>>1371993Multiple positions to reduce fatigue from riding all day, narrower drops than bmx/risers can easier slip through tite gapz between cars, and gottagofast when not hauling anything. My build is a little weird but it works well for my niche. I also want to get into track cycling so this build helps me train for that venture.
All cyclist, not just couriers, do things that don't make sense because each bike is built around a person and purpose. Each of us are different with different riding styles and purposes leading to radically different bikes. Compare every bike in this thread for example.
