TPU Tubes

I've used they them work great. For winter used only on snow you should not have a problem. Follow the instructions for install so they don't twist.

I switched to Revoloop and have used them with great success. Much lighter than traditional fat bike tubes and more easy to carry a spare on the bike. I've never punctured one due to running over something however I have gotten a hole in one after letting some junk in the tire and inflating it before removing. Revoloop does sell a patch kit that is very expensive however I use the cheap Park Tool patches and they work very good. The Revoloop tubes are my go to for ultra distance races in the winter. A few things to be aware of: 1.) be carefull installing them - don't want them twisted when inflating 2.) I've never gotten a hole when riding them but have with rough handling outside the tire so be careful. 3.) They are much lighter than regular tubes - huge weight savings, and 4.) the main disadvantage if you do get a very small hole is that the hole is harder to locate to put a patch on - I've had to inflate the tube and hold it under water to find the leak.

I do keep considering going with the Rev toobs but have a curiosity of how supple they are for low pressure riding. Since I do a large percentage of my fatbike riding with soft tires for the flotation that riding on near full tread width can offer, I really would like to be able to continue that.

RockyJo, you have some snow time with em, whaddya say?

What I don't care for is the mess and cleanup of sealants, so tubeless is kinda ok but a cleaner method to that would be awesome.

On the pinhole front... Been there with SL tubes where I had to immerse the tube to find the leak. Not the end of the world since I keep a reasonable supply of tubes, new and patched. SL's tend to keep the softness/suppleness a priority.

I’ve run the tires as low as 2 psi for very soft snow riding. No issues with the low psi. Typically I run 3 Psi in the front and 4-6psi in the back depending on conditions. I like tubeless in all my other bikes but at these low pressures I can’t keeps the beads from separating thus the need for tubes.

What rim are you using? I have one pair of wheels setup for fat tubeless and run stupid low pressure in sand without too much drama, however, I would like to find a tube that can withstand being run similarly. Sand and snow are a thing and I like being able to ride in less than favorable loose sand with wrinkly, spongy tire for the irreplaceable flotation only a fatbike can deliver. Other pair of wheels are Surly Toobs.

I run a set of Sunringle Mulefut 26” rims and a set of 26” HED rims. Both with Revoloop tubes.

On the snow they are the way to go. My winter wheels are 94 mm ones that are not tubeless or low air friendly. Maybe 5 psi is the lowest I dare go. I ordered mine from Germany but now you can get them in Canada eh. I also had a tube cut on a sand ride by sand in the rim lots of sand. Make sure your rims are taped/ sealed well.

Fortunately, I have Clownshoe and Rolling Darryl for rims that I can run nearly flat tires with and drama free. Just wanna be able to keep it cleanly and such. Thankya, RockyJo!!
