Atlas TPU Road & Gravel Inner Tube

A dependable TPU inner tube. Really.

The Atlas TPU Inner Tube is built for riders who want the weight savings of TPU without the fragility that usually comes with it. Seam-welded thermoplastic polyurethane gives you the durability of butyl at roughly one third of the weight, so you get faster acceleration, less rotational mass and a tube compact enough to live in your jersey pocket.

While most TPU tubes go ultra-thin to chase grams, ours use a 0.3mm wall — significantly thicker than the competition — for real-world puncture resistance you can actually trust. A robust aluminium valve with a removable core means you can run sealant, swap cores and service the tube exactly like a butyl one.
