Gravel equipment for beginners: the right tire width, the optimal low tire pressure and the minimal repair kit – so you start safely and comfortably.
"What do I really need to start gravel riding?" – the honest answer: far less than the shop wants to sell you. A bike with 35–45 mm tires, the right (fairly low) tire pressure, a helmet and a small repair kit – that's it. And the most expensive beginner mistake costs you nothing to fix: too much air in the tire. On loose surfaces you often roll faster and always more comfortably with a wider tire at lower pressure, because the tire "swallows" stones instead of bouncing off them.
It sounds paradoxical but it is lab reality: every tire has a "breakpoint" – a pressure above which rolling resistance on rough ground no longer drops but rises again. The good news for you as a beginner: the best upgrade for your first gravel setup is free and it is called letting air out. This guide gives you the starter list and the right numbers – ready to ride in 20 minutes.
Think about where you ride 70 % of the time. Fine gravel and lots of tarmac: 38–40 mm. Roots, coarse stones, forest trails: 42–45 mm. But wider is not automatically faster – on tarmac more width costs aerodynamics, so tire choice is always a terrain compromise.
As a starting value for ~70–75 kg system weight on 40 mm tubeless tires: about 40 psi (≈2.8 bar) front, 2–4 psi more at the rear. If you run wider (45 mm), head toward 30–36 psi. Work down in 0.2 bar steps: low enough to roll planted and quiet, but without the rim bottoming out in corners or over edges.
Practice a tire change once at home in the dry. Pack a spare tube (even with tubeless, as backup), levers, multitool and pump on the frame – compact in a frame or saddle bag.
Roughly check saddle height: at the lowest pedal position your knee should stay slightly bent (target around 25–35° knee angle) – this protects the knees and pedals more efficiently. Gloves on, elbows loose: both dampen the vibration that is much higher on gravel than on tarmac.
Mount two bottles. For rides over one to two hours, bars or gels belong in your jersey – the details on amounts come in the nutrition guide, but "nothing on board" is the classic that ends rides.
A helmet is non-negotiable. Before every ride check tire pressure, brakes and quick-releases or thru-axles. Ride defensively on loose ground, brake early and gently – especially the rear – and keep a safe distance. On remote routes always carry a phone, some cash and enough water. And tell someone where you are riding.
After every ride, note your tire pressure and how the bike felt (0.2 bar too hard? too soft in corners?). After three or four rides you will have found your personal breakpoint – the narrow pressure zone where your tire rolls fastest AND most comfortably. That number is worth more than any expensive upgrade.
As a rule of thumb for around 70–75 kg on 40 mm tubeless tires: about 40 psi (2.8 bar) front, slightly more at the rear. With wider tires (45 mm), more like 30–36 psi. Work down in small steps until the tire rolls planted without bottoming out in corners. Less pressure usually means more grip and comfort on gravel.
For mixed terrain with lots of tarmac, 38–40 mm is the best all-rounder. For rough, rocky trails go to 42–45 mm; for fast smooth gravel, 35–38 mm is enough. Remember: wider rolls better on rough ground but costs a little aerodynamics on tarmac – the choice is always a compromise.
Tubeless is a clear advantage on gravel: the sealant closes small holes instantly, and you can run lower pressure without risking pinch flats (snakebites). Still, always carry a spare tube as a backup. If the setup feels too fiddly, good tubes are perfectly fine to start with.
No. If your existing road or cyclocross bike takes tires from about 35–38 mm, you can ride right away. Start with the bike you have, gain experience on easy gravel paths, and decide later whether a dedicated gravel bike really covers your routes better.
