That sounds like a great set-up! I need to look into those Cane Creek Speedbars and the a disc cover for the rear wheel. I'm gonna go out on a limb and guess that you can't use a disc cover on a wheel that uses disc brakes...

A couple more questions for the group regarding TT on a tandem:
1 is there an aero advantage to removing waterbottle cages (there are four of them)?
2 what about wearing aero booties?
3 is anyone racing with different tires or pressure than you would for everyday riding?

It seems that the areo position of the riders would be one of the first things to address (free), next would be helmets($) and wheels ($$$$$). I guess I'm wondering about the next items to address (I would guess that the benefits become smaller and smaller as you go down the list).

Thanks
