Functional bikes. Not Porn not Anti

Not knowing much about the geometrys, whats the differences mainly between your audax ed, that geekhouse tourer and say a geekhouse CX ?

they all look fairly similar to me!

It should come down to their intended uses I'd guess.

An audax is just a slightly more comfy and practical road bike. So they're usually a little more relaxed and have slightly longer chainstays to allow for 'gaurds.

A tourer needs to carry weight, so lower BB, longer wheelbase, more stable with weight stiffer/stronger tubing to reduce flex, etc.

A proper CX bike is just a road bike that's able to go off road (I think), ie still has aggressive geo but with mud and tyre clearance. (if you look at something like the PX road frames compared to the uncle john they've got similar angles. CX bikes seem to often have slightly lower TT's/head tubes especially in smaller sizes.... I'd guess to make getting on/off easier.

But a lot of these bikes seem to get a bit mixed up nowadays. The term "CX" often seems to mean drops and canti bosses.
