Juice. Plus the standard Big Earl 2.5, and 29er XR and ACX.
I will have the specs posted to my site in a few days after the tires have been stretched.
The Tubeless Ready (TR) tires have a different bead shape than standard tires (I will post pics). I believe they are to UST spec (am checking with Bonty) and are VERY
tight. I could not even come close to getting the tires on a few on my rims. Blistered my thumbs trying. The Mud X TR was not nearly as tight.
Bonty's TR instructions say to mount the tires on standard rims with inner tubes, inflate to 60psi and let sit (at least) overnight to stretch the beads.
Luckily I have several rims with deep center drops to mount the new tires on.
I will be riding the TRs soon, mounted on 819 rims with sealant and on standard rims with inner tubes.
Interesting that the 4 different TR models are made in three different countries (Japan [Super X], Thailand [ACX & XR] and Taiwan [Mud X]).
I think the concept (Bonty Tubeless Ready and Geax TNT) is sound. A light, mostly airtight casing designed
to be used with a specific
sealant. Beads designed
to be used with tubeless rims
. A system designed to work together from the start. TR and TNT tires are meant to be used with sealant only on tubeless rims and with inner tubes on standard rims or tubeless rims.
Thanks for sending the email!
