Hello, I am new to cycling. I'm looking for a speedy commuter hybrid type bike. I want it to be sporty but also be able to handle packed dirt and crushed gravel trails. I will mainly be on the road however. I have narrowed it down to these two bikes but I was also looking at a schwinn volare and a schwinn tourist. I would probably have to put a slightly wider tire on one of those because the tourist comes with a 28 mm. So any advice on these or others would be much appreciated. Cost is a factor as well. Trying to stay around 350-400. If the pdx is that much better I might be willing to save up the extra green and get it. I would also like to use this as a fitness bike for longer rides.
