Howdy from Duluth!
If you've been riding TWOgether 7 years we are sure stoker knows your riding style/capabilities.
Brake control on rear of tandem, operated by stoker would be more ideal. If you'd go for full drop bars for the stoker, barcon would be mounted in drop position where it would not interfere with pilot's leg. Would elminate pilot fumbling with extra lever on his front bar and would also be a shorter cabe run.
A set of dummy stoker levers would give stoker more hand positions, including the drops, as opposed to cowhorns; and drops would be a bit more aero.
Co-Mo folks would be glad to make the change; however, your tandem/your decision!
Pedal on TWOgether!
