Destructive testing in some way could be fun. A cheaper one would be to test the effect of handlebar height on speed (aerodynamics). Find a big hill to coast down multiple times with the handlebar at different heights. Most cycle-computers have a max speed reading. To be consistent, put the hands in the same place in each test - I'm thinking resting on the hoods with the elbows bent in a normal, relaxed way, or on the hooks in a full aero tuck, or, heck, try both. Try also to conduct all tests at consistent air temperatures and pavement temperatures and no wind conditions and keep tire pressure consistent. Plot max speed vs handlebar height (stem protrusion or height from the ground?).
Then plot max speed vs handlebar height. Maybe max speed squared vs height. Try to find a relation that gives a straight line on the graph. The slope of that line would be a useful coefficient relating stem height to speed - i.e. for every cm higher the stem is raised, you lose x kph or kph. MS Excel is common software that does curve fitting and will give you a slope and intercept of your line. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
