Is going clipless shagging my knees?

Cheers chaps... that's a lot of friendly replies in a very short time! You may have something with saddle height - I actually raised it a tad after fitting the new pedals as the new position felt a little cramped. I guess I'll try lowering it again to see if that helps things. I'm kind of hoping it's just a case of letting things readjust as I'm really enjoying the aliums. Otherwise I guess there's always Ibuprofen injections directly into the patella...

Aliums are fucking awesome
