Will these fit Specialized Sirrus 2011 Hybrid Bike
I'm worried that the tube is more oval than round
I use mine on a Fuji Sportif 1.3 road bike with an oval frame/tube. The front guard fits ok. The wires are a bit close to the mudguard, but i modified the guard a bit to make the wires go free. You fasten the front mudguard with rubber bands so the shape of the tube it doesn't matter that much.
