I have a mechanic at my LBS that states the D/A 10 chain shifts much better that the Campy chain. Has anybody tried a D/A 10 speed chain on their Campy 10 set? Better yet how about a D/A 10 cassette and D/A chain with the Ergo set?

You can use 9sp DA on 10sp Campy according to Lennard Zinn's-from his Velonews column: http://www.velonews.com/tech/report/articles/5233.1.html

Ok so first off, does it fit and does it work, well to be honest it does fit and from the visual inspection it fits even better than the Campy C 10 chain, basically because its a little narrower BUT i'll ride it tomorrow for the first time, so an update will be coming soon on actual riding and shifting performance. To this end i have listed a bit of information below that might interest readers about my findings and observations between the two chains There is now a decent ammount of clearance between the cogs next to whatever one you are on with the Shimano chain, so any rubbing by the link plates is going to be almost non-existent. I had noticed that because i ride the 53x19 a lot in training and climbing, the bigger diameter 21 which is next to the 19 had some little impressions on its side where the link pins had rubbed repeatidly, the 17 on the other side had none, mainly because its a smaller diameter cog, but if any gear is used often enough, it would be safe to say that the Campy chain would mark the side of the cog thats bigger and next to the one you are using often for sure, with the same results. This kind of makes me wonder why Campy chose to make their chain in my opinion a little too wide, while Shimano went to a slightly narrower chain. The next plus for the narrower Shimano chain is that it will shift quicker since theres less side play to take up before a shift, but your derailleur indexing has to be even more spot on, if not you could have a bunch of missed shifts or chain chatter. Since the price of the Shimano is almost half the cost of the regular Campy C 10, and the life of these chains is not much more than 2000 miles at best, it makes it easier to spend almost the same money for two Shimano units against the money for one C10, so cost is very good for the Shimano unit. While i have not had any problems with excessive stretching of my previous Campy C 10 chain, it has started to make an annoying clatter type of noise while pedalling, and i cant get it to shut up no matter what viscosity of oil or home made brewed up lube i use, sure at first once you lube it,it is quiet, but after about 10 miles its noisy again. This only started to appear after about 2500 miles, so we are getting a bit long in the tooth with mileage according to the chain gurus. This now tells me that true to form while the chain still is not stretched severely to be out of spec, it is in fact slowly dying, since i can only assume that the noise is coming from the rollers slopping about as they make the turns through the derailleur pulleys and over the top of the rear cogset, since a visual inspection shows no other major wear to create this noise. Will the Shimano chain live up to the level of the C10 or will it be better,tomorrow morning it gets broken in with some intervals, so lets see what happens.

As promised i would write an update on the D/A chain after testing it out and as i suspected it passed with flying colours. The shifts now are more precise and a lot quicker as well, and there's definately less chain noise too and no clunking when changing from larger to smaller rear cogs. All of these improvements are coming down to one significant thing with the D/A chain, its just that little bit narrower and this helps it work better in all areas. Of interest here is the comments made by testers about how stiff the new D/A crankset is, with raves about no chain rub against the front derailleur while sprinting. Even now with this narrower chain it doesnt even rub an older style Campy C-record Crank with my modified chain plates to work on 10 speed, and a 10 speed Record front derailleur in tow. Think of it this way,if you make the chain narrow enough, the sides of it will never rub anything.
