When a bike hits a shop from the manufacturer how much pre-assembly has been done by the factory?
Tom D is the guy to ask but AFAIK, they usually arrive disassembled.
You getting a little worried about the P3? Your friends on the forum will help you out. First you open the box, then you…
Open box. (writes down open box.) Check!
Road/tri bikes typically arrive as a frame and parts kit. So you need to build the whole thing up.
Lower level bikes/kids bikes will come with most of the bike assembled and all you need to do is slap on the wheels and handlebars and adjust the brakes and derailleurs. The level of assembly does vary from manufacturer.
