Thanks Owen. I think it's on the right track and now I just need time to get the fenders installed, swap pedals, and do some fine tuning. I'm not too worried about the Cerf tires on the tandem. We're already running GB Hetres on the Bilenky and the Norman Rapide has GB Cypres and they don't seem any more flat prone than other tires. I think the delicate nature of Grand Bois tires is a bit exaggerated.

The pictures were taken at the usual spot - the MARC train station just a short way from our home.
