I had one. Please take my word on this . . . Keep the bottom end and those gears in there tight and greased up.
There is what I feel is a design flaw in that there isnt enough "meat"(?) on the gears and when/if they wear, the
bottom bracket becomes a symphony of crunchy sounds_ gears slipping teeth, etc . . .
Otherwise, its cool to ride with no chain grime and spray.
I liked the quiet hummmmmmm noise it made going down he road.
They have re vamped the meat. And I have found out that the crunching noises people must have is from the shaft housing rub bin against the frame b.b.!
Alittle lube and there is no noise. I first heard the noise and knew it wasn't a gear , sprayed wd40 down seat tube and the noise stopped.
And its a great bike PERIOD. Please look into a super Bicycle www.dynamicbicycles.com
"The Synergy Road 8 is a performance road bike that uses"................a chain.
It would be super cool if the drive shaft tube were structural, and they could eliminate the chain stay on that side!
