Hi mate,
The steerer is ahead, although it is easily changable with two allen bolts on the back of the crown. I'm sure you could pick up a threaded one on here without much trouble if needs be. Its aluminium so maybe it could be threaded easily i'm not sure. I can't remember what the steerer length is off the top of my head but I will check for you tonight. Plenty on there though.......... 210mm ish at a rough guess.....
