I noticed there is virtually no difference in appearance between the front pads, and the rear pads for these bikes, other than the number of vertical grooves in them (Two in the front pads, one in the rear). Are they interchangeable?
The reason I ask is that the rears on 741 were down to metal, and I only had a set of fronts. I put them on, no problem and they stop the bike just fine. But will there be some kind of problem down the road?
