Chorus to DA is a better comparison, and DA triple locks you into a funky propreitary middle and granny ring setup.Originally posted by Bruce L

There is nothing proprietary about 130/74 BCD. The DA triple crank uses a 130 BDC for the big and middle rings.The crank arm is machined in such a way that it only works with the DA triple 39 ring, and the granny ring bolts to the middle ring with a non standard BCD. Even tho the DA triple middle ring is a 130 BCD it cannot be used with any other crank,because of the unique way it is machined....The FSA setup is what everyone else uses for a triple except campy uses 135/74 BCD and there are also some 110/74s around.Originally posted by dhk
Can you explain the proprietary setup? I got an FSA triple with my DA 9 sp, 7700 FD, and it works great. It's got the 130 mm BCD on the outer rings, and 74 mm on the inner. Surely FSA didn't have to pay Shimano for rights to these dimensions, or the chainring spacing....did they?
Well, that is alot of hooey.Originally posted by marlon1
It's a shame to cycle with triple. ok not for fun-cyclist. So Dura ace/record triple makes NO SENSE!
By the way, a 52/27 or something is also 1:2 so why do you need the triple????????????? Record has Ti cassettes, the 12/27 titanium won't weight much more then an normal cassette of the record group.
