Ultegra vs. Dura Ace(12 posts)

Ultegra vs. Dura AceLowCel
Sep 18, 2003 5:18 AM
I have been running Ultegra for a couple of years now. I just bought a new bike a couple of weeks ago with Ultegra. I have a chance to upgrade to Dura Ace really, really cheap in a couple of months. Actually, free, a buddy of mine is changing from Dura Ace to Campy and is planning on trading me his Dura Ace for my Ultegra. Then just selling the Ultegra.

His group only has about 300 miles on it. I will be getting shifters, brakes, derailleurs and bottom bracket. Will I notice much of a difference?

If it matters, my bike is a 2003 Giant Composite TCR 1.

Thanks in advance.

You'll definitely notice a difference in both shifters.OldEdScott

You'll notice that the BB will be more work, because you have to maintain it. Whether you notice the rest of it depends on how sensitive you are.

Dura ace is feels more confy in the hoods then ultegra IMHO. the shifting is also crisper but they both function really well. Next year Dura ace will be an order of magnitude better.

Your 2003 Giant Composite TCR 1 is worthy of DA, and there is some weight savings. You could always keep the Ultegra BB if it concerns you. The real difference, of course, is simply KNOWING that you have DA rather than Ultegra ;)

Shifters - probably the only difference you may 'feel'. The D/A shifters are a bit smoother in their action and the shifting will feel just a bit "crisper", especially with the D/A rear derailleur.

Brakes - IMO the Ultegra brakes are a bit more powerful and stiffer than D/A. My bike started out full D/A and now has Ultegra brakes - I think they stop better as there's a little more heft to the caliper.

BB - Do a search on this. If you don't like to maintain your bike, keep the Ultegra cartridge BB. Dura Ace will need periodic servicing, especially after wet rides as it is a high-tech, but more traditional (non-cartridge) BB. The D/A is a better BB, but will not last if you don't take care of it. That is the main difference between the two. You won't notice a thing while you are riding.

300 miles is nothing for components. I wouldn't worry about that a bit.

Good luck.

I have a DA bb in one bike and Ultegra in another. The DA was only slightly more trouble to install (it actually has to be adjusted instead of just popped in like Ultegra), but it is significantly smoother. With the chains off the DA will spin for days, and the Ultegra stops spinning much sooner. I'm a big fan of cup and cone style bearings. If you don't mind the hassle of adjustment I think they are the way to go.

Thanks everyone. Looks like everything will work out pretty well. I am going to stay away from the bb though. It's not enough of a weight savings to make it worth dealing with the hassle.
How much water is too much for Dura Ace BBt-moore

I hear people talk about the constant adjustment that the Dura Ace BB needs if you constant get it wet. Are you guys talking about riding in the rain for hours reguarly. Or are you talking about riding through wet roads occasionally.

When I bought my Dura Ace cranks, I wanted to get the Ultegra BB, but they were out of stock. I bought the Dura Ace BB on the cheap. I assume that riding here in SoCal that I don't have anything to worry about. Do I have it right???
Even a puddle is enough to require servicingLC

If water gets in the frame, it seems to get sucked right into the dura ace BB. On the bikes I tried it on, it turned into a water bearing. Maybe it would work better if the frame had good drain holes right under the BB?

It does have a drain hole. Just unscrew the cable guide screw and water will come out. I got caught in the rain several times this year and last time I checked, the BB was still dry. I do check the BB regular though.

The only component that is OUT AND OUT better with Dura-Ace is the STI shifters. Otherwise it is just a few grams and better finish.
