So I know comparing these two cranksets may seem strange, but I have a chance on both so I want to know what will be better for my riding. I just do street riding, pretty much every single day in what ever the weather. I want a strong durable crankset, light would be nice but it's not a huge deal. I'm not heavy at all, so that not really a factor. So which crank will really be the best buy? What are the ups and downs on each? I know a lot about the omniums, but I'm looking to learn more on the dura ace for street riding. Thanks

As a matter of fact I've had both 7710s and Omniums on the same frameset (different bikes, but both Pista Concepts. Check my sig). I've also had Sugino 75s on a Pista Concept. I've got Campy C-Record Track cranks on my current aluminum ride which is similar to the PC. So, all in all I have a good frame of reference (pun intended).

I prefer the Dura Ace 7710.

I use an older D-A (7400) set myself but it seems that if your buying these new, get what floats your boat. Unless you race or are a big guy over 250 like myself commuting and skipping a bit now and then, it won't matter.

Your likely in the "what looks pretty" catagory.

Don't sweat it.

And I'll vote D-A out of personal bias. And the fact that AllThingsHip have a crush on Omniums, currently, that would seem to make your daily rider a possible thief magnet...

For the street, I'd just go with which ever is cheaper.

They are both great, and the external BB on the Omniums is durable enough for street use, as is the octalink BB used by the D/A 7710's.

I personally like the moniums, though, and I would probably go with them if I were you and the price was comperable. I'd bet they will be stiffer than the D/A since they have only 1 splined interface, as opposed to the D/A's 2 splined interface. Either way, if you are light, you probably aren't going to notice a difference.

I put my omniums through a lot and like them very much.

thanks guys, can anyone tell me the differences between the DA 7600 and the 7710? Is the 7600 the square taper version? And do both run a 1/8 chainring?

7600 is square taper, 7710 is Octalink (newer version).

edit: fixed link above

Dura Ace track rings are available in both 3/32" and 1/8":

thanks for the links man. Know any good 109 bb for the 7600 that will be less than the sugino 68?

I don't know. I would ask the Mechanic's forum.

so let me get this straight... you're going to put DURA-ACE cranks on your bike to make it *less* of a theifmagnet?

I see way more hipster bikes with dura ace cranks than omniums... in fact i can't even recall seeing a hipster bike with omniums.

john prolly had omniums on his concept before most of the people on this forum even rode a fixie...

there are simply more DA track cranksets around because they're easy to find second hand, not because they're the '#1 choice of hipsters'.

oh, with mine that isn't an issue! ALL scuffed up and only good for commuting. They had a little sliding down the road at some point before I got 'em. Not bad or unusable but no amount of polishing will get these scratches out and for $50 hard to turn them down for utility riding.


hunh...Not what I've seen around these parts.

Hahaha! Not before me.

That was my concept before I sold it to Prolly.

I have no experience with the 7710, but I have the 7600 cranks on my Langster Comp and the Omniums on my Jamis Sonik. I really can't tell a difference in stiffness, although a couple of track racers have raved about the stiffness of the Omniums. I've paired the 7600 with the matching 7610 bb, and it spins extremely smoothly. I guess I kind of prefer the DA cranks for everyday use.

external bb for the lose!

I like Omniums. But I've never tried 7710's.

I can't believe you are even asking Dura Ace! Although I'd favour the square taper model so you can run a well sealed BB.

^ ya im having trouble finding a good BB for the 7600 square tapers. i cant find the 7610 DA BB any where

why?

Sounds like you don't need the performance of either(let's face it, most of us would be more than served by tri-colour 600 road cranks) so here's another vote for whichever is cheaper.

However, two issues to consider: octalink BB's have a reputation for a shorter life because they have smaller bearings due to an oversized spindle. That being said, I've also heard more than my fair share of the wonderful longevity of octalink. Take-away message? Octalink can probably hold up(depending on your weight, strength, and riding conditions) but bearing life is most likely shorter than a square taper of the same quality.

Second issue: I've heard a few accounts of the need to proper torque on truvativ outboard systems. The rational here is that SRAM/truvativ cranks lack the pinch bolt on the NDS crank that shimano systems have. Therefore the torque on the one bolt holding the crank on has be quite close to spec otherwise your bearing life is also liable to be shortened. However, I haven't had any personal experience with this so for all I know, it could just be hearsay.
