Pinion 18 speed Gearbox - Eurobike 2011
Hello,
In the pinion preview on www.mtb-news.de is the reason why they are using a twist shifter instead of a trigger shifter explained.
“The reason why they are using a twist shifter is because of the needed movement radius of the cam shafts which are changing the gears in the gearbox. Altogether the cam shafts turn through 1020° between the smallest and the highest gear, for which reason the Bowden cable in spite of a gear ratio has to be pulled widely. This prevents the application of a real trigger shifter.”
P.S.: Sorry for my poor English-Translation
