Have any of you ever had a problem with the thickness of the valve? Unfortunately, the valve does not fit with me in the rims (45mm carbon clincher). I do not know now whether I should try to remove material at the valve or to enlarge the rim hole.

I received my tubes and the "patch kit" - although the patch kit includes rubber cement...... I doubt that works for these tubes as every other legit manufacturer uses self-adhesive patches. Anyone else with input on this?

Also, I put mine straight in the saddlebag without testing 'em.

Have any of you had faulty tubes out of the box?

Hi folks, got a set of the tube. Can folks advise, what is the use of the O-ring on the valve stem? is it supposed to be at the bottom of the stem? or ?

You don't need it, it's meant to be like the small nut you'd get with a butyl or latex inner tube that you'd screw onto the stem once it's on the rim

I see... that can be useful to start pumping air into the tube. So, reckon the O-ring is supposed to be on top of the rim exposed.

A mechanic told me the O ring (at least for Tubolitos) should be on the inside of the rim ¯\_(ツ)_/¯

I put it inside to protect the cutting from rim.

TPU easily deforms. When inflated with O-ring inside it will make a crease on that area.

Has one recently been able to buy the Ridenow gravel tube (700 x 32-47C)? Seems to be out of stock everywhere I check

If it is a solvent specifically made for gluing difficult plastics (and not just the usual vulcanizing agent used for butyl or latex, which is hardly more than petrol with some additive to make it evaporate not quite as fast), then it might very well be the good stuff. Tubolito has gone through multiple iterations of self-adhesive patches before eventually switching their repair kits to Rema Tiptop Camplast which seems to be the least bad so far.

It is literally regular general rubber cement found in any decent bike shop... Says on the tube too, "for all kinds of rubber".

I learned there is both vulcanizing something and then rubber cement, both intended for the same stuff basically, same material.

There is just no way this rubber cement is gonna work with TPU plastics. I have some Revoloop patches but I never got to use to them yet, which is great :D

I carry 2 Ridenow tubes with me on all road rides, really great! Saving so much space and weight in the backpocket.
