I thought about 69-er-ing my Kona Five-0 when its bombers died, measured it all up, knew what kinda travel I needed to keep the jometry, but then hit the Unassailable Wall of Unnecessary Standards (or “UWUS”, pronounced “you wuss”). Being not that into the technical side of bikes I couldn’t find a combination of more than two thirds of the bits (and the bits of the bits) I needed that would fit. 🙁
Oh, the logic of it – the front wheel will have a harder time rolling things than the rear due to being pushed rather than pulled over obstacles, so the front wheel ‘needs’ to roll better.
