I think a fully rigid 29er makes a fine commuter. Of all the bikes I've commuted on, this one has been my favorite thus far (for most year round condtions).



I'll occasionally ride my 25mm-tired IGH conversion (nice summer days), but I have to be in the mood for it - the narrow tires and sportier geometry mean that I have to pay alot more attention to the road surface.

I really like rolling along with a good head of steam on my 700x50 Marathon Supremes. It is blissful, and the 700 (actually 28)x50's at 35-40 psi roll just fine - no sense or drag or rolling resistance.

In less than 30 minutes I can have my mild mannered commuter ready to hit the trails. Remove the rack and fenders (5 minutes) slap in the MTB front wheel, and install a MTB tire out back (10 min), then strip the commuting clutter (2 min) and I have a great offroad rig. No, I won't be winning any races on it but it is surprisingly adept on and off road.
