I'm a commuter that puts on over 5,000 miles a year on my Motobecane Fantom CX between work, church, and training for long rides.
In the last two years I've gone thru two rear rims. First one (original) because of the weight carried in the rear panniers and me - vertical stress fracture at one of the spoke openings. So I had a Velocity rim built last year and in the course of one year I made the rim sidewalls go concave and on the left side seam of the rim develop a crack about an inch long horizontally on either side of the seam. The rim was still true, I'm religious on cleaning the pads and rims every week. That was $200 for that rim.
I just replaced the rim with a second Velocity rim. Now I know Velocity rims are great rims, I just put it thru a lot of use. I've been using both brakes equally but dollars and cents wise got me to thinking of not only using the front brake more often but in 2011 switch the front fork and go to mechanical disc brakes for the front for greater braking power, save some $$$, and keep the rear brakes the same.
Any thoughts of my game plan?
