has anybody had experience with shimano 10mm pitch dura ace stuff. I was at the lbs yesterday and he told me i could have all of his 10mm pitch stuff for $500 bucks. seems like a good deal for 6 chainrings, 10 cogs, and 2 pair of high flange wheels, and a set of cranks. i'm just worried that i'm going to have to start breaking open xerox machines to steal the chains.

the main thing i want to know is if the gears are equivalent to their regular equivalent... becasue they look smaller a 48 tooth chainring was about the size of a 40.

That sounds like great deal IF you have a source for chains. Industrial 3/8" pitch chains are readily available and cheap, but I don't know if they will work with DA 10, although I suspect that they are identical in pitch, if not in width.

The ratios will be the same regardless of the actual diameter. Smaller diameter rings put more strain on the chain, bearings and axles, but that difference is only about 20%. The smaller chain is also weaker. A small diameter 48 tooth ring should work fine, but stick with bigger rings to minimize drive train stress.

DA 10 will save some weight and make a unique looking bike, so go for it if you can get the chains.
