Nice bike that at $350 is toward the high side of the acceptable range IMO. Not outlandish, I’d just rather see it at $300. That said, prices are still wacky in many locations and you could wait a long time for the next deal to come by. If you’re fine with the outlay, I wouldn’t feel guilty about buying this bike and enjoying it.

You may already know this but the size looks to be 56cm to 58cm. You should be fine at 5’11”.
