So you're saying $300 for a Platinum OX track frame with the Kilo TT geometry? TIG-welded, I presume? Will this be sold as a stand-alone? Threaded or threadless.
I don't know if it's worth the investment, but I think that shipping it with Sugino 75 cranks would probably be popular. I don't really believe that most riders actually NEED 75s, but I think the kind of person who wants a high-end track frameset is also the type who drops $160+ on top-shelf cranks.
Also, no matter which steel you use, put the sticker on there. Bike nerds love showing off stuff like that.
