TPU Inner Tubes

There are a few recent threads on this one - a few of us have them on at least one of our bikes, and to the best of my knowledge have had no issues.

Admittedly mine are the expensive Pirelli ones, as they were for my best bike, and it was before I was aware of Ridenow tubes on Aliexpress I think it is - they worked out at the time when I ordered a batch, at about £4 each only, so exactly the same cost as a butyl tube.

Instead of me keeping prattling on on here, let me see if I can find the thread for you.

*You'll have to excuse the ramblings of a forum member on there who doesn't read any of the replies properly.

Here we go, took a bit of finding!

*I was evidently paging through the forum whilst you posted @super_davo 🤪

Don't forget the chaps inability to manage basic maths as well.

This has reminded me actually, I do need to place an order for some more, and of different widths.

This reminded me to actually order some, I have been meaning to since the last thread!

@davidof if you have a mooch around aliexpress there are various welcome deals for first time buyers. I have just ordered a 4 pack of 700c tubes and a 4 x 29er mtb tubes. Total cost was £36, so about £4.50 per tube which isn't too bad.

It does look as though the standard price has jumped up a bit though in the last year.

I am using some Tubolito ones on the road bike, handy as they pack small (fairly easy to patch) I bought a couple of Ridenow ones as spares, they are very thin and I managed to wreck one putting in the tyre. Personally wouldn't bother with the Ride now ones again.

What did you patch it with. There was something on BR about patching them with insulation tape, I tried it on the one I punctured and it stayed inflated but I wasn’t sure about using it again.

That was me. Said tyre has now done hundreds of miles and is performing as new. 😎

I wouldn't inflate the tube outside of a tyre though.

Yeah, I read somewhere that they will deform if inflated outside of a tyre.

I started using RideNow tubes (36g) about 8 weeks ago. The one at the front has held up fine, but the one at the back started losing pressure fairly quickly so that after 3 days, when the front had dropped from 6 to 5 bar, the rear had dropped from 6 to 1 bar. This was after it had been on the bike for about 4 weeks and included a cyling holiday in Gran Canaria which has some pretty poor road surfaces. I did a biggish ride and although the pressure felt good when we left the cafe I lost all pressure about half and hour later. When I examined the tube at home it had pinch punctured, which I expect happened when I noticed that I had a flat as I hadn't hit anything before that. I had managed to lose the only repair kit that I had bought so I couldn't fix the pinch puncture and find out what else was going on to cause the initial loss of pressure.

The replacement also pinch punctured on a rough patch on the corner of the road where I live when I was returning from a club ride. That was a bit of a surprise, the road is not that bad and I ride over it several times a week so I wonder if this tube had also lost pressure.

I am a bit nervous of using the RideNow tubes, I bought 4 initially from a UK ebay source and I am on my last 2. I have ordered another 5 from AliExpress though so I haven't given up yet, maybe I've just been unlucky.

I've been using them on my carbon & alloy rims. I posted on another thread that I probably wouldn't trust using them somewhere like the Alps or GC where you're probably braking a lot more on long descents. I've used them for TTs/Hill Climbs and they're ideal. I've been using them for general riding and I notice that unless you have them at around 80-85psi they can feel a bit spongy/sticky.

I’ve been using them for a year (thousands of miles) without issue on alloy rim brakes. I did have one puncture that no tube would have withstood and it was easily fixed, at home I should add.

For clarity, I use the 36g version for reasons above. They are also much lighter than butyl.

The reminder worked and I ordered some this week 👍

Don't hold me to it, but yes, as far as I could see the ride now are all the same tubes, just the weight difference as you say. I just picked the offer that looked to be best value having done a few sums for each of them.
