Today i rode 61.4 miles from san jose to palo alto and back. The weather was 52F sunny with light winds. The squealing like siren noise that was palgueing for over a 1,000 miles was solved by put some light oil in the rear hub body, go figure and i though the bottom bracket was at fault. I rotated the tires front and back so imcan get more mileage out of them. The chain is already worn out, i lube it every 500 miles. I will wait to replace it till it breaks or 3,000 miles which ever comes first, same with the tires. I also swapped out my romin evo saddle for my Prologo Kappa saddle.
