The Santos 4.29 is specially designed for bikers who love muddy grounds. And for bikepackers who like to get off the beaten track. It is light, fast and suitable for carrying lots of stuff. Equipped with the right carriers, you can easily take 25 kilos of luggage. A truly multifunctional adventure bike!
We have made the 4.29 very robust. Especially the versions with Rohloff or Pinion with belt drive are super strong and durable. With this set-up you can easily take muddy paths and collect dust all year round without having to renew your drive system.
No matter how tough the circumstances, the 4.29 is always ready to go. If you also opt for the hydraulic Magura Firmtech rim brakes, then you have the most low-maintenance mountain bike in the world.
Have fun on muddy paths and sandy hills. In all weather conditions. The Rohloff hub with internal gears and Gates carbon belt drive ensure that you only have to gently hose down the 4.29 afterwards.
Or even put it away with mud and all, no problem.
Enjoy mountain biking in the winter and a cycling holiday in the summer, possibly with fast racing tires. Or fit wide tires (2.35/60mm tires will fit easily) and you can bike straight onto the beach.
You don't need two or three different bikes. One bike fits all!
The 4.29 is light yet strong. You can take it with you on your next bikepacking adventure. An exciting off-road trip with your luggage strapped to the frame.
With a AdventureRack luggage carrier and a fixed steel fork with lowrider you can turn it into a serious adventure bike and conquer the world!
The only 29er mountain bike in the world with Magura FIRMtech rim brakes.
For speed demons who want enjoy fast downhills, the 4.29 is also available with disc brakes.
12 or 18 gears
You can also choose the Pinion gear system. This type of transmission will be supplied with belt drive, which makes it a super durable and low maintenance combination. By default we mount the Pinion gear box with 12 gears, but 18 speed is also an option.
Travel bikes with power
The 4.29 is designed with the future in mind. It is E-bike ready. This means the bike can be transformed into an E-bike whenever you wish to do so. A powerful feature, extremely flexible.
The 4.29 E-bike has a strong motor and a big battery for a large radius of action. We chose a modular system, to be flexible, now and later.
The strongest brakes with the most powerful braking power. Ready for long downhills. The Hope disc brakes have 4 pistons and extra large steel Santos (203 mm) and extra thick (3.5 mm) discs.
Or go for the hydraulic Shimano XT disc brakes with 180 mm steel Santos discs. Choose what suits you best.
The 4.29 comes with hydraulic FIRMtech brakes from Magura. These are robust, durable and as the name suggests, firm or powerful. They brake firmly and directly and are easy to dose. Even riders with smaller hands or little strength in their fingers can easily bring the 4.29 to a stop with the use of just 1 or 2 fingers. With the control wheel attached to the brake lever you can easily adjust the braking power; either more aggressively or with a more friendly stroke. Also in wet weather conditions.
The 4.29 has a raised front, which can accommodate both a fixed and a suspension fork.
We have developed the fixed front forks ourselves. These stable, aluminum or steel 29er forks are equipped with lowrider inserts, suitable for heavy-duty use. You can mount Son SL which keeps your lamp always straight and it guides the cables neatly in front of your frame. The aluminum version has inserts for 2 bottle holders.
Of course, the 4.29 is assembled with our extra strong travel wheels. They are handbuilt with the best rims on the market. Our hubs have 36 spoke holes and spoke nipples are secured.
The 4.29 fits tires up to 60 mm thick. This also gives you plenty of tire clearance with mudguards.
Tires up to 60mm fit in the 4.29 and even with mudguards this will give you plenty of clearance.
The 4.29 has a super strong fixed rear dropout. This way your wheel is always straight and you can easily remove it from your frame.
The rear dropout of the 4.29 is also suitable for a derailleur. With this non-fixed derailleur part you can easily switch to another transmission system. This way, the 4.29 will fit your needs now and in the future.
