What streets are you taking? I used to ride from Park/Adams to SDSU 4xWeek on a roadbike... I blew a few tubes on the potholes, so I know what you are saying - The roads are not very bike-friendly.I ride a bike to work when weather permits (about 8 months per year here). My bike is a 2012 Marin Bolinas Ridge 29er (about $450 new). I love the big, fat tires because the roads here are a mess. Lurch is obviously way beyond my level
