In the four years I have owned my 2013 MY Salsa Colossal, everything except for the frame and fork has been changed/updated. Oh, the seat collar and the brake calipers are still stock 😉
My original intent was a one-bike quiver, sadly it didn’t fulfill that. If I had any meaningful criticism of the original Colossal, it would be the wheels/tire clearance. The original Sun Attack wheels were exceptionally mediocre, and my optimism that I could stuff a 32mm tire in there was misplaced due to the tight Enve fork. Both of these criticisms were corrected in the 2nd Generation of the Salsa Colossal. Like many bikes, and in particular the Colossal, a nice pair of modern tubeless road disc wheels, such as the Velocity Aileron wheels I have upgraded to, really bring the bike alive. For a rider of my weight (102 kg/230 lbs), tubeless is an attractive option to pinch flats on a bike that can only take a 28mm tire.
That said, it has long been a bike I love to ride, and I think that shows in my commitment to evolving this bike as I discover more.
The latest iteration benefits from Salsa’s excellent Cowbell 2 handlebars, Thompson stem, SRAM Rival 22 groupset, Wickwerks chain rings, Speedplay Pave pedals, a Brooks C13 saddle, and a Specialized CG-R carbon seat post.
