  1. Data limitation

    No geometry is recorded for 2007 Co-Motion Periscope Scout 700 and 2010 Co-Motion Periscope Scout 700.

  2. Gearing

    2010 Co-Motion Periscope Scout 700 has a 6% lower climbing ratio than 2007 Co-Motion Periscope Scout 700.

How it works

Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
