I'm currently running a rigid fork on my DISS. I had a 80mm Duke SL on it but it was like 3 inchs longer from crown to drop outs then my rigid fork so back to the rigid I went. I'm looking for a good 63mm or 80mm fork that is closer to the length of my rigid fork. Any ideas, I was thinking of a 63mm SID but I'm afraid it wouldn't hold up so well. Yea yea, I enjoy the rigid to, but my body tends to disagree with me.
