Monday will be one year since I bought my road bike. It has given me over 5K happy miles. Time to change out the chain for the third time which makes it time to swap out the cassette as well. It came with a 50/34 compact crank and 12-25 9 speed cassette. Going down some hills I have spun out and was wishful of an 11 cog. Going up some hills I was wishful for just a few more teeth on the back. I decided to go smaller and bigger at the same time knowing that my in between would have much larger steps, choose an 11-30. Lately in spin class I have been in one cog harder than the instructor/coach was asking for and usually on my cadence counts I was also spinning faster than suggested which pointed me to maybe it being time to kick it up a notch. I was able to secure a 53/39 used crankset complete with bottom bracket for a steal of a price. We will see how this works for me and if it does not I'm not out much plus my teenage son will be able to use it if I do not. At the end of the day my new combination is both faster and slower on each end. We shall see how much big gear I will be able to spin once spring begins. Until then I'll be working harder on the trainer. I'll likely wait until 60° weather to find my top down hill speed.
