Hi there I recently put a set of Mavic Crossmax ceramic coated wheels on the IBIS , using Fibrax ceramic pads and Suntour XC Pro SE Brakes , I thought this would be the daddy, but so far nothing but disappointment , the brakes are just pants, The brakes and pads seem to be fine adjustment wise,I thought it was from me not using cantis for quite a while so I was expecting some loss in power compared to discs but there seems to be no stopping power really at all, recently tried some LX Cantis on Dr S Singlespeed and they were awesome compared to my setup,,, Is there something I am missing or what ? any help would be appreciated ..
