thanks everybody. Thanks for reminding me about the rims. My current bike is a mountain bike(a slug), the next one I'm looking for is a road bike. The up to 40 pounds grocery load is carried mostly on me(backpack). My rack is one of thoses attached to the seatpost. I wanted a regular rack but it seems like the disc brakes were in the way. When I get my next bike the Haro will be a beater(most rainy days and shopping). My next bike...I more concerned about making it go as fast as I'm able, only able to handle a rack and fenders(it's going to be a commuter after all. thank again.
