I just bought a Salsa Campeón, Las Cruces, or Chili Con Crosso frameset and I think the seat tube is dented?
Don’t panic, we intentionally put a relief on the drive side of the seat tube just above the Salsa scandium decal. With our wide 35mm seat tube (making the bottom bracket 20% stiffer laterally) this relief allows the front derailleur enough clearance to move into the small ring if you’re running a triple chainring crankset. The relief is made in our scandium tube before heat-treating and has no negative effect on the strength or integrity of the frame.
