Good looking derailleur. But like most that come in to me, it needs a complete break down and cleaning. If the movement of the body is solid, I would not do anything to the rivets. I think you will like the look of the cleaned up unit. Most of the ones that come to me look like new after a good cleaning. If you need new jockey pulleys I have been buying sealed bearing units from Chaser Tec that work well. Smiles, MH

I believe that modern oval rings are clocked "opposite" of biopace. Biopace is a lower gear when your cranks are at 9 and 3, and a higher gear when your cranks are at 6 and 12, the idea is that your legs gain some momentum through your power stroke to carry over the top of the crank stroke. I found they were more likely to break traction as you have a lower gear when you have your greatest power thus sending a large torque spike to the rear wheel.

Modern oval rings are generally set up so the gear is higher when the cranks are at 3 and 9 which reduces the torque spike of your pedal stroke to the rear wheel and then the gearing is lower when the cranks are at 6 and 12 when you have much less power.

There is a NR with the long cage and the original short cage on a facebook group for $130US but I got this for almost half.
I noticed the outer NR plate in the one photo and it didn't even register with me that it was from the same derailleur (duh!); that would certainly explain the disparity of the pivot pins if it is indeed built from the parts of 2 or more units. I have one or more NR derailleurs for nearly every year they were made, and plenty of SRs so no more buying RDs. I could easily fabricate some long cage plates from some billet stock if I want to run a larger rear sprocket, but it's nice to have the real thing. I wrote 28t because I know I've used the short cage NR unit on a gear of that size. If you can feasibly use it on a 30t sprocket then I would probably not need a long cage if the NR unit can cover that range since I rarely use anything over 30t. I think the long cage plates were going for around $50. I'd say you did well in the purchase, even for a "rebuilt" unit.

This is going on very faint memory, from BITD when it was introduced, but doesn't Biopace have five phases, actually?

Yea, I don't doubt it, they are severely messed up! :-P

Looking at a BP ring I can sort of make out 4 lobes/peaks, but all in all they are fairly close to oval.

If the BP rings do help your knees scarlson, I have some I'll send along to you for the cost of postage.

CL purchase for <$130. A wheel set of Campagnolo Record hubs, Campy 10V block, Ambrosia rims and contental tires.

Slated for the De Rosa Professional. Guess the color scheme is going to be black and red with some polished AL. Thinking about Campagnolo 10V Carbon Ti RD.

They're pretty hard but should work.

Not in the post exactly, but the effect was the same. Yay!

I'd bought these in Gaiole in October, and managed to misplace the bag when unpacking as I got back home. Just found it again.
  • a generic white cap
  • a pair of black hoods for Universal 77 levers
  • a pair of unused-looking but very incomplete MAFAC "RAID" brakes
  • a new bottle cage with handlebar fittings
  • two pairs of hoods for Campagnolo levers
  • a new pair of my favorite gloves

Some goodies which will get scattered among my many projects. Nice Cinelli and Shimano parts from Miguel. A Shimano Tiagra triple crank from Dave.

Thanks to both you two!


Couple of days ago.

About a week ago.

Those brake levers are very pretty!

Does that towel say "French Rust"?
