Mounting the 70 tooth chain wheel, SRAM X7 Front Derailleur and gear shifter handle was strait forward and was done in about 45 minutes.
I had to ad 7 chain links because of the bigger chain wheel.
After some testing I tried to drive as fast possible. The top speed at this moment are 60 km/h witch is a big improvement. My top speed before was about 45 -50 km/h.
I didn't find time to build the new head wrest now.
All most finished building the RaptoBike. I mounted a pair of Electron 16 LED System head light on a self done aluminum bracket. Now I'm waiting for the 70 tooth chainring to improve my top speed.
I mounted a pair off Cranck brothers Candy SL pedals.
I did't like the pedals with SPD binding there was on on the bike when I get it.
I will build my oven headrest because the one I mounted are in conflict with my helmet and not comfortable because the angel can not be adjusted enough.
