The History of Tollwut gravity bikes:
Aljoscha Schmidt well experienced in welding bike frames for a big german bike manufactory started to handcraft his own DH bike.
The first prototyp in 2001:
He sold a few bikes which are still up to date with the performance and hard to get on the used bike market.
One who owns a frame doesn't sell it.
In 2004 Jens Böttner won on a Toolwut Ladyshapa the german official DH Series before the german champion Markus Klausmann (GHOST Bikes).
After a few years he stoped building the frame, because the trend went to monocoque frames, which were to expensiv with a small number of frames.
Later on a good buddy of Josch, Ralf Tröger a GHOST dual cup racer and Tollwut Ladyshapa rider finished his mechanical engineering study with his master thesis supported by Centurion Bikes.
The first prototyp bike - > Master thesis of Ralf Tröger
The first official Stonedigger presented by Centurion Bikes and Ralf Tröger at the EUROBIKE 2006 trade fair.
The knowledge of the kinematic is easy to explain with LEGO, pull the rope (chain) and you see the upper chassis stays still and the below one lifts.
-> You see, the usually constructed Chassis kill rear perfomance while speeding up the bike.
Centurion was not further interested to bring such a gravity bike in a serie.
Thats when Ralf and Josch found together again. Josch was based on his experience building DH Race bikes a hugh help to bring the bike to it todays quality and perfection.
Together they developed the Evolution 2 of the Stonedigga which was the rebirth of the brind Tollwut (eng.: rabies or canine madness)
