With the Ion GPI, Nicolai has melded properly forward thinking geometry with a revolutionary drivetrain that does away with the derailleur. So does this add up to a bike that lights the way for things to come? Based on a test day aboard the strange beast, the answer to that question is both yes and no.
We’ve written before about the GeoMetron, the fruit of a collaboration between German frame builders Nicolai and the boundary-pushing boss of Mojo Suspension, Chris Porter.

In a nutshell, the GeoMetron takes the basic outline of Nicolai’s 155mm rear travel Ion 16 and pairs it to geometry that’s slack enough be on the more radical edge of current World Cup downhill bikes despite only running a 160-180mm fork and being firmly designed as a do-it-all trail bike. It also has a much longer reach than most bikes on the market paired to a very steep seat angle.
