I added a new front rack to my commuter- from Nashbar for $12.- a very good deal and I just added a nice black basket that I can throw on in seconds and take off quickly.
Had to move out of my office for the summer months due to construction and loaded the rear milk crate to it's limit and then filled the front basket. A total of about 40 lbs of stuff front and rear and then rode home- 10 miles +. Then rode back for another gig downtown tonight. So managed to get in 40 miles of commuting. Hit the grocery store on the way home and loaded up that front basket and the rear crate again! I'm loving it. My commuter is now Uttila The Bike!
