. . . the making of XC FS racing machine - STEREO . . .
Based on a quick research and my own experience in different mountain bike frames I laid down STEREO's geometry. Keeping in mind that STEREO is purely a light and fast XC bike, I came up with the following numbers:
Steep head and seat angles are for fast, tight and responsive handling/turning and for better climbing abilities. I've ridden a bike with exactly the same parts but with different frames (the main difference was in head and seat angles) and I definitly liked the frame with steeper angles a lot more. Wheelbase and chain stay length may be changed when the actual suspension design is laid out, but the main triangle should stay as it is... The frame is supposed to have 80-100 mm of front and rear travel and the geometry should consider the sag as well!
