Decent Road Tubes

[love2fly]

Hello

I've recently upgraded my Roadbike wheels and therefore tubes - can't remember what tubes I used to use but I'm finding my current (Kenda rear, Spez front) only hold pressure overnight - and not that well. I only used to pump my road tyres once a week or so and now it's like my MTB ie - night before a ride.

So I'm looking for tubes that keep pressure well (around 7 bar) and I need 80mm valves to fit Zipp 404's and pref removable cores....

Thanks in advance

I have been happy with the Pirelli butyl sport tubes, but they only come in a 48/60mm valve (Non RVC), the RoadTube has the RVC capability.

Next best I could find online is the below:

Thanks. I actually bought a Conti as a spare. Might try it and see if it's any better. I'm not surprised the Kenda is rubbish but I AM surprised that the Spez is crap.

Conti used to be my go to because often it was the only tube available with RVC.

I've heard of light weight tubes losing air but for the rest they are generally all the same.

All tubes puncture the same. Stock up on the cheaper options and watch where you are going.

Not found that specific tubes lose pressure. Tried pretty much every brand there is. As long as the tube specification match the tire. For example, don't use 23mm maximum with a 28mm tire, could pull away at the valve. Try any other brand, see if you have better luck.

It's not the puncture vulnerability but the pressure loss in 24 hours. Like I said, I only used to pump my previous ones once a week....

Should ideally check your pressure before every ride, or at least I do.

I mostly keep my Roadbike in the car for a week at a time (front wheel out)and check pressures randomly reaching behind me - after 20+ years you can do it by feel but with my current sieved tubes I have to take it out every evening and pump.

Try About 30 to 40 ml of sealant inside tubes.

Buy new Tubes from a Major bike Shop where stock turns around quickly.

actually no. I've found over the years that the cheaper brands tend to puncture much easier than the more established brands.

I've not had problems with Kenda at all, actually I think I may be running one in the rear at the moment and I only top that up maybe once a month.

Do you not perhaps have some small leaks ? because even the cheapest tubes tend to hold air for longer than 24 hours when not punctured.

sealant in tubes does not work...

just makes a mess.

the inside of a tube is different from the inside of a tyre - maybe it is that white powder?

the friction between the tire and tube makes it impossible to seal from inside

Trust me, I have tried it with many different variations.  

On a road tire the volume is small and pressure high  ... mtb vice versa bigger volume lower pressure
