Are there any cranks 3 cm longer than 170s?

I don't usually fret about BB height on my 650b conversions, but use 170 mm cranks. However, adding 1-3 cm of crank length would have me concerned enough to not recommend it. I've scraped road twice in thousands of miles with SPD pedals (sorta bounced the pedal off the road--not any danger of crashing). Most of my miles have been with a 650b Ram.

Besides, the benefit for 650b conversions (for me) is to gain in max tire width, which is beneficial for the plush ride and safer in terms of handling cracks and potholes in the road. I can't tell if you are thinking about converting your Hunq or Atlantis, but it doesn't seem to be of benefit in terms of tire width, because those bikes can handle wide tires already?

    Miss Ryan, I agree that tragic is much better than fatal when
    discussing accidents of any kind: whether people, bike or cars are
    involved.  Steel bikes  usually repairable, people rehabilitated,
    newer cars written off by insurance companies.

    Are 47cm chain stays longer than normal.  I have Clem like spacing
    between wheel and seat tube?
