Gravel | Snuitide

Gravel is the type of cycling that has grown fastest in Norwegian cycling friluftsliv over the past five to ten years. It is not a new discipline in the classic sense — people have ridden on gravel for over a hundred years — but it is a new category of equipment and a new way of thinking about the bike that opens up routes which used to sit in the gap between the road bike and the mountain bike. Tyre widths of 32–50 mm, drop bars, a lighter frame than a mountain bike, clearly wider than the racing bike — it is a combination that covers most of Norway’s gravel roads, forestry roads, and easy trail.

The big advantage of gravel is its range. On a typical gravel bike you can ride 100 km on tarmac and 50 km on gravel in the same trip without having the wrong equipment for part of it. That opens up routes which cross several types of terrain — Mjølkevegen, Numedalsruta, parts of the Pilegrimsleden — in a way that neither the road racer nor the mountain bike does.

What sets gravel apart from the neighbouring activities

Gravel sits between three other categories:

The road bike (racer) has tyres of 25–32 mm, drop bars, and is optimised for tarmac and speed. A weight under 8–9 kg is common. Gravel is wider, more robust, and 1–3 kg heavier — you give up a little speed to be able to ride on surfaces the racing bike cannot handle.

Cyclocross is gravel’s close relative — also drop bars, also wide tyres (33 mm typically), but optimised for short cross races in mud and over obstacles. Cyclocross has a steeper, more racing-oriented geometry; gravel is more comfort-oriented. A blurred line.

The hardtail mountain bike has wider tyres (2.2–2.6 inches ≈ 56–66 mm), flat bars, and fork suspension. The mountain bike gives better control on steep and technical terrain, but is slower on long gravel and tarmac stretches. Gravel is often quicker on long days; the mountain bike is better on trail.

For anyone new to cycling as an outdoor activity, the choice between gravel and the hardtail mountain bike is the most common one. Rule of thumb: if you want to ride long days with a mix of tarmac and gravel, gravel is better. If you want to ride steep trail and technical mountain-bike terrain, a hardtail is better. For many people, gravel is the variant that actually covers what they do most.

Geometry and tyre width

Two technical factors govern how a gravel bike behaves:

Geometry has gradually become slacker and longer over the past five years. Slack head tubes (71–73°) give better stability on uneven surfaces. A longer top tube gives more room for luggage (bikepacking) and better weight distribution.

Tyre width is governed by the frame’s clearance and the wheel size. Classic gravel:

32–35 mm — for gravel that is almost as smooth as tarmac. Light, fast, but poor grip on loose gravel
38–42 mm — the most common, the all-round choice for Norwegian gravel
45–50 mm — for uneven gravel, easy trail, a mix with mountain-bike terrain
50+ mm — really mountain-bike territory, but some gravel bikes take up to 55 mm

For a typical Norwegian gravel trip, a 40 mm tyre is the safe starting point. It covers gravel roads, forestry roads, and mild trail. Narrower is for special uses; wider is a compromise against rolling resistance.

Why gravel has grown

The gravel segment has grown quickly internationally and in Norway over the past 5–10 years. Three reasons:

The infrastructure. Norway has a lot of gravel — forestry roads, construction roads, old main roads that have been downgraded. With 40 mm tyres, a network of trails opens up that neither the racer nor the mountain bike has traditionally taken.

Long trips as a format. Gravel suits what is called «long distance» — multi-day trips, ultra-racing, bikepacking. Birkebeinerrittet can be ridden on gravel; so can many classic Norwegian races. Mjølkevegen is a gravel route.

Comfort over speed. A gravel bike is more comfortable over several hours than a racer on gravel. For people who ride for 4–8 hours at a stretch, that is the difference between a good day and one where the back complains.

For anyone who wants to extend into bikepacking, gravel is often the most pragmatic basis — you have one bike that covers both the everyday trip and the weekend trip.

Classic Norwegian gravel routes

Norway has many classic gravel routes, particularly in mountain and valley areas:

Mjølkevegen — 250 km between Vinstra and Gol, a classic gravel bikepacking route. The southern route is around 100 km, the northern route around 200 km, and they can be combined.

Rallarvegen — 80–82 km Haugastøl–Flåm. Built as a construction road for the Bergen railway, opened to cycling in the summer of 1974. A classic above all others, it works well on gravel.

Numedalsruta (National Cycle Route 5) — 243 km from Smådøldalen to Larvik. Tarmac and easy gravel, a classic gravel trip.

Aurlandsfjellet (Snøvegen) — 48 km Aurland–Lærdal, with its highest point at 1,306 m above sea level. More tarmac than gravel, but a perfect gravel route for fjord cyclists.

Pilegrimsleden Gudbrandsdalsleden — 632 km Oslo–Trondheim. A mix of tarmac and gravel, can be ridden on a gravel bike.

Setesdal and Telemark have a large network of local gravel routes on forestry roads and old construction roads — check local tourist sites for maps.

Lofoten by bike along the E10 — 160 km Fiskebøl–Å. Mostly tarmac with about 20 km of gravel.

For anyone who wants to explore: Komoot is the dominant tool for gravel route planning in Norway. Trailforks covers mountain-bike trails better, while UT.no and Statens vegvesen’s national cycle routes offer curated route options.

The way in

For anyone new to gravel:

Start with a bike you have. A mountain bike with narrower tyres or a touring bike can get a long way on gravel routes before you invest in a specialised gravel bike.

Long day trips as a basis. Gravel cycling is about keeping up a pace over several hours. Start with 50–80 km day trips to build stamina.

Learn to pack. Bikepacking packing is just as relevant for gravel as it is for mountain-bike-based trips.

Test before you buy. Many rental places in the mountain towns and around the country hire out gravel bikes by the day. Two days on a good gravel bike tell you more than several months of guessing.

Season and conditions

The Norwegian gravel season:

April–May — the lowlands are often clear in April, the mountain roads somewhat later
June–September — the core, long days, settled conditions
October–November — still rideable in the lowlands, but shorter days
November–March — gravel in winter is a special variant, requiring studded tyres or a fat bike

Norwegian gravel roads change character with the weather. A road that is fast and firm when dry becomes slimy and demanding in rain. Check the weather forecast before longer trips, and consider whether an alternative route with more tarmac might be better during rainy periods.

Safety

Gravel cycling safety is largely the same as ordinary cycling safety, with a few particular features:

Helmet always — including on long tarmac stretches
Visibility — drop bars and a low riding position can make you less visible to cars. Yellow or orange clothing helps.
Brakes on the steep — long descents on gravel call for a different braking technique than tarmac. Work the rear wheel, weight back, slow down. Braking technique on the steep goes through it.
Punctures on gravel are more common than on tarmac — practise repair before your first long trip

For long trips in remote areas: contact details, extra food and fuel, and a map app that works offline (Komoot Pro, Trailforks Pro) are sensible to have.

Next steps

If gravel is new to you: do one long day trip (60–80 km) on a local gravel road to see how it feels. It is a quite different rhythm from racing on the road and a different use of energy from the mountain bike.

If you have done day trips and want to go further: build up to bikepacking — gravel and bikepacking go together very well.

For established routes: Mjølkevegen is classic first-time bikepacking on gravel. Numedalsruta is a good next step for longer multi-day trips.

For equipment: bikepacking packing for packing systems that work on gravel, and trail mechanics for the practical side.
