I've been asking a bunch of questions here for the past two days and I think I've been asking the wrong ones. I think these questions will help me a lot more than asking which bike to get.
What are bicycle geometries measured in? Most of the numbers don't say if they're using inches, cm, mm, etc.
For example http://www.khsbicycles.com/PDF/Frame_Geometry_AM_DJ.pdf
a lot of those don't say what they're measured in.
Also, for the different type of bikes(downhill, commuter, dj) what kind of general geometry should I be looking for?
For example: For an urban or dirt jumping would I generally want a shorter back end and smaller angles between the seat tube, head tube, and shorter top tube and seat tube lengths?
I understand preference also matters but I just want to get a general idea.
On freestyle bikes, I only really worried about the backends being short and the weight. The rest of the frame seemed pretty similar.
I thought it would be easy picking out a bike but the bigger bikes all look and feel different from each other. I basically want a freestyle/bmx bike with gears and bigger wheels. I think once I figure out how the geometry thing works I can pick out some bikes to try.
If I'm not being clear let me know.
