BB recommendation for Dura-Ace Crankset(9 posts)

BB recommendation for Dura-Ace Cranksetgrettm
Apr 15, 2003 5:32 AM
I would like to get rid of my Coda crank set on my R600. Couple of questions: Which BB do you recommend for a Dura-Ace Crankset? I hear the Dura-Ace BB is a pain in the rear to install and I have hear numerous other complaints about longevity. Will an Ultegra BB work work with the Dura-Ace crankset? Also, I can't tell how many teeth my Coda chainrings have (I don't see them printed). Besides counting them, do you know how I can find this out?

installation is not really out of the ordinary. tighten the moveable cup until there is no play in the spindle. at least, that's what I did.
an Ultegra or even 105 BB will also work.

Even if it means using your fingers and toes several times.Sometimes the markings aren't right either. Just found a '42' sugino ring that looked bigger. After counting about 10 times I had to go with it really being a 44.

I am a product of American education but I will give the counting thing a try.

Hey, thanks for the BB advice people.

Same bearing set-up as regular D/A but without all of the BS of installation and maintenance probs. It's a completely sealed, cartridge set-up.

I remember a post a while back (probably 9-12 months ago) in which this came up. It was said that the track bottom bracket did have the same bearings, but was not sealed well at all. The post said that it was meant for the clean conditions of track racing and would not work well out on the open road. To much grime and grit would quickly ruin it if it was ridden out in the elements.

I may be wrong, or maybe they have changed, but I remember that no one disputed it. And, if the track bottom bracket offered all the advantages and none of the disadvantages of the regular D/A, why wouldn't everyone use one?

considering it's all I'll sell to people who get D/A and I have personally been rocking them for about three years. It's a cartridge and has been that way for about four years. If you have been reading this site for the past 4 weeks, this thread has been on once a week at least! Everyone doesn't ride them because, A)they probably don't know about them, or B) aren't introduced to them by the folks they buy from, be it mailorder, internet or LBS, or C) they aren't offered by many retailers as parts of groups.
Trust me when I tell you that they are completely sealed! If you don't believe me, check out Branfordbike.com. The only real problem is only for those folks who have italian bb shells, since it only comes in english. They cost about $10 more than a D/A BB and Quality actually has plenty right now!

and it's also over 40% heavier than the regular Dura-Ace... It's a really nice bottom bracket, but there are reasons to use the regular Dura-Ace. If people can't handle the fact that you can fine tune it to get it not just right, but perfect on the bearing load, then maybe they shouldn't be riding top level parts. Not that I am trying to sound elitist, but the top of the line stuff isn't for and shouldn't be for everyone. The Dura-Ace bottom bracket is a perfect example, and while I can apprieciate that you and others are trying to give options to it, be fair and explain both sides of the issue to people.

The Dura-Ace track bottom bracket is like the older Dura-Ace cartridge BB but with the Octalink Spindle instead of the Square Taper Spindle. It's simplicity comes at a price of a drasctic weight penalty. On the other hand, the weight savings of the BB-7700 (reg. D-A BB) comes from the use of a non-cartridge system. Ease of installation and maintainence is sacrificed for light weight and adjustability.

And by the way, cost should not be an issue... under every distributor that I have checked, they are the same wholesale cost. (well at Quality the Track is 30 cents more... close enough)

Just setting the record straight, and don't get me wrong, the Track BB is still a great BB, but it's heavier and less adjustable.... for some, that is not a disadvantage, for others it is.

you didn't tell the fine folks here on the board that the drastic forty percent weight penalty is 47 grams! That's less than two ounces! The regular D/A is 173g and the Track bb is 220g. You can argue until you are blue in the face about the superiority of the regular D/A bb because it's serviceable and adjustable but the vast majority of folks actually want to ride their bikes, instead of leaving them at the shop to have the bb serviced. And to be honest, once you put a bb in a frame, why should you have to adjust it? You also used the word simplicity like it was a bad word. In most circumstances, the simple way is the best and easiest! The steel lockring is also better because, God forbid, if there is ever a time that I can't work on my own bike, I don't want some chucklehead college kid who works at a shop destroying the non-drive cup and dicking up my frame if the bb should go bad!
