To go bike touring with panniers you need three things: a rear rack that can take the load (good steel ones are rated for 55 lb, or 25 kg, or more), two rear panniers of about 20 liters, and low gearing, because with 44 lb (20 kg) on board you climb a lot slower. If you’re carrying a tent, sleeping bag and stove for several weeks, add a low front rack with two more small bags. With that load, a 43-mile (70 km) day with 3,280 ft (1,000 m) of climbing is about 4.5-5 hours in the saddle.
If you’d rather travel light on gravel roads without racks, see the guide to bikepacking.
Racks: rear and front
The rack does the hardest work on a tour. Look at three specs: max load, material and tube diameter (the panniers hook onto it).
| Model | Position | Weight | Max load | What it’s for |
|---|---|---|---|---|
| Tubus Logo Evo | Rear | 866 g (1.9 lb) | 57 lb / 26 kg (tested to 88 lb / 40 kg) | Long tours, with two heights for the bags |
| Tubus Tara | Front low-rider | 603 g (1.3 lb) | 40 lb / 18 kg | Front bags at axle height |
| Tubus Duo | Front low-rider | 658 g (1.5 lb) | 33 lb / 15 kg | Forks with a mid-blade mount |
Figures from the Tubus spec sheets, checked October 2026.
- Steel or aluminum. Steel (chromoly or stainless) weighs a bit more, but almost any shop can weld it if it breaks far from home. Aluminum is lighter and cheaper, and usually rated for less.
- Mounts. The rack bolts to the dropouts and seatstays. There are adapters for bikes without mounts, but not for heavy loads.
- Heel strike. With short chainstays, your heel hits the pannier as you pedal. Racks that hold the bags farther back, or narrower panniers, solve it.
Panniers: capacity and load
A standard rear pair gives you 40 liters (20 L each). The Ortlieb Back-Roller, one of the most popular, weighs 950 g (2.1 lb) per bag and is rated for 20 lb (9 kg) per bag. Up front, smaller bags are used: the Sport-Roller holds 14.5 L, weighs 795 g (1.8 lb) and is also rated for 20 lb; Ortlieb recommends it for front low-riders.
| Setup | Volume | Bags’ max load | Type of trip |
|---|---|---|---|
| 2 rear | 40 L | 40 lb (18 kg) | Indoor lodging every night, one- or two-week trips |
| 2 rear + handlebar bag | 45-50 L | 40 lb + the handlebar bag | Same, with essentials within reach |
| 2 rear + 2 front | 69 L | 79 lb / 36 kg (the rack limits you first) | Camping, cooking, long trips or far from stores |
Having room for 69 liters doesn’t mean you have to fill it: you pay for every pound on the climbs.
How to distribute the weight
- Heavy items low and close to the axle. Food, spare water, tools and cooking gear at the bottom of the panniers.
- More in back than in front. The rear wheel already carries most of your weight and the steering stays light. Front bags are for the second tier of gear.
- Up front, always low. A low-rider rack puts the bags at the height of the wheel axle, where they stabilize the bike. High front bags make the steering twitchy.
- Left and right, the same. Weigh both panniers before you leave: a 4-7 lb (2-3 kg) difference shows up in every corner.
- Light, bulky items on top. Sleeping bag and pad strapped to the rear rack, without exceeding its max load.
- What you use often, within reach. A handlebar bag for your phone, wallet, ride food and sunscreen.
Gearing: this is the key
With a load, the flats barely change and the climbs change a lot. According to our power model (a 165 lb rider, a 33 lb bike, 44 lb of gear, upright position), on a 6% grade you climb at 4.5 mph (7.3 km/h) at 150 W and 3.6 mph (5.9 km/h) at 120 W. To pedal at 70 rpm at those speeds you need:
| Power | Speed on 6% | Gearing for 70 rpm |
|---|---|---|
| 150 W | 4.5 mph (7.3 km/h) | 21.7 gear inches (1.73 m) |
| 120 W | 3.6 mph (5.9 km/h) | 17.5 gear inches (1.40 m) |
And here’s what a few combinations give you with 700x40 tires:
| Combination | Gearing | Cadence at 4.5 mph | Cadence at 3.6 mph |
|---|---|---|---|
| 34 x 34 (road compact) | 27.5 gear in (2.20 m) | 55 rpm | 44 rpm |
| 31 x 36 (2x gravel) | 23.7 gear in (1.89 m) | 64 rpm | 52 rpm |
| 26 x 34 (touring small ring) | 21.1 gear in (1.68 m) | 72 rpm | 58 rpm |
| 30 x 51 (1x mountain) | 16.2 gear in (1.29 m) | 94 rpm | 76 rpm |
The takeaway: a road compact is too tall for touring with panniers in hilly country. The sensible choice is a 26-31T small chainring with a 34-36T cog, or a mountain drivetrain. Compare yours with the gear ratio calculator, which opens from the button above already set to 110 kg (243 lb) total and 6%, and dig deeper in the best gearing for climbing.
Realistic daily mileage
A 43-mile (70 km) day with 3,280 ft (1,000 m) of climbing (10.4 miles of climbing at 6%, the same descending and 22.8 miles of flat), with 44 lb (20 kg) of gear:
| At 150 W | At 120 W | |
|---|---|---|
| Climbs | 2.3 h | 2.8 h |
| Flat | 1.5 h | 1.7 h |
| Descents (averaging 15.5 mph / 25 km/h) | 0.7 h | 0.7 h |
| Moving time | 4.5 h | 5.2 h |
A 15.5 mph average on descents is a conservative assumption with a loaded bike. On top of those hours come breaks, meals, grocery stops and the odd mechanical: a day like that easily takes 7-8 hours.
So, with panniers:
- First few days: 25-35 miles (40-60 km). Your body is adapting to many hours in a row in the saddle.
- Cruising: 30-55 miles (50-90 km) a day, depending on climbing. On flat ground with a tailwind you can top 60 miles (100 km).
- A rest day every 5-7 days. To do laundry, check the bike and keep fatigue from piling up.
- Measure climbing, not just miles. 37 miles with 4,900 ft of climbing is harder than 62 flat miles. Work out the hard sections with the climb time calculator.
The bike: what to check before you go
- Wheels: 32 spokes or more and 35-50 mm tires. Set pressure for the total weight with the tire pressure calculator: with 44 lb more, the right pressure goes up.
- Brakes: new or nearly new pads. With 240-265 lb (110-120 kg) between rider, bike and gear, long descents punish brakes much harder. If you feel them fading or the lever comes back to the bar, stop and get to a shop before descending further; how to check them is in disc brakes.
- Drivetrain: chain measured and cassette not worn (see when to replace your chain).
- Rack bolts: with threadlocker, and rechecked after the first day.
Common mistakes
- Exceeding the rack’s max load. It breaks in the worst place: far from home with everything on it. Carry zip ties and a spare hose clamp.
- Leaving without testing the loaded bike. Do a day ride with all your gear and a real climb.
- Carrying only front bags. All the load up front makes the steering very heavy.
- Planning days as if you were unloaded. With 44 lb and the same power, a 6-8% climb that takes you 30 minutes takes about 36, and on a tour you won’t be riding flat out.
- Forgetting water in summer. In the desert West and other remote areas there can be long stretches with no services: carry capacity for 2-3 liters, or more.
- Leaving the loaded bike unattended. Always take the bag with your ID and money.
Frequently asked questions
How much weight can a rear bike rack hold?
It depends on the model and is stamped on it. The steel Tubus Logo Evo is rated for 57 lb (26 kg) (the manufacturer tests it to 88 lb, or 40 kg); the Tubus Tara front rack, 40 lb (18 kg). Cheap aluminum racks are often rated at 44-55 lb (20-25 kg): check the number before you load up.
How many miles a day do you ride bike touring?
With panniers, 30 to 55 miles (50-90 km) is typical. With 44 lb (20 kg) of gear at 150 W, 43 miles with 3,280 ft of climbing is about 4.5 hours of moving time; at 120 W, about 5.2 hours. Add breaks, meals and photos on top.
How should I split the weight between front and rear panniers?
More in back than in front, and up front only on a low-rider rack, with the bags at axle height. Heavy things low and close to the wheels; never exceed each bag's rating (20 lb, or 9 kg, for Ortlieb) or the rack's.
What gearing do I need for touring with panniers?
To climb a 6% grade at 70 rpm with 44 lb of gear you need about 22 gear inches (1.73 m) at 150 W and 17.5 gear inches (1.40 m) at 120 W. A 31x36 with 700x40 tires gives 23.7 gear inches; to get below 19, you need a 26-30T small chainring with a big mountain cog.
Can any bike carry panniers?
It needs rack mounts on the dropouts and seatstays (or on the fork for a front rack), heel clearance and, ideally, tires 32 mm or wider. Touring bikes and many gravel bikes have them; almost no road bikes do.
