I don't disagree. At the time I typed, his actual cadence hadn't been mentioned. IIRC I stated If he was managing 70, his gears are managable (for him was implied by the one-on-one conversational tone of my post.) If he's doing 30, then he is most certainly in the right to be looking towards gearing.

In fact, given his patellar-fasciatis we now know about, I'm curious about his seat height being one possible cause for both. No power resulting in low cadence & exceeding high pressure on the back of the knee cap causing the patellar-fasciatis. I've never seen how he fits on his bike so we may never know. Also, I don't know if being comfortable at 110 rpm all day is as true as he thinks. I tend to be a spinner & 110 means it's time to shift. A cadence sensor would tell the truth.

Maybe he has only developed fast twitch muscle fibers and has never developed slow twitch due to the implied lifetime of flat land experience. I dunno, it's possible. In any case, my genuine attempt to pass on some nuggets of technique isn't the be-all-end-all of cycling wisdom. I'm not the Wise-man-o'the-mountain. Just a guy trying to offer help. Thanks though for pointing out that more conversation developed while I was AFK.
