Best TPU tube brand

[edy]

I believe I ordered them from several brands from AliX, used them on different brake setups (rim brakes, disc brakes), different tires and widths (25 - 32), not a single issue.

In my experience, the problem with 99% of TPU inner tube is the valve, ever!

Too much leaking, no matter the brand.

I agree. Recently experienced leakages with ThinkRider and Cyclami TPU tubes.
They have a similar valve core design, I noticed that the valve could be threaded in further - which seems to improve the leakage.
Anyone else noticed the same with ThinkRider and Cyclami?

I've been using old Cyclami TPU tubes with the entirely threaded, metal valves. They're about 2 to 2.5 years old and about 2,500 km (I don't ride as much as I should)

I have a stash of RideNow tubes as backup but haven't ever had to replace the originals.

Anyone know of there's a shelf life of these?? I doubt it (hopefully).
