This is the first generation Doug Bradbury Manitou fork. Delivering a whopping 1.25 - 1.5" of travel it was the fork to have back in the early 90s!!!
I love the custom stem Doug made. Must say I'm a bit surprised this one isn't drilled for cable routing, I would have thought he made them all the same. But it seems that the man didn't do something if it didn't need to be done.
There are very few differences between this 1990 frame and my 1989, about the only thing I've been able to spot is that the 90 uses a 27.2 post vs the 26.8 in the 89.
Custom modified Hi-E hub expanded to 115mm front spacing all held together by an shortened rear Ringle Cam-Twist skewer. Imagine how many rear Ringle skewer Doug must have bought for all the bikes he made.
