I just bought an old Specialized Sequoia as a project bike . . . It's got the shifters in the drop-bar ends, so that's how old it is.
I throught maybe I could bring the bar height up some by raising the stem but I can't get the stem to budge. I've loosened the threaded collar as well as the hex bolt in the top of the stem. No go.
I realize there may be no more height to this stem once I budge it loose, so how do I determine what size it is before I seek a replacement, longer (higher) stem?
