I have an 08 ML and I am running 170 mm length Race Face Evolve crankset. When I'm riding I feel like I am riding on top of the bike instead of "in" the bike. I've thought of changing to 175 mm cranks but not sure if that small of difference will change the feeling top heavy. Any thoughts? Oh yeah, I love the clearance with the 170 mm since I live in Vegas and deal with all the rocks at Bootleg Canyon, but some of the sharp switchbacks I think twice about since I feel too tall on the bike.
