The Maxxis Welter Weight 29er inner tube is a good middleweight, robust tube that’s good for hard-hitting 29er riders.

The torus-shaped Butyl rubber hoop has been in use for over a 100 years and, despite improvements to tubeless technology over the past few years (wider choice of tubeless tyres and rims) many people still prefer the simplicity of the humble inner tube. There’s no faffing with getting tyres to seal, no spilt tubeless sealant over the garden patio: just pop an inner tube in the tyre, inflate and ride. Easy.

The Maxxis Welter Weight tubes are made from 0.9mm Butyl rubber to give a good balance of weight and puncture resistance. Maxxis market the inner tube at ‘aggressive riders’ and while lightweight isn’t high on the agenda, at 200g they’re a fair chunk lighter than a regular tube at 250g. But importantly they’re noticeably thicker than the cheap-and-nasty inner tubes that are very often fr toitted to brand new bikes. So you could save 100g on both wheels with a pair of these inner tubes. If you’re concerned about weight though, you’re probably tubeless already.

Assessing an inner tube isn’t the easiest task in the world. There are so many variables that can influence your risk of a puncture. A lot can come down to riding style, terrain, tyre pressure and, sometimes, pure luck. No inner tube (except a downhill tube) is immune to pinch flats and thorns, but the Welter Weight’s have impressed.

I’ve been using the Welter Weight tubes, paired with Schwalbe Hans Dampf tyres, for a good couple of months now, and I’ve not had a puncture in that time. If you need some good quality inner tubes for your 29er, these are worth consideration.

Verdict

As good as inner tubes get.

Pros

High quality

No punctures…so far

Cons

A bit pricey
