Face to face sale. I think I paid him by venmo.

He seems to want to help though and already contacted the shop he bought it from.

I offered to sell the bike etc back to him for what i paid. I'd be out some money since I bought cranks for it and had some work done at the shop. Shop hadn't mentioned the crack which is a bit off-putting, but I had sent it there for them to swap the RD cable inner.

So I offered to:
1) Sell him back the bike for what i paid
2) Work with him through the warranty process and wait along since it could be a while.

If he goes for option 2, it's possible the frame would be upgraded since all their new frames are carbon. Geometry seems to be the same though. Am I wrong in assuming that I shouldn't have to pay more if he goes for option 2? I just want to make sure my thinking is right. If I did end up with a new frame I'd probably send him some money anyway because it's something I didn't expect, but I also didn't expect to spend almost a grand on a 5 year old bike I can't ride lol.
