Tubeless has become the default tire system on most new complete road bikes as of 2026. Default doesn't mean automatically correct for every rider. Here's what actually changes, and where clincher remains a legitimate, deliberate choice.

| Factor | Clincher | Tubeless |
|---|---|---|
| Small puncture resistance | None built in; a puncture is a flat | Sealant plugs most small punctures while riding |
| Setup complexity | Simple, works with almost any rim | More involved; needs a tubeless-compatible or tubeless-ready rim and tire |
| Ongoing maintenance | None beyond normal tire wear checks | Sealant needs topping up every 2-4 months |
| Roadside repair difficulty | Straightforward tube swap | Plug usually works; tube-inside-tubeless is messier if not |
| Comfort at lower pressure | Good | Slightly better, tubeless tolerates lower pressure without pinch flats |
Independent lab testing has measured roughly 1-2 watts per tire of savings for tubeless over an equivalent clincher-and-tube setup at the same pressure. Across two tires, that's a few watts total, real but modest, and it matters far more to someone racing at the margins than to a rider who isn't chasing seconds.
Sealant dries out. Depending on climate and how often the wheel is ridden, that can happen in as little as two months. A rider who sets up tubeless once and never checks it again is, within a season, effectively riding an unsealed tire without realizing the protection is gone. This is the single biggest reason tubeless disappoints some riders: it's not a "set and forget" upgrade the way it's often marketed.
