They make this for cyclocross bikes with a 400mm axle-crown distance, but this would raise the front end and affect the trail, and therefore the handling. ENVE's disc fork has the 370mm axle-crown dimension, but the steerer is tapered (1 1/8 to 1 1/4"). I don't understand why the bike industry has not cottoned on to retrofitting road bikes with a front disc; seems like a profitable no-brainer to me! What would make more sense than running disc front/caliper rear for those still wary of road discs on long, steep descents?

So at this point, it would seem to make sense to have a steel fork custom built (by a reputable US builder) to the proper dimensions and with the standard disc braze-on. I see this as about the only justification for a steel fork these days.
