VeloTubes Premium Fat Bike Tube - 26 X 4.0 Presta (French) Valve Removable Core - 2 OR 4 Pack!

Good tubes at a good price. They are a bit thicker and heavier than I expected (& compared to the tubes being replaced) which can be a positive for flat protection.

I found the tube to be a great replacement for my Specialized FatBoy 4.6'' tires. These tubes are definitely heavier than the OEM Specialized tubes that the bike came with (I did not weigh them -- the difference is apparent in your hand) but this also seemed to translate into greater flat avoidance. 14 months later with nearly-exclusive off-road use and zero flats so far.

Very pleased with this product. The valve is threaded so it can be locked down and the valve is removable for adding slime or other sealants.

These seem to be holding up pretty well they are a little thin in but that helps make them lighter weight I put slime in them and I use a I use tube protectors or tire liner. Holding up well

Replaced tube in my Maxxis 26 X 4.6 Ground Control. No compatibility issues as yet after 50+ miles

Got some new fat tire rims and they required presets valves, so I picked these up. Mainly because they were reasonably priced. They are heavy, but hey, it’s for a fat bike. I don’t think anyone makes a light weight race tube for this size. Holds air and haven’t flatted so 2 thumbs up.

Great value for a fatbike tube, the only thing is you will need to change the presta valve inserts as they are junk, they do not seal properly and difficult to turn.

These are heavy duty tubes. looks like they should run some miles. I use a fat tire bike for downhill biking at a resort so they get lots of flex.

Pretty heavy, would not have bought if there were other options

Work great
