Convert MTB Tandem to Drops?
Have a Tsunami Mountain Tandem that we built up from a Cannondale. Has BB7 disk brakes and the whole kit and caboodle. I want to put on drops and campy ergo levers for more hand positions for longer rides. Drivetrain is a Shimano XT 9 speed. I know there is a trick or a shiftmate to sort out the shifting. Only question now is going from flatbar to road brake leves is a differnt pull. Would a pair of travel agents or rollamajigs allow me to run road levers with mountain brake calipers?

The new Cannondale Road Tandem 2 comes with Avid BB7 disks, Ultegra brifters, and drop bars ... works great.

Don't bother with the travel agents and disc brakes. The cost of doing it properly is easily less than the price of bandages if you cut corners.
For a few dollars more, buy the proper BB7 road calipers which will work with your new levers. The road calipers look identical, but have a different cam / actuator mechanism inside. You could buy the swap over parts from SRAM and convert them to BB7r, but why when calipers are priced reasonable.
Also, you will need to / should buy the Avid inline cable adjusters. Yes, you can live without these, it just requires a more precise cable length from the start.
Check this link for more details, go to page 13, look close at items 2, 4 and at the bottom of the list NS (not shown) is the adjuster.

If you do decide to convert what you have, be certain that you are ordering for the proper vintage caliper. Look close and you will see two series are shown, early up to 2007 and current.
Hope it helped a little.
