>>2055650I assume you're describing a bike that you are considering buying. The answer is that the bike has probably been in a crash (bontrager front wheel, stock rear wheel), so, you may want to ask the seller about it, in a non confrontational way. You should have it checked for damage of the sort that would happen with a frontal impact. It's not automatically a deal breaker but just go forward with that in mind as a possibility
Some shops are skittish about being asked to inspect a crashed bike and "sign off" that it won't kill you, because it's not their primary area of expertise and they won't want to get sued by the next of kin, so you may want to just learn how to check for it yourself (there are low tech ways to do this, albeit not as perfect as the high tech expensive ways)
Check for play in the headset by applying front brake and weight on the bars, and pushing/pulling fore and aft
Other deformations could cause slippage or grinding in the headset assembly or whatever passes for one these days. Compression ring rubbing? Ring of death? Stuff like that. You'd feel it if it was fresh. If the owner rode it with rubbing, it could have ground off the friction, in which case the ring of death should be visible to the naked eye
You may also hear or feel it from stiff turning, unless the groove has already been ground into the carbon at that point
Forks are pretty resilient even in a crash, but they're also pretty important. Since it's probably a carbon fork, you have to know how to look for damage as you won't see dents or bends
