I was fettling my bike last night ready for Verbier and adjusted the geometry to make everything a bit slacker. The Orange web site says it ought to be OK on this setting (a bit dodgy if you go one further or on a 14 inch frame though). Last year when I had it set up like this the back tyre buzzed the seat tube just before bottoming the shock out. Is this a big problem?
It's a 16 inch 2008 frame.
