Vittoria continues their mission to carry readability to bicycle tire tech, now with a White Paper explaining the professionals & cons of the three most important sorts of internal tubes – Butyl, Latex & TPU. Positive tubeless has come to dominate a lot of contemporary street, gravel & mountain bike tires, however the majority of bicycles out on the planet nonetheless have internal tubes of their tires. And with street Grand Excursions and even Spring Classics being raced and received on clinchers, tube tech continues to be value a deeper dive…
S0, how do you select?
Vittoria: Bike Inside Tube Varieties Defined
c. Vittoria
That is the second within the Vittoria White Papers explainer collection – following up January’s “Bicycle Tyre Varieties and Methods“. And the concept is identical… attempt to clear up some frequent confusion round various kinds of on-road tire and off-road tire setups with a purpose to give cyclists sufficient info to make extra knowledgeable buying selections based mostly on what’s going to be finest for them and their kind of driving.
So, for everybody on the market driving with internal tubes of their clincher tires, or simply seeking to carry a spare tube when a roadside tubeless restore received’t work, this primer ought to assist decide the most effective tube for you…
Just about each fashionable bike has pneumatic tires, and whereas many have gone tubeless, most nonetheless have internal tubes inside. Tubes are simply easier and cleaner to put in, don’t require a lot technical ability, and work fairly effectively throughout a variety of motorcycle driving types. Plus, they’re straightforward to interchange and even patch normally in the event you get a flat, are small & gentle sufficient that it’s straightforward to hold a spare, and they’re usually a low-cost merchandise to interchange.
The three fundamental sorts in use are artificial butyl rubber (traditional black), extra premium pure latex rubber (in a variety of gentle & pastel colours), and the costliest thermoplastic polyurethane, i.e. TPU (in a number of translucent, or usually vibrant colours).
Vittoria’s White Paper goes fairly deep into the internal tube, its historical past on bikes, and why you would possibly select tubes vs. tubeless.
In-house Testing Comparisons
However in addition they consider the important thing efficiency variations between every tube kind, and did a little bit of in-house testing to counsel how they examine. Unsurprisingly based mostly on every part we’ve learn in recent times, the heavier normal butyl tube has the best rolling resistance of the three, and is a little more prone to pinch flats & punctures. It’s even probably the most proof against warmth build-up, and has the longest lifespan inside your tire, almost certainly.
Latex comes within the center when it comes to weight and puncture resistance, however is simply nearly as good as TPU for decreasing rolling resistance.
That leaves TPU – the most recent technological advance in bicycle internal tubes – because the quickest rolling, probably the most sturdy, and the lightest weight. It additionally seems to be extra sustainable because it requires much less uncooked materials and is quickly recyclable.
So what’s the draw back of TPU then?
Value in fact. Vittoria’s personal butyl tubes begin at $8, latex at $16, and TPU tubes at $35. Every newer materials is 2x as costly as these beneath it, an enormous step up in price to get comparatively small beneficial properties. Then once more, upgrading a pair of TPU tubes is a comparatively low-cost approach to enhance the efficiency of your bike within the grand scheme of issues.
Free watts aren’t actually free. However for $70 this might get you decrease rotational weight, decrease rolling resistance, and improved sturdiness in case you are changing the inventory butyl tubes already in your bike. And people outdated tubes can nonetheless be a practical spare in the event you do flat the flowery TPU tube sooner or later.
After all, Vittoria’s White Paper perspective skews in direction of their very own merchandise, however the identical assumptions might be made for almost some other tube producer.
And Vittoria did simply launch their new Extremely Mild Velocity TPU tubes this summer time. But there are loads extra TPU internal tube choices from Tubolito, Schwalbe, Pirelli, RevoLoop & a number of extra… and so they are available various sizes and thicknesses to go well with every part from street to gravel to cyclocross to MTB to metropolis commuter bikes.
