I have Giant ferrago 29er dual suspension [1998?] bike I picked up on the road side with a free sign. Cleaned it and lubed it. I put 10 miles on it the other day, it works 100%. It has a crmo frame and weighs 35 lbs and rides well. I was looking at the front fork it is 1” threaded and the steerer tube is held to the fork with pinch bolts. Would it be feasible to to press the steerer tube out of a 1 1/8 thread-less and install a pressed in spacer to install the 1” steerer tube?
