The prompt
make it a bsa bottom bracket, ES34 headseat, 29.2mm seatpost, i want the rear seat stays to intersect the seatpost a little bit lower and offset them, make the top be an inch lower and the second be just below that and have them a little more offset to their respective sides. I want the tubes to be much thinner, mainly on the back half of the bike. Make sure the downtube is fully joint with the headtube, it might need to be a slightly steeper angle up from the bottom bracket. I also want you to add a brushed and anodized black finish on the bike
