Hello,

I've got a 52 cm Cannondale Six13 which has a 53cm top tube and a barely sloped top tube with a 13cm head tube. It's also got a 74 degree seat tube angle. I personally am 5'7" tall with a 79cm inseam, and when using the "divide total height by inseam" measurement, (174 / 79) I get 2.2. This tells me I have short legs and a longer torso I guess?

I've always felt like my top tube is long enough with a 110 or 120 stem, but when setting my seat to the correct height my seatpost doesn't have much raise and so my saddle to bar drop, even with all the spacers taken out and stem flipped, is just 5 cm. I'm wondering if there are any frame manufacturers y'all can recommend that have a geometry that might give me more drop but a longer tube. Hopefully someone else has similar dimensions or a similar situation and can provide some advice. I'm pretty good at fitting myself to bikes, but I admit overall geometry is still somewhat tricky for me to figure out. I guess I need a longer top tube, but a shorter head tube to get what I need?

Thanks in advance!
