Gamux Bikes, designers of the only belt-driven gearbox mountain bike racing the UCI Lenzerheide World Cup DH this weekend, have two new mountain bikes under development. Featuring a unique cnc-machined rear-end that the Swiss brand has become known for, the Gamux trail bike delivers its 150mm rear wheel travel via a Horst-Link. Meanwhile, the 130mm travel Downcountry bike will see a full carbon construction, utilizing a lighter weight flex-pivot suspension platform.
Gamux Engineer, Pascal Tinner, gave us a run down of what’s to come in 2024. The Gamux downhill athletes, Lino Lehmann and Mike Huter, have been involved in testing the all-mountain prototype Prototype Gamux All-Mtn Bike
Designed around a 150mm travel rear-end, the Gamux Trail/All-Mtn Bike will take a 150mm or a 160mm fork. A carbon front triangle is paired with cnc-machined chainstays, seatstays, link and shock yoke.
Pascal tells us that Gamux really enjoy working with aluminum, especially as the cnc machining they can do is a really accurate production method. It allows them to fine-tune flex characteristics through varying the architecture of the stays.
To increase or decrease stiffness of the rear-end in any way is not simply a matter of adding or removing material; it would actually require a different geometry in the structure of the stays. Gamux is producing the carbon front triangle and machined swingarm and links in-house in Switzerland The initial prototype saw a C-shape pattern in the stays, but this produced a rear-end that was too stiff laterally, and so Gamux reworked the design […]
