And yes it does have disc tabs, and I used an Avid Mech until recently. I prefer the Dual Pivot caliper though actually as it is much lighter and gives better braking, but some of this is because I didn't have the disc optimized... and you can't really run tires bigger than 700x28's with DP caliper so you may be better with disc over cantis or mini-v's if you plan to run big rubber.

I had a Cannondale road tandem from the mid to late 1990's before this one, and this frameset is superior in terms of stiffness and handling (tracking straight, through turns, under power, etc). I can't compare to a current Cannondale however. Also, Chuck can set up up with a budget build kit if you ask... so don't think you have to spend $2000 to build it up... I believe in its original configuration I had less than $1000 in it as I bought most items from him from his bargain basement of surplus, but decent stuff. The only thing cheap and heavy we had was the stoker stem, everything else he sold us was mid level stuff for peanuts.

I am pleased with it, and don't plan to upgrade to Co-Motion anymore as I just can't rationalize the cost benefit ratio.
