Facebook Twitter LinkedIn Pinterest Bluesky Threads Need 50mm TPU tubes. I don't see anything out there. Any thoughts? I just have to switch to MTB tubes (29 x 1.9-2.5)?? (and no, I don't want to do tubeless) by Global-Panik Bicycling Biking Cycling Gravel Cycling Gravelcycling
linhromsp on September 18, 2025 9:20 pm If u running 50mm. Tubeless is the answer, way better than TPU. You can just send it down lolz

I swapped tires too often on my gravel bike
TheWitness37 on September 18, 2025 9:40 pm I switched my seigla to tubeless. I’d recommend that. And keep a plug kit on hand just in case. Much easier.
johansonnss on September 18, 2025 9:40 pm Theres plenty of mtb tpu tubes on aliexprs for little money
Antti5 on September 18, 2025 9:41 pm What’s the problem with going to “MTB tubes”? A tube is a tube, and a fat gravel tire is just a narrow 29″ MTB tire.
RCE_Andrew on September 18, 2025 9:49 pm Check Pirelli. I use TPU tubes on my 650b 45mm and I’m fairly sure they make them for 700c 50mm too.
db_peligro on September 18, 2025 10:38 pm 29×2 and 700×50 are the same size. Yes 29×2 tpu tubes will work fine for you.
rhinodakid on September 18, 2025 10:39 pm Just bought some of these. Very happy with them. https://www.tubolito.com/
joelav on September 18, 2025 11:42 pm RideNow and Cyclami make wide gravel TPU tubes. I’m tubeless but use these as emergency spares. They have 65mm valve stems too for my 50mm deep rims
chunt75 on September 19, 2025 12:01 am Highly recommend tubeless, especially if you’re using that Seigla on the terrain it’s designed for
sac_cyclist on September 19, 2025 12:13 am I bought TPU’s for my 700×40’s when they are replaced I’ll go tubeless

Tubeless is the answer.
