I have had the hardest time finding an adapter that fits my 2009 Reba 29er. The brake is a v8/203mm hayes striker trail. The literature says a regular 203mm adapter would work. Unfortunately, the two posts on the Reba are different sizes. It looks like every adapter the literature calls for have two posts that are the same size. I have rigged it with a hope adapter but the brake is not flush. The forward flange is rubbing on the rotor (ie. the forward bolt is too close to the rotor, the back bolt is too far). It is crooked. Anybody know what adapter will work? What is going on??????
