Yes--all Lefty hubs are interchangeable. The only "compatability" issues stems from the former use of 4-bolt brake mounting points (you had to use 4 bolt brake rotors on the older hubs).I have a 2001 Jekyll with Lefty ELO. I just bought a 2010 Lefty Speed w/DLR. Is my 2001 Hub going to work? Is there anything else I will need to put this on my 2001 Jekyll?
Also looking to sell my ELO if anyone is interested.
