I've enjoyed the "Aero Bars" thread. I wonder if we can do a parallel thread on The Aero Stoker? Looking at John Cobbs wind tunnel video:
it's pretty obvious that his smoke trail would be sucked right into the stoker's chest. I know I notice small changes in my stoker's position. The parameters for the captain's aero position are fairly well known. It seems to me that an aero position for the stoker is much trickier, given the varying sizes of captain and stoker and the mostly invariable length of the stoker compartment. I've also seen more variation in stoker position on road tandems than I've seen in captain's. I'm curious about the drivers there.
For instance, I notice in Merlin's photo in the Aero Bar thread that his stoker's cowhorns seem to point down a hair, rather than up as one usually sees. It'd be nice to see photos of standard aero stoker positions, with and without stoker mounted, and how their contact points interact with the equipment. There are zillions of photos of single riders to look at and learn from, but not so for stokers. I'm most interested in comfortable, sustainable stoker positions that will contribute to increasing overall tandem averages over a long ride.
Funny how the riders in Cobb's video seem to refuse to position their helmets correctly. I wonder what that's about. I also wonder about an aero stoker helmet.
Here's us in aero position:
Stoker can't hold this position forever - her arms get tired. I'm thinking about tilting her bars down a little so she can rest more of her wrist on the bar. The bar end keeps her hands from sliding forward, so that's what she's braced against. OTOH, maybe her bar should be a little lower so she doesn't have so much elbow bend. I don't really want to go to a drop bar because that puts more forearm in the wind and she likes the cowhorns anyway. This photo:
shows a little less back angle on the stoker than on the captain, though our arm angles are similar, so maybe her bar should be lower - or maybe just angled down a little.
