TPU Tubes for big road tires

[alexgaignard]

I'm fed up with tubeless on road tires never working so I want to simplify my life by going to TPU but I'm struggling to find one that would fit my needs.

I want an 80mm aluminium valve and for it to work with 35mm tires.

So far the only option I found that is close is this https://fr.aliexpress.com/item/1005012286181375.html 80mm stem, fits 33 to 45 tires. BUT the valve is plastic.

All the alu valve I seem to find are max 65mm, or some are 80 but only fits max 32 tires.

Have any of you found anything ?

I've been using cyclami tpu tubes which have a plastic valve on my 47mm (50mm WAM) commuter tyres for about 1 year and haven't had a puncture or leak.

I’m using the purple gustavo tubes 35-50mm on my gravel bike with 40mm tires. Plastic valves, but no issues at all. Super cheap too, usually get them for about $6 for 2 with the bundle deals.
