Well...i've been commuting now (off and on) since May of 07. It's great and i've been improving with time. At my job however, I can't do without my trustworthy MacBookPro 17". No I can't leave it at work, as I use it at home as well. I have been transporting it back and forth roughly 7km each way on my back in a backpack. I have a seatpost rack where I carry my lunchbag and Nalgene Lemon water for the day.
Here is my question. Is there an alternative method of carrying what I am taking to work, that would allow me to eliminate the backpack?
It is a mountain bike that I use for trail riding on the weekends. So, a rack to hold paniers is out of the question. I need some sort of device I can attach and remove quickly from the bike that can hold my lunch, water and laptop.
I know this is a high order to fill, but there is no fault in asking!!!!
I use a Schwinn Rear Seat Post Rack
bike looks like this (without seat post)
