I purchased a 1992 Stumpjumper recently and the current fit has me feeling like I'm way too stretched out, practically supporting myself through my arms. The top tube measurement is somewhere between 58-60cm when I normally ride a 56cm road bike, so I'm considering getting a different stem to decrease the reach. Do people here generally say to avoid those Sunlite adjustable quill stems? Amazon has it listed for $10 when a regular Sunlite quill stem is $20, just looking to spend as little as I can on the bike.
