A friend just told me that if i wanted to add disc brakes to my stumpjumper FSR that i would need new rims/hubs. I told him my hubs are disc ready. There are bolt holes for disc brakes already on thses hubs, but when i told him that he said that doesn't matter, and that according to supergo there are no discs that will work with the stock rims/hubs for some other reason.
This makes no sense to me. If the hubs are already tapped for discs, the manufacturer must have done it for a reason. It seems like total lunacy that they would tap screw holes for a disc if there is no disc that will fit it !!!
So can someone explain this to me, and also recomend a cheap set of hydraulic discs if there is one that'll fit?
