I've got a Wabi Classic running 44 x 17. Mine's got a flip flop hub that stays on the fixed side unless I'm using it as Paddock transportation. I find riding it as a SS negates all the great road feel it has when fixed. I'm not cool enough to go brakeless, I run front and rear brakes. Love the bike!

The Wabi is based on road bike geometry as opposed to track bike, very comfortable and fast.
