Ok....more musing on all of this. Spring needs to get here so I can stop being stuck in the house obsessing over bike builds, LOL!
Here's the majority of the Dura Ace stuff on hand. Ranges from rider quality to near mint but not too worried about the looks.
What's there to choose from:
FC-7400 172.5mm 53/39 at 21 ozs
FC-7402 170mm 53/39 at 22 ozs
FC-7402 170mm 53/42 at 22 ozs
FD-7400 at 2 ozs
FD-7403 at 3 ozs
RD-7400 at 7 ozs
RD-7401 at 7 ozs
RD-7402 at 7 ozs
BR-7400 at 11 ozs
BR-7402 at 12 ozs
BR-7403 at 14 ozs
BB-7400 at 9 ozs
BB UN55 at 11 ozs
Shimano 8s chain 12 ozs
Sram 8s chain 11 ozs
ST-7400 at 18 ozs
I'll pair whatever combination I pick with a new SRAM PG850 12-26 cassette.
Now for the part I'm never 100% sure of with 8 speed Dura Ace, all is compatible above, correct? If I pick the lightest of each part there's a savings of 8 ozs total. That really matters when you weigh as much as I do, LOL!
