Re:
Hmmmmm..... I can answer my own question now.
It's yes AND no!
With a high level of fitness I think it's a great idea.
But, I think with my current non-existent fitness level, and the local terrain, then it's a no. :?
I went out yesterday, managed an hour before I had to turn back. Admittedly I didn't pick the best day or trail, a very soft and rutted trail that just went up and up, and into a howling headwind too. :roll:
The ride back to the car was brilliant though!
I have the motivation, but I just couldn't get any revs up, and I'll quite happily sit grinding away in a low gear.... after all I went out to go on my bike, not to go for a walk!
I have a replacement sliding dropout with a mech hanger for the Black Sheep, and my wheels will take a cassette, so I think I will run it geared for a while until I get a base-level fitness back, then if I feel I want to single speeding, I'll at least have the option. :facepalm:
Seems I need two bikes!
