The bike fit discussions always amuse me. Over the years I've noticed how my comfort has shifted around. What seemed a good position for a long time became less so.
Today I found that terrain will change the optimal position. Having had the same saddle height for years, I raised it about half a cm and pushed the saddle back 1 cm too. I had set the bike up for rolling hills in England and now that I am doing rides that are long periods of climbing, I noticed a lack of room to exert myself on the upstroke and a lack of room to really stretch my legs on the downstroke. "How odd," I thought to myself. I have always spun easily in this position. Surely I cannot make such a drastic change mid ride? "Fortune favours the brave," I heard in my head. This must be a sign like that which Saint Paul experienced! So I did it.
All is good now. I climbed like a mountain goat this morning. I even overtook some people going up.
