Keith: You might want to look up "Nomad's Trails" on youtube. It's a couple from Finland who set out to around the world & start by crossing Europe, then turning down the west coast of Africa, before having to stop due to the virus restrictions. They had enough troubles with their conventional gear systems to look into alternatives. They got new Tout Terrain touring bikes, one equipped with the Pinion system & the other Rohloff, both with belt drives. In February, they set off from Helsinki to go to the Arctic Circle. At last report, both systems had endured the extreme conditions with no problems. Maintenance was washing off the the belt with hot water to clear the teeth of ice.
