ICB 2.0

The Project

The ICB2.0 ist the second mountainbike-frame developed by the Internet Bike Community. In cooperation with German brand Alutech-Cycles hundreds of users discussed and evolved the idea of a modern trailbike, perfectly fit for singletracks. Stefan Stark had the pleasure to design the wishes and demands of the community. The result is a versatile and longlasting bicycle, by riders for riders.

We are using big, long-lasting angular contact bearings made by SKF. A world’s first is the fact, that they are preloaded without putting extra stress on the frame structure, easing adjustment and increasing reliability.

Geometry

The geometry of the ICB2.0: Short rear-end, rather long and really low main-frame to give you the opportunity to choose between two frame-sizes.

History

“Wouldn’t it be awesome if we’d show our readers the bicycle-development process by having them develop a bike?” – that’s what MTB-News.de editor Maxi Dickerhoff asked at a christmas celebration in 2011. Stefanus Stahl – as him a member of the MTB-News.de team – started to work on the task, and what sounded crazy became reality soon after.

ICB 1

Stefan Stark had already asked our readers while developing the original Fanes enduro – in our Alutech supportforum – what are their wishes, their ideas? This showed he’d be a great match for our community-bike. So we got him on team, as well as Carver Bikes and product manager Sebastian Tegtmeier. We nannounced the topic, and it was an immediate success. Every step was disscussed online, and already at Eurobike 2012 the first prototype of the ICB01 – welded by Alutech-owner Jürgen Schlender – could be seen.

In summer 2013 the bike was ready for sale as a frame only and as a complete bike. Ever since Max Schumann, Carver-pro-racer, has been racing the bike around the globe in the Enduro World Series and mega-avalanche races.

ICB 2.0

2014 the team of the ICB01 met and decided to do it again. Sebastian is now working for Alutech, as is Stefan, so it made sense to have Alutech become the next industry partner. So we started of: ICB 2 – powered by Alutech.
