The latest Mtbr Reader Survey (with 2700 responses) shows that over 10% are planning to buy a 650b bike. 7.5% of that are focused on a full suspension 650b bike. With very few choices in the market right now, Scott is in a good position with this bike to cater to this new appetite.
A good discussion on this bike is available here: http://forums.mtbr.com/650b/2013-scott-27-5-a-799396.html
Check out the geometry on the Genius 700.
Here is a comparison between the told 26er Genius and the two new Genius wheel sizes. The graphic below compares the geometries of the New Genius 700 (green) and 900 (blue). It reveals that the geometries are almost identical in spite of their differing wheel sizes. Because the bottom bracket drops as wheel sizes increases, the BB axle migrates further below the wheel axles for a low slung feel. With the new Genius, riders will therefore enjoy a more ‘in-the-bike’ experience than ever before and reap the rewards of improved handling and stability. The Genius 700 and 900 are the only bikes in the Trailbike segment which offer adjustable geometry. By changing the shock mount chip, BB height increases 6 mm and steepens the head tube angle 0.4°, while handle bar position remains unchanged.
