A 26/36 low gear on my tandem??? I could bike the north face of the Eiger... Used to live in the Lauterbrunnen/Wegen area. Loved the climb to Grindelwald when the tourists weren't hammering the road.

This area doesn't quite hav those climbs, I (and my pilots) would hate to lose the 53/11 high gear, but your solution is under consideration for a tandem cyclocross bike.

"A train pass and no car..." Ah, we miss those days!
