I can recall back in 2005-2006 the S-Bend was considered the fastest extensionrelative to ski bends and everyone switched. Now with more people testing in facilities like wibd tunnels the ski bend and tilted up extensions are nowxall the rage but have the data to back it up.S bends test faster without rider. But put a rider on and all bets are off. Often hands can be below elbows in S bend directing air up into your chest (bad, I see tons of pics of people in this type of riding position).
Personally, I hated the S-bends my bike came with. Tried them for a few months and switched to ski-bends. For me it was a comfort thing as I could stay in aero longer with the ski bends and actually get my body lower with the same stack (turtle shrug).
I always thouught that the big scoop position HAD to be slower. Never went to S bends because they logically made no sense to me. Downhill skiers from the 1960's knew that the narrow elbow high hand position was fastest and these guys have a built in wind tunnel on EVERY descent. Boone Lennon invented the aerobar from DOWNHILL skiing!
How can this position possibly be any good (Jan Ullrich 2003 Tour de France)
When all the downhill skiers always go with this position for the human body when they can:
Ray Browning sets the Ironman New Zealand 1989 course record on a Quintana Roo Superform (first ever tri bike) emulating the above skier position and taking a 20+ minute lead into T2
By 1992, this position was refined and Mark Allan went sub 8:10 in Kona
Why any of you ever used straight bends is beyond me. Not a single downhill skier would ever position their upper body like Jan Ullrich and those guys have a built in wind tunnel on every run.
