OCP is when you have to buy a certain tire....not for performance, durability, or otherwise...but because it matches your spoke nipples, which just happen to match your bolts, which just happen to match the outlining of the brand logo on your bike.
Oh, and not to mention matches the color of gatorade you are using in your water bottle, which the water bottle was bough to complement your bartape, which matches the color of the cable housings.
And your saddle is picked solely because it's colors match the frame's.
Fred is the guy I try to impersonate on my daily commutes....something fun about hitting 23mph sprints on a mountain bike while wearing jeans and a button up shirt.
