One tube for road rides, gravel roads, and everything between
More riders than ever are riding both asphalt and gravel on the same bike, often in the same week. A loop that starts on smooth pavement and turns onto a gravel road no longer means changing bikes; it means the equipment has to handle both.
This road and gravel tube is built for exactly that kind of riding.
Why one tube for two surfaces
The line between road and gravel bikes keeps blurring. All-road bikes, gravel bikes, and endurance bikes all lean on the same idea: a platform that's fast enough on pavement and comfortable enough when the surface roughens. For riders who run that kind of setup, carrying a separate tube for each surface is unnecessary. One tube that covers both is the practical answer.
That's the segment this tube is aimed at. Not a dedicated race tube, not a heavy-duty trail tube, but a versatile option for the ride that mixes surfaces.
What mixed-surface riding asks of a tube
A road and gravel ride is a moving target. You spend time on pavement, where rolling and pressure matter. Then you hit gravel and hard-packed dirt, where the tube has to shrug off stone chips and small impacts. The demands change within a single ride:
- Smooth rolling on asphalt, without a dead feel
- Enough resilience for gravel chatter and loose stone
- A pressure range that works for both a fast road pace and a rougher gravel pace
- A tube that holds air over long, mixed days
- A spare that fits a road jersey pocket or a small bag
TPU fits that brief better than most. It saves weight and packs down small, while holding pressure well enough that the tube behaves consistently from the first mile to the last.
What it gets you
Lightweight TPU construction that cuts rotating weight on both surfaces
A compact folded size, so it carries easily as a spare on road or gravel rides
Reliable air retention that holds pressure across a long mixed day
Compatibility across road, gravel, and all-road platforms
A practical everyday choice for riders who switch routes often
It's not tuned to chase the last gram like a race tube, and it's not built as armor like a trail tube. It's the versatile middle, which is exactly what mixed-surface riding rewards.
Sizes and fit
Road and gravel wheels run on 700c rims, with tire widths that range from narrow road tyres up to the wider gravel sizes. We match the tube to your tire, so tell us your tyre width and rim, along with your valve type and preferred valve length, and we'll confirm the fit before you order.
Where it fits
Mixed-surface and endurance rides
All-road and gravel bikes
Adventure cycling and weekend exploration
Commuting that mixes tarmac and paths
Any rider running one bike across several surfaces
An honest note on tubeless
Gravel riders who ride stone-heavy routes often go tubeless for puncture protection, and that's a fair call. If you'd rather stay with tubes, this is the tube to run on both surfaces, and it cuts the weight and bulk of a conventional road tube without locking you into one kind of riding.
OEM and wholesale
TUBENOX supplies this tube under private label to bicycle brands, distributors, and wholesalers worldwide. Custom branding, colors, valve specs, retail packaging, and bulk supply are all available, and samples come before you commit to volume.
FAQ
Can this replace separate road and gravel tubes?
For many riders, yes, as long as the tube matches the tire width. One tube covers both surfaces.
Is it suitable for all-road bicycles?
Yes. It's aimed squarely at all-road and gravel platforms that mix pavement and dirt.
Is it lighter than a conventional road tube?
TPU generally saves a meaningful amount of weight and packs down much smaller than a butyl tube.
Can it be carried as a spare tube?
Yes. The compact TPU design stores easily in a jersey pocket, saddle bag, or frame bag.
Does it hold pressure on long rides?
Yes. TPU retains air well, so pressure stays where you set it over a long mixed day.
Is it for racing or for everyday riding?
It's a versatile option, not a race-optimized one. For smooth, race-focused road riding, a dedicated lighter tube may suit better; for mixed surfaces, this is the pick.
What sizes does it cover?
It's built for 700c road and gravel wheels, matched to your tire width. Send your tire and rim and we'll confirm.
Do you support OEM and wholesale?
Yes. Private label, custom branding, and wholesale supply are all available for brands and distributors.
