Any question answered...

Cross posted from the training thread - any ideas?

So I'm riding a lot more recently. But have suffered from pain in my knees before (have had physio) and I think I'm on the road to recovery as long days in the saddle aren't hurting my knees at all, or if they do only a little.

But for the life of me I can't spin a high gear without my knees starting to hurt. Is this normal? I can happily spin in the front middle chain ring for ages at around 80-90rpm but if I change to the big ring I find I have to gear down so much I may as well be on the middle ring again.

Will this come with fitness again and is it just my knee getting used to this again?

Do you mean high gear as in hard? If so, perhaps you're not as recovered as you think you are. Take it easy.

Or do you mean spin? Perhaps your pedaling style gets flaky at high rpm. Practise and if pain persists I'd always err on the side of caution and rest ice compress elevate etc..
