It's time to change out my Ultegra crankset to an XT treking crankset. This will help my climbing with some lower gears. My Ultegra has 50,39,30 chainrings, compared to 48,36,26 chainrings on the XT. Now all I have to do is scrounge together enough cash to order it. Check out Jez Andrews blog for his Want It Wednesday. http://followingthechainline.blogspot.com/
