Hello, Thanks for putting on the pictures. They were taken on our tour of the river Loire using the dedicated cycle way between Angers and Nantes. We have now completed all of the Loire from Sancerre to the sea. It's a great traffic free ride. We have 20 gears, double chainwheel and 10 speed cassette ( Campag- Shimano Deore ) which works very well. The panniers are Orbit Classic, fully waterproof, proved over a few thousand km. Also I would recommend the tyres which are Schwalbe Marathon Plus, only 1 puncture and that from a piece of metal again in 2 years of riding.
David sent us these pictures of there tandem earlier this week but no details regarding the equipment. But as you can see this machine certainly racks up some miles.
