Stans NoTubes Alpha 340 Wheels



An easy route into road tubeless. The rim profile makes set-up a doddle, and the fact they come ready to go is a nice touch.

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Stan's NoTubes Alpha 340 Team 3.30R wheels are light, fast and strong, and allow easy tubeless setup if you want to ditch your inner tubes.

Tubeless technology is prevalent in the automotive industry and over the last ten years has become commonplace on mountain bikes. So far there has been very little adoption among road cyclists, but with increasingly more choice of wheels and tyres from the big manufacturers, that's slowly starting to change and road tubeless is seeping into the public consciousness.

Stan's NoTubes is a name familiar to any mountain biker. The US company has made tubeless technology its USP, with special rim strips, valves and tubeless sealant able to convert most wheels into a no-tubes setup. The company has also developed its own rim, with a special internal rim shape, that it sells in a range of mountain, cyclo-cross and road wheels.

These Alpha 340 Team 3.30R wheels, with their 1,445g weight and £580 price, are very competitive. For comparison purposes, they are about the same weight as Shimano's Dura-Ace 9000 C24 tubeless-ready wheels and lighter than Fulcrum's Racing 1 2-Way Fit wheels, but cheaper than both.

The wheels use Stan's unique rim profile, which incorporates its Bead Socket Technology. This is essentially a sidewall that is 2-4mm lower than a regular rim, and which secures the tyre bead firmly into place. Once it's locked in there it's not budging. I've had no problems at all inflating tubeless tyres with a hand or track pump onto these rims, and once the tyres are up they stay inflated.

The rim is 22.6mm deep with a 20mm external width and 17mm internal. They're laced to DT Supercomp Black spokes (24 radial front, 28 2-cross rear) to a pair of 3.30R hubs, with DT Silver Alloy nipples. They're diddy little hubs and nestled away inside are stainless steel cartridge bearings, which have dealt well with heavy and sustained rain and taken a pasting riding over mud and shit covered roads the past couple of months. The machined braking surface has offered decent braking and shows no sign of wear. The freehub is 11-speed compatible.

Going tubeless couldn't be easier

The rims are pre-fitted with 2-layers of Stan's yellow rim tape and a 44mm tubeless valve. Fit a pair of tyres and some sealant and away you go. It really is that easy. The wheels can be run with inner tubes if you prefer, that simply requires removing the valves.

One of the best selling points of tubeless is reduced punctures. Removing the inner tube obviously eliminates the risk of pinch flats - when the inner tube is sandwiched between the tyre and rim. You have to hit a pothole pretty hard to do that, but it's not impossible.

The most frequent punctures are those caused by glass, sharp stones, flint and thorns puncturing the tyre and popping the tube. They're more frequent at this time of year, with generally more crap on the roads, but also rain acts as an annoyingly good lubricant for sharp objects to slice into tyres.

Remove the inner tube then, and replace with a liquid latex solution that solidifies upon contact with oxygen, and you have the recipe for less time spent repairing flats. Who doesn't find that appealing?

I tested the wheels with a pair of Schwalbe Ultremo ZX tyres (you can read the review here /content/review/95313-schwalbe-ultremo-zx-tubeless-tyres). Installation couldn't have been easier, with the required solution poured into the tyre, they inflated first time and have remained trouble-free for the couple of months I've been riding the wheels and tyres so far. The tyres are secure on the rims, with no hint of the tyre bead trying to shift in the rim.

Ride: Quick and strong

The wheels offer a sprightly ride, as you would expect from their low overall weight. They zip up to speed quickly, with a good response during out of the saddle sprints. They're reasonably stiff: push the wheels hard in a flat-out sprint or through a high-speed corner, and there's no detectable lateral flex.

They're also comfortable, the alloy rim and double butted spokes a good advert for classic box-section clincher wheels such as these. There's enough spring in them that rough roads are handled with good composure, making them an ideal year-round well, but especially good as we head into winter.

They're strong wheels, with impressive durability. I've been hammering them purposely through holes and cracks in the broken Tarmac on my local roads, and they simply shrugged it all off. I've not even needed to take a spoke key to the nipples yet. The bearings are still lovely and smooth after a couple of months.

They can take the punishment. That makes them ideal wheels for anyone who hammers their bike over rough roads, whether in sportives or racing. Their weight and stiffness makes them ideal on a lightweight racing bike, though they might not have the outright stiffness of carbon wheels for crit races, but longer road races should see them shining. For long distance touring or sportives they're well suited, with the added peace of mind that the tubeless setup provides. And they're light enough to put carbon wheels three times their price to shame when it comes to climbing.

I've been really impressed with these wheels. The simple tubeless setup, their weight and decent price and staggering good strength and durability. They come with a rider weight limit of 230lb (16 stone/105kg) though.


The Stan's rims have provided an easy route into road tubeless, with none of the complications often cited by tubeless detractors. The rim profile makes setting up tubeless tyres a doddle, and the fact they come ready to go is a nice touch.
