Specialized's long-awaited tubeless cotton tires are finally here, and they're a game-changer for cycling enthusiasts. After months of anticipation, the brand has unveiled its latest innovation, and it's a real treat for those seeking a unique riding experience.
The Turbo Cotton and Cotton tires have been a staple in Specialized's lineup for years, but the introduction of a tubeless-compatible version takes things to a whole new level. With a rich history dating back to Tony Martin's World Time Trial Championship win in 2012, these tires have evolved to meet the demands of modern cycling.
But here's where it gets controversial... we've actually spotted these tires in action way back in 2025 at the Critérium du Dauphiné, with logos discreetly covered up. So, it's been a long journey to get them officially launched.
For those new to the world of cycling, let's break it down. Specialized offers a range of tire options, and it can get a bit confusing. Here's a simplified guide to help you navigate their product range.
The original Turbo Cotton is still available in 24, 26, and 28mm sizes, featuring the iconic golden/yellow sidewalls. Specialized also introduced the HOTN - Hell of the North version, offering enhanced protection and tread, but it's no longer available on their website.
There's also the 'Turbo Cotton Folding Racing Only' tire, available in 26 and 28mm sizes. This 320TPI tire boasts the T2/T5 compounds and a cotton casing, but it's designed for use with tubes.
Last year, we noticed teams using the S-Works Turbo TLR tire at Opening Weekend. Easily recognizable by its unique sidewall color and hot patch logo, this model is tubeless-friendly and goes up to a 30mm size.
And this is the part most people miss... the demand for a tubeless tire with the characteristics of the cotton sidewalled model, but in a larger size, led to the development of the Cotton TLR. These tires feature a polyester core with a cotton wrap, which is believed to aid in containing tubeless sealant.
Specialized claims that 'the new tires deliver the feel of cotton with the speed and precision of modern tubeless technology.' An intriguing fact is that only six pairs of these tires originally existed, with Bora Hansgrohe allegedly refusing to give them back, prompting Specialized to produce more and go into full-scale production.
This story alone is fascinating, but what really caught my attention at Opening Weekend was the clear sealant applied to the Cotton tires used by Red Bull Bora. The team mechanic claimed it was for protection, but we're digging deeper to uncover more details.
The Cotton TLR tires will be available in 38, 30, and 32mm sizes, with weights quoted by Specialized as 280, 290, and 320 grams, respectively. Constructed with a 320 TPI (threads per inch) and utilizing the Specialized Gripton T2/T5 compound, these tires offer a seamless tubeless setup.
Specialized launched five new tires just under a year ago, including the S-Works Turbo TLR, which uses the same compound but with a 120 TPI casing. The brand emphasizes that these tires are manufactured to ISO standards, ensuring a high-quality product.
So, there you have it - a comprehensive look at Specialized's latest tubeless cotton tires. But here's the real question: do you think these tires will revolutionize the cycling world, or are they just a clever marketing move? I'd love to hear your thoughts in the comments below!
