Where to find the right stem?

I have a problem with my new bike. It is a quintana roo caliente. I ordered it online, the sales representative took my high and inseam measurements from me. The bike is designed to fit me, but my body isn’t normal. I have long legs and short arms and torso. Because my arms are so short, the bike doesn’t fit. When in the aero bars, my arms are bent at about a 115 degree angle and I know that 90-100 is ideal. I moved the seat all the way forward and it still didn’t cut it. The bike feels great if I sit with my tailbone all the way at the end of the seat, or sit normally and have my hands pulled in closer to the middle of the aero bars. But this is not the correct way to ride and would take away from being aerodynamic. Plus if I sat with my tail bone at the end of the seat it would be terribly uncomfortable. Is there a chance I can order a really small stem? I don’t know exactly which points the measurments are made on a stem, if I know that I can tell you the size of this one. I feel like I would have to get a stem about 5-6 cm shorter than this one. If only I could move the aero bars back grrr

Thanks for the help.

Unlikely you’ll find a stem that much shorter… not knowing your current size, an average length would be 10-12cm, and they don’t get much shorter than about 7cm. Too short and it’ll start to affect your handling as well. What type of aero bars do you have? Some allow you to position the pads much further back behind the base bars than others, might be a simpler fix.

Not joking, but use google or look on ebay & use the search function. If you google 60mm road stem, a bunch will show up.
