If its like the racks that my town (Fort Collins, CO) uses, I think you'll be fine. I ride a bike with steel fenders and while it doesn't have a front rack I don't think that matters. The rack uses a U-shaped (more like a J, really) bar that is spring loaded and fits over the wheel. The bar actually clips on just in front of the front fender, on the tire. I could put it over the fender if I wanted to, but I think its better to have it on the tire anyway (as it fits pretty tight and prevents the wheel from rolling at all). So anyway, I think you'll be fine. For me the hardest part is getting the bike on and off when the bus is stopped along the side of the street. First bike (often mine) goes against the front of the bus, the 3rd one goes out in front. Sometimes I'm first off and it can be a pain in the ass to get your bike out of the rear or middle spot if the rack is full.
