# Road bike vs gravel bike: which should I buy?

> A road bike is faster on tarmac with narrower tyres and more aggressive geometry, while a gravel bike is more versatile with wider tyres that handle mixed surfaces including gravel, towpaths, and light trails. If 80%+ of your riding is on paved roads, choose a road bike. If you want to explore varied terrain or go bikepacking, a gravel bike is the better all-round choice. Gravel bikes are the fastest-growing bike category in the UK.

## Speed and performance

Road bikes are 2-5 km/h faster on smooth tarmac thanks to narrower tyres (23-28mm), lighter weight, and more aerodynamic positioning. Gravel bikes use wider tyres (35-50mm) and more relaxed geometry, sacrificing some road speed for comfort and capability on rough surfaces.

## Versatility and terrain

Gravel bikes can handle everything from tarmac roads to gravel paths, canal towpaths, forest tracks, and light singletrack. Road bikes are limited to paved surfaces, even rough B-roads can be uncomfortable. If you want one bike that does it all, gravel wins.

## Comfort and position

Gravel bikes have a more upright riding position, longer chainstays for stability, and wider tyres that absorb bumps. Road bikes put you in a lower, more aggressive position for aerodynamics. For long rides on mixed terrain, gravel is more comfortable; for racing or fast group rides, road is better.

## Related questions

### Can I use a gravel bike as a road bike?

Yes, gravel bikes work well on roads, just 2-5 km/h slower than a pure road bike. Many riders use a gravel bike as their only bike, swapping to narrower tyres for road-only days.

### Is a gravel bike good for commuting?

Excellent. Gravel bikes handle potholes, cycle paths, and wet conditions better than road bikes. The wider tyres and disc brakes make them reliable all-weather commuters.
