Product Details

Overview & Technology

Michelin's Aircomp Ultralight Butyl is built for riders who chase every gram without sacrificing reliable air retention. Constructed from a thin, high-grade butyl compound, the Aircomp balances low weight with the proven impermeability of butyl rubber — the go-to material for consistent pressure during long efforts and races. The tube's construction emphasizes a pared-back wall thickness and precision molding to hit a road-racing weight target (typical 78g for the 700x18-25C variant). A removable Presta valve core and smooth, non-threaded valve shaft simplify inflation with CO2 cartridges, track pumps, and allow easy addition of sealant if desired.

Key Features & Real-World Benefits

Lightweight performance: At just ~78g for the 700x18-25C size, riders feel reduced rotating mass for snappier acceleration and quicker climbs. The ultralight construction is ideal for criteriums, road races and any situation where every gram matters. Removable valve core & valve length options: The removable Presta valve core (available in 48mm, 60mm and 80mm lengths across SKUs) lets you use CO2 cartridges without restrictions and makes adding sealant straightforward. Longer valve options are provided for deep-section rims and aerodynamic wheelsets. • High-grade butyl rubber for excellent air retention • Non-threaded valve shaft for smooth rim fit • Multiple width and valve length SKUs to match tires and rims

Fit, Compatibility & Technical Notes

The Aircomp Ultralight Butyl is made for 700C road wheels and comes in size ranges to cover common tire widths: 700x18-25C, 26-32C and 33-46C depending on the SKU. Choose valve length based on rim depth — 48mm for shallow rims, 60mm for mid-depth, and 80mm for deep-section aerodynamic rims. Please note: this tube is not thorn resistant. While the removable core makes adding sealant possible for extra puncture protection, the tube’s ultralight walls prioritize weight savings over puncture reinforcement. Non-threaded valve shafts seat cleanly in most rims but check your rim's valve hole and whether you want a plastic valve nut for extra security.

Who It's For

The Aircomp Ultralight Butyl is aimed at road racers, fast group-ride riders and climbing specialists who prioritize low weight and sharp handling. If you race criteriums, tackle long hill climbs or pair lightweight tubes with high-performance wheelsets, this tube delivers measurable gains. If you frequently ride rough, debris-strewn roads or need maximum puncture resistance for daily commuting, a thicker butyl tube or puncture-resistant model may suit you better. For racers wanting to run sealant and quick CO2 refills, the removable valve core is a practical advantage.

Frequently Asked Questions

How do I choose the right valve length?

Pick the valve length to match your rim depth: 48mm for shallow rims, 60mm for mid-depth rims, and 80mm for deep-section aerodynamic wheels. Measure from rim bed to outer rim edge to confirm clearance for pump heads or valve extenders.

Can I use sealant with this butyl tube?

Yes — the removable valve core makes it easy to add a small amount of sealant for extra puncture protection. Keep in mind the Aircomp prioritizes low weight over puncture-resistance, so sealant can help but won't fully match dedicated thorn-resistant tubes.

Is this tube suitable for tubeless wheels?

This is a standard inner tube for clincher tires and is not a tubeless product. Use only with clincher tires and rims designed for inner tubes. For tubeless setups, choose tubeless-specific tape and valves instead.

What tire widths does the 78g spec apply to?

The ~78g weight refers to the Michelin Aircomp Ultralight Butyl in the 700x18-25C configuration. Other size variants (26-32C, 33-46C) will have different weights commensurate with larger diameters and wall area.

Can I inflate with CO2 cartridges?

Yes — the removable valve core allows for rapid CO2 inflation. After using CO2, ride briefly and top up with a track pump if you need precise pressure, since CO2 leaks faster through butyl than compressed air from a pump.

Is this tube thorn resistant?

No. The Aircomp Ultralight Butyl is not designed with a thorn-resistant layer. If you regularly ride roads with glass, thorns, or rough debris, consider a puncture-resistant tube or adding sealant.

Buying Guide

Choose an inner tube by matching wheel diameter (700C), tire width range and valve length for your rim depth. For race setups pick the 18–25C Aircomp to maximize weight savings; for wider road or light gravel tires select the 26–32C or 33–46C SKUs. Decide whether ultralight performance outweighs puncture protection. If you want reduced rolling mass and quick accelerations, Aircomp is a strong choice. If you need more puncture resistance for daily training, pick a heavier-duty butyl tube or add sealant (using the removable valve core) to strike a balance.
