at A pal got it from Si Bike Setup:
Falcon Tange Cro-Mo 23 inch frame ca 1979(yeah). Mostly with DA 7400 retro-fitted components (downtube shifters); Campagnolo Super Record Road pedals with toe clips and Binda straps; Cinelli bar and stem; Mavic MA 40 clinchers 36 hole bound to Campagnolo Super Record small flange hubs with 3 cross DT db spokes (training rims); Mavic CX 18 32 hole tubular rims bound to Dura Ace 7400 bubs with DT db spokes. Continental Competition tubs. Summary:
Not really a review. Hoping to save some folks who buy the Dura Ace BR 7900 calipers some grief. If you've bought these and are fitting them to a bike yourself, BEWARE of losing the small plastic (teflon?)sleeves that are loose inside the barrel adjuster. Strengths:
Look well made. Stealth appearance grows on you. Looks better in real life than in the images on the web. Still gotta use it. Weaknesses:
BEWARE of losing the small plastic (teflon?)sleeves that are loose inside the barrel adjuster. There is no mention of these in the Shimano literature 'Technical Service Instructions SI-8FNOA-001', nor in 'Technical Service Instructions SI-8FNOA-002'. The brake set will work without these, but may not be as smooth; or continual rubbing of the inner cable, might 'eat'/ abrade the inner surface of the barrel. If reinstalling a 'popped out sleeve', note it has a slight collar that keeps it in place. The sleeve should be replaced with the collar up.
The 'slick low-profile barrel adjusters' could have had the adjuster a bit more aerodynamic - maybe just a plain circular (ahem titanium) knurled adjuster would be better. These are going to be on bikes in Tour time trials and so on. The present adjuster would be better off on a mountain bike.
As for the 'not compatible with' older brifters, I dunno. The reason cited for this is ' the brakes will be too strong'. Go figure. Similar Products Used:
