2 Pack RideNow TPU Inner Tubes 700C x 18-32C / 32-47C with 45mm/65mm/85mm Metal Presta Valve, Removable Valve Cores for All Road or Gravel Bike (Include Bike Tube Patch Repair Kit)

Well these are beautiful Barbie pink tubes and they work! The valves are easily removed so you can add an extension if you’re running deep profile rims. The package says they’ll work with rim or disc brakes, I’ve used them on my rim brake bike with no over heating problems. I’ve only got a few hundred miles on these but so far so good.

I switched from butyl tubes to TPU innertubes because i hate the way butyl leaks, punctures easily, is heavy & bulky. I also did not want the mess & work of tubeless so TPU seemed like the perfect solution.I’m using these exact tpu inner tubes with Pirelli P Zero Race 700x26c tires, on Elite Wheels SLT 50mm carbon aero wheels. They ride absolutely awesome, hold air exceptionally well, & in my experience are very puncture resistant. The new improved valve stems are high quality as is the tube itself. I am super impressed with them & have since bought more as spares for my saddle bag & for my training bike in addition to the ones on my fast bike. Have lots of miles on these tires & tubes & would absolutely recommend.

This was my first foray into using TPU inner tubes after hearing recommendations from other cyclists. The brand name TPU tubes are pricey (e.g., $30 or more per tube) so I ordered these "RideNow" tubes since they got some decent reviews on Amazon and only cost about $16 per tube. Also because they have metal valves. However, I learned the hard way that only the top section is actually metal; the bottom portion is plastic and prone to breaking. As a result the first pair of RideNow tubes I tried both failed very quickly due to user error on my part. After figuring things I ordered a 2nd pair and haven't had any issues since. The tubes an attractively packaged and really do have a noticeably nicer ride quality vs. butyl tubes, but they could really use some better & more complete instructions. The leaflet that comes with the tubes has an extremely small font (you may need a magnifying glass to read them), and aren't very thorough. I also tried going to their instructions on the Web but they weren't much better. So I would recommend these tubes but have a few tips: 1) be gentle with the valve stems and be sure to use the protective plastic spacer that covers the base; 2) also don't tighten the retainer nut (w/O-ring) too tight; and, 3) try to avoid using CO2 with these tubes (which I understand is generally true for most brands of TPU tubes).

Was a bit skeptical of these and didn't know how they would perform. Longevity test still in progress, but they accepted sealant with no issues (which is the reason for purchasing TPU with the removable core). The locknut system on these is much better than the other versions I purchased. The pink is fun for some of my bikes, but I wish they came in a standard black too. Pink doesn't go with every look.

Garbage. One of the two was defective out of the box, leaking from the black material at the base of the stem.

Light weight and easily repair flats. Are extremely small and take little space in my bag.Quality is good. Have purchased many times without defects.

Just received these after looking at a few different brands. I've read all the reviews, pros, cons,and complaints but figured at $25 I'd give them a try. I've run tubeless for years with zero problems. I think I've had a single puncture that I didn't even know about until I got home from my ride. However, over the past few years, I've grown a bit weary of having to clean out old, dried up sealant and adding new sealant. Only did this every 6 months but it's a mess and a bit of a pain. Anyone who has ever installed a tubeless tire on a rim knows the struggle.Enter the RideNow TPU tubes. I've always carried a spare tube or two with me on rides just in case, but honestly, they take up too much space. I can carry two or three of these in the same space as one butyl tube. I ordered 2 of these TPU tubes and installed one, paying close attention to the instructions. Of course I did this after the ritual cleaning of the sealant. I will say that if these work, I will not miss that part. The hardest part of the install is fitting the tube on the rim. Just as the tire is very tough to get on the rim, so too is the tube. It took some doing and some patience, but I did manage it. After about 30 minutes of fiddling, I got both the tube and tire back on the rim. I inflated with no trouble to 5.4 bar/78 psi, the recommended amount for my weight and well under the limit for the tire. Interesting how even with tubes, I still get the familiar pop of the bead of my tubeless tires seating on the rim during inflation. I'm going to leave the rear tubeless for the time being to compare the air retention of the two. Tubeless usually needs topping off every other day or two. It will be interesting to see how the TPU tubes stack up.I ordered 2 of the tubes with plastic valves initially but decided to keep them and ordered these with metal valves. I installed the plastic valve tubes on my aluminum rims and the metal valve tubes on my carbon rims. For now just one of each to compare. The spares are in my saddle bag. I only had room for one butyl tube but 2 of the TPU tubes fit with everything else in there.The plastic valve tube has been installed for just over 24 hours with no noticeable loss of air pressure. I should note that installation on my aluminum rims was much easier since they are not tubeless rims. I'll check on the metal valve tomorrow. So far I have no complaints. Time will tell how durable these are. I've yet to do any rides on them yet so I cannot comment on the ride quality versus tubeless.Short 10 mile ride today. Front wheel has tpu tube while rear wheel is still tubeless. No issues whatsoever. Hard to tell the difference in ride quality.

I made the switch from butyl tubes to TPU tubes. I have ridden for over 30 years and ride about 6 - 7000 miles per year. I will never go back to using standard butyl tubes. There are many claims about why TPU tubes are better, they are lighter and offer lower rolling resistance but mostly the amount of space it takes to carry extra tubes. I do a lot of long distance riding and always carry two extra tubes, the amount of space these tubes save is amazing. It is easier to patch TPU tubes and they do not leak down the way butyl tubes do. I have been using them for a year and have not had a flat, oh course now I have jinxed myself by saying that out loud. The quality of these tubes is great. I would not pay $30 per tube for the other brands.
