it's really nothing new, if you don't want to wait and if you don't want profiles, just go ahead and buy a pair of KHE flatland cranks, light, rather strong and has the second bolt hole for the 18tooth sprocket. bashring then? or you could always drop tree a mail about some really small tree light sprockets, if you feel that you can trust the system their new sprocket will use (basically no sprocket bolt, just a steel insert that goes against the splines on the spindle. so 2non-drive side crankarms, a Ti spindle and a euro bb, or if you want to mill out your frame, a spanish bb. edit: might as well explain some more two profile race crank-arms 50$ each a premium TI spindle 70$ fit bikes bb with steel cups (not al that is shiit!) 40$ http://www.empirebmx.com/catalog/showdetai...et=catalog.aspx 210$ +sprocket cost equals 110£+sprocket cost instead of 200£ +sprocket cost and all that.
