I understand this (with I'm guessing something like 13-24 cogs in back) is not supposed to be able to work correctly with DA 7400. Curious if anyone here knows whether this is true...in other words, I'm curious if anyone's put a 39 small chainring on their otherwise original DA 7400 group and if so how has it worked out.

I thought DA7400 came with a 53/39 option? No?

I have a bike with 8 speed DA(7402 rear derailleur), 53-39 & 13-26 cassette. It shifts fine through all gears.

The crankset is a 7410(last version of 7400 crank)

i run that crank on my Pinarello with DA setup. With no issues, i would prefer to 42 but that's what the crank came with. It's not too hilly in toronto.

I'd swap you my 42t for your 39t, if you weren't a million miles away. I got these cranks real cheap, because the arms were pretty beat up, but they sanded out really well. Gotta love those engraved DA logos, they won't easily get worn off, LOL. Oh, I have the stock (I believe) Super Glide 52t 42t chainrings, but haven't really tried TOO hard, to find a 39t, so I can't really comment about compatibility. (?)

Yes, it works fine. And I even have one with a 28 rear cog, also shifts great.

+1, not an issue. You'ree exceeding neither the max cog size nor the chain wrap capacitiy. I've run a near identical set-up (52T vs. 53T) on mine, without issue.

I have the exact same setup and gearing on one of my bikes, and the 39-26 combo gives 40 gear inches, perfect for my needs.

+1. No problem with the 39-26, except I've got a Sante freewheel and a C-Record crankset.
