2010 Air 9 as Singlespeed - Options?

[boomvader]

I currently own a 2010 Air 9 setup as a singlespeed with a Q-ring up front and a Roloff tensioner in the rear. I bought it like this and would like to know if this frame has any options for an aftermarket EBB or should I just keep the tensioner and ride...

Thanks in advance! :-)

No options as the frame is meant to accept a 24mm spindle crankset. If the bike was made to accept a bb30 shell, like the newer air 9s then you would be able to use a EBB. Tensioner, "magic gear", or one of those eccentric rear hubs is it for that model of air 9.
