Last year I did the 204 mile Seattle-to-Portland bike ride on my touring bike. While it was fairly comfortable I felt like I was working a bit harder than the people on "go fast" bikes... especially on hills. Well this year, I have myself a "go fast" bike. A carbon Cannondale Synapse. For the STP, I plan to swap out my saddle on the "go fast" bike for my brooks B-17 on the touring bike. I'm also planning on switching the 23mm tires for 28mm tires.
I think these changes will help with this year's ride. I'd like to hear your thoughts and opinions on whether or not these are wise adjustment.
