Wide Rim Weight Reduction Experiment. For Acceleration Improvement. by Brian Miller, citizen scientist. CONCLUSION: Worthwhile. For the environment of paved city street riding, improved deceleration, acceleration, and steering speed are rather beneficial; lighter rim is better. ABSTRACT: An unusually wide bicycle rim is needed for a high performance urban bicycle project. To improve [more…]
I hope these pictures help you figure out this air fork a little better. Thanks for looking.
Which has less mass, steel or air? On most planets, an air bladder is much lighter than a steel spring. There are other performance parameters, but air springs are light. A suspention air fork for a bicycle can often be almost the same weight as a dead rigid steel fork. The other parameters include stiction [more…]
