More RB-1 Upgrades...Dure Ace Forever!!!

Got around to more upgrades on my Bridgestone RB-1 cause of all the rainy afternoons this week.

Spent LOTS and lots of time taking apart and cleaning up all of these old-school parts...thank goodness I never threw these away!!! Got to take it for a ride yesterday and it was running really good compared to the lower grade Suntour GPX components. And, it felt plenty fast...

Dura Ace FOREVER!!! This rear Dura Ace 7400 derailleur is still super solid with absolutely no play in the parallelogram at all after all these years (and a couple of crashes - one I remember on a right hairpin coming down Tantalus).

Companion front derailleur still shifts super fast and direct. (Took off the 9-speed DA I had originally put on.)

The ORIGINAL 6-speed SIS Dura Ace shifters. Working absolutely flawlessly even now. I still remember when I first upgraded from Suntour friction shifters (with Ultra 6 freewheel) to these "new" indexed shifters. It was cutting edge back then. But still, it only became industry standard when Campy finally got on board several years later. Once that happened, friction shifting was gone forever... Although, Shimano still provided a fail safe friction mode with a twist of the D-ring.

Back in the day, I had all the cogs to make straight blocks, wide ratio sets, super low gears, whatever. Of course, a 6-speed Dura Ace 7400 freewheel with champagne colored Dura Ace Uni-glide cogs.

Weight savings compared to Suntour GPX.

Crankset: 690-595=95g
BB: 300-190=110g
Bolts: 40-0=40g
Front D: 105-100=5g
Rear D: 225-200=25g
Freewheel w/ cogs: 25g???
DT shifter R: 50-45=5g
DT shifter L:5g???
TOTAL SAVED: 310???
