I'm shopping for my first fixie. The Steamroller entices, but I notice it has 70 mm of bottom bracket drop, which is a lot. I'm probably going to get a larger size, and put 175 mm cranks on it, which makes me wonder about pedals slamming the ground. Has anyone had a problem with pedal to ground clearance on a larger Steamroller? Intended use is commuting and bopping around town. I've heard that pedal slam can be pretty disastrous on a fixie. OTOH, low bottom bracket equates stability and efficiency, so I'm still enticed.
