Here is my all purpose bike. 2000 Specialized M2 Pro Stumpjumper. Originally owned by a serious XC rider who was two inches shorter than me. So I had to raise the stem (adjustable) and used a trekking bar. I have two sets of wheels: one with mountain tires and the other (pictured) with Specialized Fatboy 26x1.25 slicks. It is an incredibly light and fast bike. I actually added a little weight to it because I replaced the flat carbon handlebar with the trekking bar and added a rear seatstay Greenfield kickstand.

I will add a seatpost rear rack. The one I have won't fir the 30.9 mm seatpost so I have one on order.

In the summer, I use this mostly to go to the tennis courts. A couple bottles of water on the bike and a backpack for the rackets, balls, etc. I actually used tennis grips to tape the handlebar.
