I punctured a Schwalbe Pro One tubeless tyre on a tame section of gravel last weekend and it got me thinking about Road Tubeless.
I’ve got a long and storied history with Road Tubeless dating back to the very first Road Tubeless tyres the 23mm Hutchinson Fusion 3 from around 2009. I’ve tried a handful of tyres over the years however I’ve always reverted back to my favorite non-tubeless tyre the Continental GP4000s as I found no decrease in the number of punctures, a worse ride quality, a more sluggish feel, and worse wet-weather grip with tubeless.
The 28mm Schwalbe Pro Ones that I’ve had on a pair of Maker SLD wheels for the past few months were the first Road Tubeless tyre that I’ve liked. They feel half decent to ride, they’re reasonably supple, their wet weather performance is pretty good, and they feel pretty quick. I was disappointed and surprised when a small sidewall nick wouldn’t seal and made me DNF a race.
So where is Road Tubeless at?
Both tubeless…but very different definitions of “fast”
The current crop of 30-40mm tubeless tyres for gravel bikes is amazing. For gravel bikes and mountain bikes I think tubeless is a no-brainer so everything discussed here is for pavement-based bikes.
Personally I think 28mm is the tipping point for tubeless. Anything narrower and you won’t get any advantages from going tubeless, and anything wider and you’re almost guaranteed to get the benefits of a more supple ride and fewer punctures. 28mm seems to have all the pros AND all of the cons.
28mm tyres are a squeeze on most rim-brake frames and brakes so for rim brakes we’re optimising rims around 25mm – 28mm tyres. Most modern disc brake frames will take wider tyres so our disc brake rims are optimised around 28mm tyres while keeping the ability to run 25mm without any problems. All of our carbon rims are tubeless-ready but can also be used with regular tyres and tubes.
Sealant makes a different. Stan’s is the industry standard and generally has the best results in lab tests but Finish Line have a new sealant which doesn’t dry out and looks really promising.
Tubeless tyres are still harder to get on and off rims than regular tyres. Rim design has a part to play in this as generally rims are made a touch larger to be on the safe side. Tyres have a much bigger part to play because they’re made much smaller in diameter to avoid the risk of a blow-off, and their size varies a lot from tyre to tyre due to the production methods used. The combo of large rim and small tyre means cursing and swearing especially when everything is covered in sealant. I’ll talk more about this in another newsletter and explain why our carbon Maker range of rims are designed the way they are (hint: we’ve got one of the lowest possible outside diameters to improve ease of fitting tyres.)
Continental have just released a tubeless GP5000s tyre and I can’t wait to get my hands on a pair. Continental are definitely slow react to the tubeless trend but based on how amazing their GP4000s non-tubeless tyre is I think the entire bike world has high expectations for the GP5000s. They’re due shortly-ish.
As always thanks for reading and I value your feedback! I’ve got two questions which I’d love you to answer either directly or on our Facebook / Instagram:
What is your tubeless experience? What tyres and sealant are working for you?
