Reading this thread points out that everyone is different, and there are no hard fast rules when it comes to bike fit and contact points.

People like or dis-like bars wider or narrower then their shoulders. Meaning no rules apply and everyone needs to find what works for them. Same goes with stem length, stem rise, crank arm length, top tube length, etc....

No wonder bike fit and finding the correct size, width, length of the components can get overly complex, expensive and confusing. Or maybe, our bodies are a lot more adaptable then given credit and can accommodate a greater degree of indifference.

My short story.... Started with 42cm bars, came with the bike and work well. Needed replacement drop bars for a SS commuter, 44cm on sale at the LBS. Really like the extra width commuting, but still like the 42cm on the road bike. Have a 42" chest, rather wide shoulders, to help put this in perspective.
