AR-PRO Bicycle Tubes Race 28 700x20-25C 700x32-47C Bike Tube, 700C Inner Tube with Presta Valve Super Value Bundle (Pack of 6 Tubes & 2 tire Lever)

good quality

Great product. Good quality. I recommend it.

Nice to buy in bulk, but you do run the risk that there's a bad one what you only discover when you reach for a new one after several months sitting in the box. Not sure what kind of recourse we would have for that (and, yes, it has happened to me before with other tube purchases).

Very affordable inner tubes. A 6 pack of inner tubes for $40 is nice. Comes with tire levers which is an added bonus.

I like to have 2 spares, one for me, and one for others if needed. the durability is there and much better cost than the $8-$10 per tube at the bike shop.

Good

These tires are very hit or miss. This is the third box I've purchased, and it is the second one where at least 4 out of the 6 tubes popped at 100psi. There is no damage on the tire, the rims are freshly taped. Saving a few dollars is not worth the hassle.

5 stars.TLDR: tube withstood a lot of abnormal friction and heat and still didn’t pop or leak. Nice tubes.I Haven’t had these for long but was riding yesterday in the heat with the bead of my tire not seated properly. The tire was bulging out exposing the tube partially, which was rubbing against the brake. This was my fault for not double checking before heading out. constraint, I rode the bike like that for maybe a couple miles until the thing had swollen to the point I couldn’t go any further. I reset the bead today and was able to use the same tube and tire without any problem today. I’m impressed as when that’s happened before I’ve usually had to discard both the tire and tube. I actually had a blowout last time. Anyway, 5 stars to these tubes and continental GP 5k tires.
