I have had an unexpected benefit of switching to a drop bar bike. Changing position on the handlebars has always been described to me as reducing hand and arm stress on long rides. I'm not so sure of that, but it certainly makes you change your position on the saddle more and use different sets of leg muscles more. I have gone from every night being awakened by leg cramps 2 or 3 times, to no night-time leg cramps. Why didn't anyone mention that benefit to me before??
