Found them far easier to fit than my old butyl inner tubes. Feel faster and definitely comfortable at the right pressure.
Great product with easy checkout and quicker postage no problems at all!👍👍
After about a months worth of rides and a thousand or more miles no punctures thus far. The spin up of the wheels seem to be a little faster as well.
I purchased the tubes, from this store for an upcoming race I had which I just completed this past Sunday, May 18, 2025. They shipped quickly and worked great. I’m sure I’ll order more in the future.
I have them in both road bikes and the weight reduction is pretty stunning - over 100gm per wheel saved in rotating weight. Feels good, and holds air pretty well too.
Have not ridden bike with the new tubes yet but the quality and weight seem superior to other tubes. Installed in 4.6 wide winter studded tires. Stated range for tube was 4.0 to 4.5 but seemed to work just fine. Highly recommend.
Based on my scale I lightened my Fat Bike rotational weight by 3/4 of a pound. Can really feel the difference accelerating with my Salsa Beargrease. About 30 miles on them and no loss of air. Alot cleaner than tubeless gel, probably lighter.
I depend on these tubes for my road bike. They've been 100% reliable and live up to their reputation as the lightest tube without compromising any strength.
Ok, trialing the change from Buytle tubes to TPU tubes I found my initial time with the problematic with poor air retention, regular punctures , punch punctures and difficulty fitting. This was with other brands that prioritized lightweight over other benefits. I found the TPU tubes from these guys a much better balance for every day riders with a weight half way between the super light and regular buytle tubes at just 46 grams each they roll better, improve puncture protection and maintain air as well as the Buytle tubes. A little pricey but I think worth the cost. Definitely space saving in the saddle bag and slightly larger in diameter so they sit inside the tyre when installing them reducing the chance of pinching them when installing them.
Bought as a backup for wilderness fat bike rides. Fits great in the bag. Had issues with shipping but contacted the company and they fixed it right away.
My purchase experience was professional and informative, when I reached out for help I was treated with respect and patience because of my lack of knowledge on the item I was ordering. I was treated with respect.
These tubes work great. You can actually feel the difference in weight. So far so good and I even order .ore for my other bikes.
P.S. Peter from Wheelscience was great to work with. He reached out to see if I had questions about rhe tubes I purchased. Thaks for your help!
Would always use tpubiketubes because of the great service provided and quick efficient response to any queries or issues.
Thank you
Fast delivery. Just raced 80k time trial in 32 degree heat with these tubes with no issues. They’re so compact I easily carried 3 spares in my pockets. I like the no frills packaging too - it means you’re not wasting money on fancy stuff.
Really like the tubes. They are so much smaller than standard tubes that I can easily carry two where one barely fit. They are much lighter. I have yet to flat one, so that is good.
Good option for lite weight spare to carry on my fat bike rides
I ordered the 26 x 3-4.5 inch TPU tubes for my Surly Bud/Lou tires on my 2014 Moonlander. Peter told me that they should work for inner width of 4.6 inches, which should be the case with 4.8 inch outside width Bud/Lou. All good. Holding air very well. Weight savings are substantial. Thanks for the great communication before I purchased. Yes, they are fine with 4.8 inch wide tires.
The 5 star rating is for the purchase experience. I run tubeless on my fatty and this TPU tube saves a ton of weight over carrying a spare fat tube, or even a 29er tube which is what I carried. I'm confident it will work great should I ever need it. I'll probably buy another just so I can try it!
