It was sad news that we heard Sheldon Brown had passed away on Feb 3rd of this year. For anyone who has even casually searched the internet for technical information on bicycle systems, from seemingly obvious compatibility questions that no one seems to answer (like "can you use an 8 speed shifter with a 7 speed freewheel") to obscure details on internally geared hubs, Sheldon Brown's website would turn up like a resource beacon in a World Wide Web that is increasingly dominated by marketing and commercialism.
