I followed it and the link to Peter White's page on fit. Some or most of it felt intuitive to me. The notion that a racerly position would have the rider forward and the hips and back sliding forward and in a touring setup where comfort is more the aim rather than power (here's where I depart from Peter White in regards to power, its wind resistance) the bars are raised and brought back thus the saddle needs to be brought back. Makes sense to me. I think this can be confusing. I get where a Dutch bike that's super slack would have a noticeable power loss but that's at the extreme! In my case with the 9cm stem I feel cramped. I found myself purposely sliding back on the saddle. One reason I like the Albatross bars are that they afford me numerous hand and back positions. In the hooks I'm in a more aero position but not so aggressive to fatigue my back and at the opposite in the grips I'm upright with little to no stress on my neck and back. I have a 10cm stem on the way and that might be the sweet spot I'm looking for? Peter White and probably lot's of others subscribe to setting the saddle first then the stem. It seems I'm going about it backwards. Most likely I'll have a seatpost and stem or two to sell. > > The issue with moving too far back is that your knee will be behind the > pedal spindle and you may end of with an overuse injury somewhere in your > legs.
