New territory: For the first time, bike tuner Gustav "Dangerholm" Gullholm refined a women's model. The Contessa Addict Gravel from Scott served as the basis.
Bike tuner Gustav Gullholm, better known as Dangerholm, has struck again. His latest work of art is a refined gravel bike based on the Scott Contessa Addict Gravel. The Scandinavian also gives TOUR a preview of his first road bike project.

After a tuned Addict Gravel last year, Dangerholm, who actually specialises in tuning mountain bikes, presents his second gravel bike. With this tuning model, the extroverted Swede with XXL-sized thighs is nevertheless breaking new ground: for the first time, he has spiced up a bike for women - and got his girlfriend Pernilla Eriksson on board. "Women's cycling is on the rise, so it was finally time for it," says Gullholm.

Based on the Contessa Addict Gravel, the duo designed an exclusive one-off that, according to Gullholm, weighs 7.5 kilos in size S. For comparison: the Top model of Scott's gravel platform weighed in at 8.3 kilos (size L) at TOUR. As befits a genuine Dangerholm model, the Dream Build features a host of expensive high-end components, which are also matched to the rose/black colour scheme.

Exclusive drivetrain on the Dangerholm

Even the single drivetrain attracts attention. The rear derailleur (SRAM X01) is pimped with an oversized derailleur cage (Ceramicspeed OSPW Cerakote), whose gear wheels are said to be more durable than conventional models thanks to a ceramic coating. Cost for this alone: 749 euros! The gear ratio is extreme thanks to the small chainring (Garbaruk, 42 teeth) and the huge MTB cassette (Leonardio General Lee, 9-50 teeth).

Components from Germany

Another highlight are the wheels - a popular tuning topic not only among hobby mechanics. Dangerholm relies on German engineering expertise. Spokes - in eye-catching pink - and hubs come from the Saxon company Wheel manufacturer PiRopewho made a name for himself with braided spokes and presented a wheelset for road and gravel bikes for the first time in 2020. "I've already found that PiRope wheels minimise vibrations slightly better than conventional models on MTBs," says Dangerholm. The bike tuner also relies on products "Made in Germany" for the brake system: brake calipers and discs come from Trickstuff.

New project based on the Foil RC

And the next project is already waiting. For the first time, Dangerholm is refining a road bike, an aero bike to be precise. Scott is providing him with the Foil RC, the TOUR has already been able to test the top-of-the-range equipment. "Before we have the final version, we have to fine-tune it. This concerns the gear ratio and seating position, among other things," explains the Scandinavian.

However, the first glance at its version already reveals a lot. The rear derailleur comes from SRAM with an XPLR cassette, while the wheels are made by Franconian lightweight construction specialist Bike Ahead Composites. Dangerholm also reveals that the crankset will come from a 3D printer. "And the white paintwork will also come off, of course," says the bike tuner. The model is set to be officially unveiled in winter or spring.
