Tubolito S-Tubo Gravel Bike Inner Tube 700×30-40C 42mm Presta

S-Tubo-CX/Gravel Tube: Your Ultimate Lightweight Ride Companion

Tired of bulky spares hogging your jersey pockets? Meet the S-Tubo-CX/Gravel Tube—a game-changer for gravel cyclists and road enthusiasts alike. Designed to slip seamlessly into any small pocket or saddle bag, this ultra-compact spare isn’t just for emergencies—it’s built to handle daily adventures with unmatched versatility.

Why It Stands Out:
– Lightweight Precision: Weighs less than standard tubes while maintaining exceptional durability, thanks to its Thermoplastic Elastomer compound.
– Efficiency Boost: Engineered for lower rolling resistance, giving you an edge on long-distance rides or competitive gravel events.
– Tubeless Ready: Compatible with leftover sealant residues, so there’s no need to clean your rims before installation.

Specs That Matter:
– Valve Type: Presta Medium (41-55mm) for precise inflation control.
– Compatibility: Disc brake optimized, fitting 700×30-40 tires (ISO widths 30-40mm) on 622mm (29″) rims.

When To Reach For It:
Whether you’re tackling technical trails, commuting through urban chaos, or chasing KOMs on mixed-surface routes, this tube ensures you’re always prepared. Its smooth shaft design reduces friction inside your tire casing, prolonging inner tube life and enhancing ride comfort.

Why Choose S-Tubo-CX?
Compare it to traditional rubber tubes: same rugged reliability but lighter and faster-rolling. Unlike generic spares, this tube’s low-maintenance design works seamlessly with modern tubeless setups—no messy cleanups required after flatting mid-ride.

Stay ahead of the pack with gear that prioritizes performance without compromising on practicality. Perfect for gravel grinders, road racers, and anyone who values reliability on two wheels.
