What is Tubeless?
As the name suggests, going tubeless means ditching the inner tubes inside your tires. Instead, the tire itself creates an airtight seal against the rim. To make this possible, you'll need tubeless-specific tires, valves, rim tape, and sealant.
Why should You go Tubeless?
There are several benefits to switching to a tubeless setup, as compared to traditional tire-tube combos. Firstly, you can run lower pressures without worrying about pinch or snakebite punctures. No real snakes are involved, but when the rim pinches the inner tube against the tire, it creates two small holes that resemble snakebites. Snakes on the trail! Not really though. But going tubeless means no more snakebites! Yay.
Other types of punctures are also less likely. The tubeless sealant, which is like a runny glue, self-seals small cuts and punctures from thorns and sharp rocks. You might not even notice you had a small puncture until after your ride.
Going tubeless also improves your ride quality. Lower tire pressures increase grip and comfort, while eliminating the tube reduces friction between the tire and the wheel, leading to lower rolling resistance and a smoother ride.
So, why not go tubeless?
