For some reason, known only to them, my early offroad riding buddies rode Spanish bikes, one had both an Ossa and a Bultaco trials, and switched every weekend. The other had a Montessa cross country bike and I must have towed that pig out of the mountains on the end of a rope at least 4 times. Crap, what a pain. That Ossa trials was a cool bike, reliable and strong but very peaky power curve. I have some pics of that bike buried up past its little saddle in high country muskegs. Man, that was a couple of lifetimes ago. We did ride some incredible terrain in the northern Rockies of Alberta and I miss that very much.
