This is going to be a little different... I saw a video on youtube with Caden from Caden wheels explaining how he used sealant in TPU tubes with tubeless tires. Not TPU specific sealant, just tubeless sealant. He claimed the sealant lasted longer because there wasn't as much evaporation from inside the TPU tube and that the chances of a burp flat went dramatically down.
I decided to try it and here's the result so far. TPU tubes in this tire with sealant have been flat free through the Tour de Tucson and several hundred miles more. These tires roll and corner great and have been reliable. I won't know if I've gotten any punctures until I get one that's so big the sealant won't fill it or I take the tire off to replace it, but so far Caden has been right.
Review for the 38mm Schwalbe Pro One TLE tire. I installed a 38mm Pro One TLE to replace a worn 34mm Pro One TLE on my Specialized Turbo Creo e-bike that I use for work commuting, which is a 48 mile round trip commute. The extra 4mm width added some comfort/cush to the stiff riding frame. Commuted 1500 miles on this (rear) tire with no issues. Held air just fine and no flats in over 1600 miles commuting. Some conditions include sticks/twigs/debris on a canopy covered trail. Tire is starting to square off but after 1600 miles w/ average speed at 21.3mph with the power of an e-bike, I'd say this tire handled it just fine.
Great performance overall, fast, responsive, grip wet & dry is phenomenal, but I've experienced flats every time that I ride on them, and the TPU tubes are expensive.. These tires are definitely game changers and their performance is everything that Conti says, but their reliability/durability is very costly. Not sure I'd want to chance racing on these. In a amateur Crit, RR or TT if you flat you're pretty much done. Would hate to drive hours, spend money (hotel, food, entry fees) and countless training hours, only to flat in a race!! Although flats/punctures can happen with any tire, these tires seem more susceptible than others. If you want the ultimate performance get these tires, just remember to keep extra tubes or plenty of sealant on hand.
I love these things. I use/have Dyna plug kits in my motorcycles - i've used them with good success. To be honest, i haven't used them on a bicycle yet. (How's that for insurance?)
i bought my first one when I rode sweep for the Boise Gravel Gala. (My daughter helps organize it.) I needed a good tire repair kit incase riders had flats. Didn't need it - back to that insurance deal.
I finally bought a mountain bike and a gravel bike, so i bought one for each. This way, should i have a flat, I'll be ready. Knock on wood - no flats yet.
This isn't cheap, but it's well packaged, and looks cool as heck.
All three of mine have been purple. So pretty! I
