My CL protip is to search for "thought", as in "I bought this super-awesome race bike because I thought I'd be riding it a lot, but guess what after 2 years and 100 miles, it turns out I'm lazy and I make poor decisions when it comes to impulse buys, so now you can have a new bike for less than half price". For example...

The bike is basically brand new ... I thought I would enjoy road biking more but ...

Almost new, used only a few times...thought I would get fit and use my bike more often, but...

Practically brand new Trek 7.1 FX, bought this a few months back but never got the use out of it that i thought i would

thought I was going to road bike but no time, excellent condition, only issue is front tire is flat probably need new tire or I do not know how to inflate it
