This past week I have had an opportunity to ride for the first time in 2 weeks. Monday and Wednesday I did 14.26 mile rides, Friday rode 5 miles, and then Saturday and Sunday did 23 miles each day. I have noticed that I have not been averaging what I was doing in December. Is this normal? Also I have been noticing that after the bike kinda gets warmed up there is clicking noise coming out of the crank bearings. It always happens at the same spot, and it doesnt matter what gear Im in. Any suggestions?
