VeloTubes Fat Bike Inner Tubes 26 x 4.0 Threaded 33mm Schrader (Auto) Valve, Fat Bicycle Tubes, Pack of 2 or 4

In the land of cheaply made bike tubes this looks to a possible winner. Most of my fat tire tube failures have been at the base of the valve stem. I run Tannus Armor tire inserts and they work great. I've had several recent failures of the bike tube I purchased elsewhere and from another manufacturer. These seem to be well made with a full length metal valve stem. It also comes with a nut to keep the stem in place in the rim. Only time will tell if these live up to initial expectations. It comes in a two pack so for under 30, I'm expecting them to be of above average quality.

I started buying Velo tubes 2 years ago for a fat bike because the price was low and it had metal valve stems similar to Presta valves. This is dutable plus is handy on a fat bike with Schrader valves because you can place a valve nut on the stem which prevents the stem from sinking into the tire while doing a roadside repair. This is pretty common on a big tire and this is a big selling point.since trying these on my fat tire bike, I was impressed by the quality of these tubes for the low cost and have been using these tubes on nearly all of my bikes now.

I recently purchased 2 fat tire ebikes, one will be for off- road use. I wanted these on hand as I've read that the original tube/ tires are easily pierced by thorns. I'll update this review when I get to use them.

Outstanding valve stems with threaded washers. It makes keeping the valve stem straight up and down easy when replacing tires or existing tubes.

Perfect fit. Half the price of OEM Kendra/Rad. The threaded metal valve stem/nut combination really aided installation. Many "brands" appear to be the same tube, comparing weight and thickness specifications is difficult. Quality seems "maybe" a little thicker than OEM, by my observation and similar online tube reviews.

Extra parts

We've been having an issue getting the bead of the new tires to sit properly, which has lead to the tube blowing off the rim a number of times. The tube hasnt broken despite falling entirely off the rim while I was riding and being dragged back to my starting point.

I've gone through three of these tubes in a matter of months on my 26" wheel e-bike. Granted, the bike is heavy, but it seems like the quality of these tubes is not very durable. I was hoping the quality would be better due to the brand name, but that doesn't seem to be the case.

Got these almost a full week earlier than estimated. Tubes feel very heavy duty and well made, I love the threaded valve to hold in place and protect from damage.Both installed,pumped to 28psi and holding perfectly. Will try to remember to update on longevity in 6 months or so. I'm hoping my regularly scheduled FLAT tire issues will be permanently ceased;-)EDIT:! BEEN ALMOST 6 MONTHS NOT A SINGLE FLAT. , ALMOST 2000 KLMS RIDDEN ON MY EBIKE ! WORTH THERE WEIGHT IN GOLDEDIT* SO..... immediately after my last edit I left for a ride, 1.4 KLMS into it I got a flat ffs . I jinxed myself! But the review was worth it and still stands 😉

parfait

I have been riding my bike for 2 weeks now, and there is no sign of leaks so far.
