Experience Machine from Helsinki: The Pelago Thórsmörk Reviewed
Note: Pelago provided me with the Thórsmörk for review at my request.
In many bike reviews – including my own – the focus is often on how much faster or lighter a bike is, how much more performance you can get out of it. That is certainly the trend, but it’s not everything. Bikepacking is really about the experience. And with all the posts and videos about new records on ultra rides, days of suffering, mental challenges and the glorification of Type Two Fun, we forget that it’s actually about having a great time on the bike, alone or with others. An adventure on two wheels, without time pressure and competition.
The Pelago Thórsmörk comes from exactly that direction. I first came across it three years ago and added it to my overview of interesting bikes. That’s why I was really excited to finally get to try it out in person.
Þórsmörk: A Name That Says It All
Pelago is a Finnish company from Helsinki, and the name Thórsmörk comes from Icelandic: Þórsmörk means “Thor’s Forest,” a nature reserve between glaciers and volcanoes. But what truly defines the place is this: Þórsmörk is only reachable via rough gravel tracks and glacial river crossings. Regular cars can’t get there. It takes off-road vehicles, or legs, or a good bike. Worth mentioning: the famous Laugavegur hiking trail ends right there.
Pelago didn’t choose this name because it sounds good. But because it describes what the bike is built for: places that don’t reveal themselves easily. Paths that are no longer paved roads. In short: a bike for adventure.
Steel, Trail and a Surprising Geometry
The Pelago Thórsmörk is a trail bike with a steel frame and fork. Geometry-wise it sits on the sportier side, with a stack-to-reach ratio of 1.31:1. The numbers are slightly deceiving, though – the bike rides remarkably relaxed and forgiving.
I’ve done several training rides on it and noticed: it can be agile when it needs to be. But its true element is controlled, comfortable rolling over roots and rocks.
That’s largely down to the steel frame, which takes care of ride comfort. It’s made from 4130 Cr-Mo and is double-butted. That means the tubes aren’t the same thickness throughout. At the ends, where the welds and the highest stresses are, the material is thicker – thinner in the middle. This saves weight compared to uniformly thick tubes without losing stiffness.
Pelago describes the frame as having modern trail geometry. That’s expressed primarily in the 66.5-degree head tube angle, combined with a long reach. This makes the Thórsmörk more stable on fast, demanding trails and descents. The front end sits quieter, the bike doesn’t get unsettled as easily. At the same time, the 432mm short chainstays keep it nimble enough for tighter corners and technical sections. The turning radius, as I would describe it in a car, is a bit larger than on my Monster Gravel, for example. You have to get used to that.
Like a Train on Rails
The Pelago doesn’t surprise you while riding, which is meant as a compliment, because that’s especially relevant when loaded. Cargo can make the handling of bikes worse, while the Thórsmörk compensates for that better. You ride in a slightly more stretched-out, sporty position, but the bike genuinely moves like a train on rails.
I was impressed by how well the bike climbs and had a lot of fun on my training rides in the “mountains” along the Elbe. On asphalt it rolls a bit slower, naturally, but once you hit terrain it comes alive. I had to adjust to the forgiving steering. It’s simply not as agile as on my Monster Gravel. But it always feels safe and controlled, and it’s great fun to charge down the hills on it.
The trail geometry gives the bike a slight chopper feel. The handlebar sits far forward, the front wheel pulls the line. At the same time you sit quite sporty and lean-forward. That’s not a contradiction and in my view, that’s exactly what defines the character of the Thórsmörk.
Pack Mule with Character: Weight and Mounting Points
What I really like about the Pelago Thórsmörk is the large main triangle and the steel fork with its many mounting options. The bike can carry a lot and has a system weight of 130kg.
At 14.3kg (in size S) it’s not light — but anyone who loves steel won’t be put off by that.
Rigid Fork as Standard – and What’s Possible
The steel fork looks at first glance like it’s from another era, since many manufacturers today combine steel frames with aluminium or carbon forks to save weight. But Pelago stays true to the material. And that comes at a price on the scales: the frame (size M) weighs 3.04kg, the fork 1.7kg. The frameset therefore comes to just under 4.8kg.
That said, the rigid fork can be swapped for a suspension fork with 120–140mm of travel (44mm offset) – which would likely also save some weight. Or you can fit a suitable carbon or aluminium fork. A dropper post is also internally routed (31.6mm, insertion length varies by frame size).
The frame features a UDH (universal derailleur hanger) for conventional derailleurs, as well as direct mount compatibility for SRAM Transmission.
The Thórsmörk is currently not available as a frameset, only as a complete bike. Pelago hasn’t ruled it out for the future, however, if demand justifies it.
The Build: Deore, WTB and Wide Tyres
The complete bike in this test comes with WTB wheels built around STi35 aluminium rims and 29-inch WTB Ranger tyres in 2.6-inch width. Maximum tyre clearance is 29×2.8″ (or 27.5×3.0″); with mudguards fitted, only 2.4-inch tyres will fit on 29″.
Shifting is handled by a 1×12 Shimano Deore mechanical groupset. Up front is a 32-tooth chainring, at the back a Shimano 10-51T cassette.
This makes the bike well prepared for riding with luggage. By contrast, many gravel bikes come with drivetrains that hit their limits once you add gear, and aren’t really adequate for off-road terrain.
The 780mm-wide JD riser bar also contributes to the comfortable ride feel, giving you real confidence through technical terrain.
And anyone looking to save some weight can certainly do so with a different groupset, lighter wheels or a different fork.
Geometry Twins: Comparison with the Sour Pasta Party
Now it gets interesting: if you’re looking for a comparable bike, the Sour Pasta Party is the obvious choice. In a direct geometry comparison (size L), the two bikes are near-identical: head tube angle 66.5° vs. 66.6°, identical BB drop, almost the same chainstay length. The Thórsmörk’s wheelbase is 30mm longer, which translates to slightly more stability and composure.
The Pasta Party is available either as a frameset (from €1,400) or as a complete bike with Shimano XT, with either a steel rigid fork or suspension fork. Building it up with a rigid fork and Shimano XT quickly gets you to €3,600 and above.
The Thórsmörk, by contrast, is ready to ride from €1,999, including Shimano Deore 1×12. It’s unfortunately not available as a frameset. But anyone who deliberately wants to ride rigid and doesn’t want to compromise on modern trail geometry gets significantly more for their money with the Pelago, and can still upgrade later.
For completeness, the weight comparison: 4.8kg for the Pelago frameset including fork; the Sour Pasta Party comes in at 4.04kg (frame 2.39kg + fork 1.65kg).
As a Bikepacking Machine: Everything You Need
For bikepacking, the Pelago has it all: the main triangle has room for a large frame bag, the handlebar offers plenty of space for a handlebar bag, cages can be mounted on the fork legs, and the seatpost has room for a rack or seat bag.
You can turn this sporty trail bike into an adventure machine for any terrain. And with a 130kg system weight there’s plenty of room for luggage.
You can also order matching racks straight from Pelago, such as the Pelago Front Rack Large or the Fork Racks for carrying gear on the fork. And if you like, Pelago also offers matching bags.
The chunky, grippy WTB Ranger 29×2.6″ are a natural tyre choice and perform well in terrain. On tarmac they roll a bit slower, of course. But you can always swap tyres to suit your preferred surfaces.
And with the Shimano Deore (32/10-51T) you have plenty of reserve for climbs with luggage.
Conclusion: The Experience Machine
Simply put: if you love steel, you’ll love the Pelago Thórsmörk. It’s an experience machine, not light, but it takes you reliably and far beyond paved roads.
In my view, the Pelago Thórsmörk is a bike for bikepackers who seek out terrain, for whom weight doesn’t matter and who put experience above times and performance. And for those who want to ride a brand that not everyone knows yet.
For €2,000 you get a ready-to-ride bike with a very solid spec. And anyone who wants more can upgrade with suspension fork, different wheels, different groupset.
If you’re still questioning whether 14.3kg of steel should really be carbon: Dominic Rivard has done the maths and the result is beautifully sobering.
