Is there such a thing as a tandem specific handlebar? Seems to me that I do "load" the handlebars a lot more on the tandem than on my single. Just keeping the bike upright when we're at a traffic light requires a heavier hand, since we've decided to keep the stoker clipped-in (so I'm statically balancing her weight when stopped). I have also noticed that tandeming is definitely a bigger upper body workout than riding a single.
