Matt at All American Bikes in Damascus has nursed my Serrotta for 8 years. For this trip I have had a new cassette added in the rear to increase my climbing power on those mountains out west. I hope this works!
Susan, The day before our CC trip in 2008 we had an optional ride on Vashon Island - near Seattle. Vashon Is. (nicknamed by one of our riders as "Devil's Island") has some very steep hills and several riders changed had their cassettes and/or chain ring changed after this ride. There is a calculation of "gear inches" which is the number of sprockets on the (inner) front chain ring divided by the number on the (outermost) ring of the rear cassette times the diameter of your wheel in inches (probably 27). This number should be 25 or lower in order to make climbing easier. The number for the bike I used is 19, and the number I calculated for your bike Friday was 17.
I have been cycling for a cause for over 14 years and this year in 2013 I am cycling for Parkinson's. In 2010 I cycled from Seattle to Niagara Falls, Canada, over 3000 miles. This year I completed my dream and cycled to Boston from Minneapolis and added 1600 miles to this cross country adventure. Next year, I hope to cycle again for Parkinson's across Canada.
Susan,
