So here's the finished product. Hopefully no headbadge pictures snuck in
The LBS guys had to flip the bracket then use a set of P clamps on the seatstays with 2 bolt points, one to keep the clamps shut and one to connect them to the arms of the rack. Looks and feels solid, so I'm happy!
Its a weird relationship that I have with these guys. They're the only LBS within 10 mins of my town (driving distance) and they are in the same town as my work so its easy to jump over after school gets out. However, while the guys are super friendly and helpful it is a bit overpriced and the guys always seem like theyre helping me because they have to, not because they want to. That last part is more feeling than anything, but that being said, I love supporting them as a local business and when they do stuff like this to help me out.
