There is quite a difference in price between the two. The Dura Ace ones have the nickel finish in them and is supposedly more durable than the regular anodized aluminium. What say you and thanks!

Nah...not really a collector build. My bike has Dura Ace 7700 all around and I was trying to keep it that way. It not, no real biggie. The Ultegra 6500 chainrings for a pair is around $75-$80, while the Dura Ace 7700's for the pair is roughly $140 - $155. Any other aftermarket rings you can recommend?

Word of caution here. The TA rings are not going to match the Shimano shifting performance. Shimano's ramping and pinning and the resulting shifting is something no aftermarket manufacturer has been able to match.

Older designs (Ie NOS) wont do that either .. better to get a current chainring , just not the High end ,

since they dont even use a flat 5 arm crank anymore ..

When you mean "current chainring", what are you referring to? I have DA 7700 cranks.

Ultegra chainrings ARE the "good stuff". The cost difference for the Dura Ace rings is not worth it and the nickel plating is more for appearance than wear resistance. I have a pair of 6500-series Ultegra chainrings with over 30,000 miles on them and they are still fully functional and shift well. How much better do you expect the Dura Ace rings to be?

I must disagree with this statement! I'm as picky as anyone, and my 10 year old TA chainrings on my 7800 bike (with TA crank) still shift beautifully. The big ring is nicely ramped and pinned. Is it as good as a new 9000 set up? It better not be for the money they charge for that stuff (!) but TA rings make beautiful music with KMC chains. I recommend them without reservation. They are beautiful and wear extremely well.

Not much really. One the main reasons I wanted to get the Dura Ace rings is because the rest of the bike is equipped with Dura Ace. I just need to get over it and not worry about I guess. :-)

Recommend these over Ultegras? Calling Peter about his opinion on Mon.

If you go with the Ultegra chainrings and someone notices and disparages your choice because you didn't maintain the "purity" of your group, be sure to let me know.

HA! I'm not really worried about it. I know the Ultegra is good stuff. The rings are about $75-$80 cheaper and I really just want to finish this build so I can get out on the roads.

Not necessarily OVER them, but I like having beautiful parts on my bikes, and the Hegoa rings are gorgeous and light. They work nice too.....

So did you actually wear out your current DA7700 rings? If so I'd change your chain/cassette more frequently. Or you just ride a LOT. At the cost of those NOS DA7700 rings I'd just get a lightly used DA7800 crank and call it a day. Hollowtech II

If you want really durable rings go with steel. There's a reason cassettes are made from steel rather than aluminum (the reason is hardness.)

Well...two things. The inner ring is a bit worn. Plus my shirt caught a tooth on the upper ring of my outer ring (disassembled for rebuild) and consequently went crashing to the garage floor breaking 4-5 teeth.

Will the DA 7800 cranks fit my BB 7700?

No. You will need an external bearing bb for the 7800.
