 Had to post this big enough for everyone to see the all-important "Brev. Campagnolo" stamp on the chainring. That's the bit that costs a lot.  The freewheel was so clean I could look down while riding and see the sun shining on the freewheel body between the cogs.  For those who haven't seen the world's first indexed derailleur. The indexing mechanism is housed in the derailleur, not the shifters; an idea they jettisoned soon after. Apparently it was only intended as a layman's technology, as the Peloton frowned on technological innovations of this kind (as they had on multi-speed derailleurs only a few decades before; now of course they have moved into the Electric Age with Shimano's Di2 and Campag's Whatever They Call Their Attempt To Do Electric Shifting). There are some funny stories about Pros rolling their eyes when hearing early adopters in races making the "click, click, click" of the index shift. Not with this baby though. She's 110% steel. And the pushmepullyou twin cables are just something extra special and unncessary. b |

Bendo,
Thanks for that mini history lesson, very interesting- all new to me.

"But how did you get that chain so clean?" I hear you ask. Well I used the Branson 2200, but the bugger shorted when some water got into his innards. Nevertheless, ultrasonic is definitely the way to go.  |

I would be interested in your experiences of ultrasonic cleaning. I have considered it myself but never got around to investing in one. What is the capacity of the late Branson 2200? (Presumably no relations of Richard?)
The new Dura Ace six-speed block on my DA-equipped Viscount Aerospace 400 is still shiny when I look down. Trouble is, it makes me worry that the gap between 4 and 5 is getting bigger and the cogs are somehow working off the freewheel(!) Perhaps because I have for too long used modern Hyper Glide technology; where I have had the retaining ring work loose and the cogs all move towards the derailleur.

I have an ultra sonic for cleaning watch parts and other small metal items. I don't think it's powerful enough though as it takes several runs through.
Bendo, yours looks 'industrial'.

It does take several go's to get a really dirty chain clean. You just change the water each time and replace with fresh. A little bicarb soda and a little detergent is all you need. When the chain is clean it will still need a wipe or a rinse (yeah, it's pretty weird using water to clean steel parts, but you get used to it) as residue of whatever cleaning agent used can build up in the links. But that's not hard to get off. I usually then bake the chain in a warm oven for an hour or so to throroughly dry it out.
The capacity of the one above is pretty large by ultrasonic standard: perhaps 2 - 3 litres? But I think the best results are when you don't overload it and take time to do small loads, e.g. I would probably never do more than 2 chains at a time. b
