Bike left outside

[soupman450]

My bike has been left out all winter and summer, for a whole year. I want to do some work on it and maybe then take it into a shop for a final adjustment. where should I start. what steps should I take and what to look for. My dad owned his own bicycle shop and so I have some knowledge but am not sure where to start.

Start by cleaning the whole bike and getting rid of rust. Make sure there is no water in the seat tube or bottom bracket.

Than you can service the wheel bearings, the head, and bottom bracket. Clean and lubricate all moving parts and cables.
