We are unable to offer factory upgrades/changes on our bikes. They are sold as advertised to our dealers without option to change components or frame colors. Any desired upgrades would have to be discussed at the shop level.
What we DO offer is a crank length swap program for S-Works bikes that have our Specialized FACT Carbon cranks. If the stock cranks are not the size that you need, then talk to your dealer about our carbon crank swap program.
