I was thinking about switching my stem over to have a more upright position, it's flat at the moment, but thought it was already fairly upright. Might be worth a try though, but unfortunately need to change the cables since the outers are too short to allow the move.
Gearing, a very good point. I did have a compact with lowest gear of 34x27 but to be honest, I wasn't exactly "spinning" on the climbs even then...perhaps a triple is worth considering for these climbs? What kind of weight disadvantage are triples?
Mike, I've heard of lot of these kinds of stories, one friend specifically said that their literature made it sound scientific but it was so far from this as to be more a case of trial and error and the advised position actually ended up causing more problems. But then I've also spoken to people who have said it was fabulous and it has helped them generate more power and comfort, as opposed to worrying about aerodynamics...
Matt, no it is only when climbing in the saddle, climbing out of the saddle actually helps alleviate it, but unfortunately I'm usually that tired that getting out of the saddle can only last a couple of seconds! I climbed the Penbarras in North Wales yesterday which I believe has a bit at 30% and never got out of the saddle - maybe this is technique that is putting too much pressure on my back? I very rarely get out of the saddle - I used to a lot when I was road racing - but for some reason I don't anymore - no idea why!
I don't suffer with back pains under any other circumstances, so I too pray I don't have anything more serious. More a case of being fat, inflexible, lacking gears and generally unfit (never thought I'd hope to be that
)
