My Hanford rode perfectly. The only mechanical issue was a puncture(slow leak) that happened on the way back from Brest to Carhaix. I was able to pump it up to pressure and ride it to the controle to change the tube there. I remember marveling to myself how the bike just became part of me, as it was never an issue. It was a delight to ride and ascended as well as it descended.
One note was how many bikes participating in PBP did not have fenders and how I appreciated the full fenders during the rainfall and after the rainfall.
