Aha Rigid Carbon....... That's a great choice!! I recently added a carbon fork(Nuke proof from CRC) on my Litespeed hardtail, I didn't want to get another 80mm suspension fork. You save a lot on weight, the climbing is awesome, and off road riding isn't all that bad...? The Carbon soaks up a lot of vibration, however, it's not meant for fast technical decending, where handling comes into play...!! It will take anything you throw at it, the question is.......WILL YOU TAKE IT??? All in all a great upgrade, especially if you comute a lot!! I RECOMEND IT!! ENJOY!!
