Hey guys, I am really debating buying this bike. I just have a few questions that maybe someone can help me out.

First, I plan on using this bike on dirt trails that are for the most part, pretty smooth. Do you think the 700x25 tires will be ok for this?

I am looking at a 52cm (I am 5'9), does anyone know the crank arm length for that size? (trvth, maybe you can answer this?)

Is the fork aluminum or steel? To the people that have the bike, how does the frame feel for being aluminum?

Well, I guess that is it for now. I see this bike in my garage in the near future, I just want to make sure it is exactly what I'm looking for
