|Road Tripple / Dura Ace... HELP||paddlechris|
Jun 2, 2003 1:43 PM
|History.. I have been riding road for about 17 years. I am about to "re do" my road bike with new paint and some new parts. My problem is.. I prefer a tripple, and I want the best one I can get. I also have been ridding on the same Gear combination for years and would prefer not to change them.. Front a 28,38,48 and a 12-28 on the rear.
First can anyone tell me anything about the Dura Ace Tripple, I can not find any reviews anywhere.
Second... is this gear combination possible??
Third is there a better option
Any help would be great Thanks Chris

|I have the D/A Triple with a 50/39/28 front & 12/23 or 12/27 (depending on where I am riding) on the back. I Love it. To your questions:
Second... is this gear combination possible. To get the chainrings I wanted, I had to use T/A for the 50 & the 28. D/A smallest big ring is 52, Middle is only available in 39 & 38 and the only small I found was the 30 that comes with it. That being said the T/A rings work great. I got them at Peter White cycle. However, the D/A front Der is designed for the 14 tooth drop from the Stock 53 to the stock 39. My LBS recommended the Ultegra front Der for the combination I wanted (50/39/28). It works flawlessly with the D/A shifters. It's a little tricky to set up to avoid chain rub (tight tolerances). If you are doing it yourself, take your time, but once dialed in it's great. Longer chainstays help also (as the chainline angles are not as severe).
The D/A shifters and rear D/A Der work great. Smooth, easily feathered and very positive shifting Front Der shifter has multiple positions for each ring, so you can feather out un wanted chain rub. BB is sealed so is easier to maintain than the regular D/A. Brakes are standard D/A as are the hubs.
Largest D/A cassette available is 12/27. Shimano does not recommend larger than 27 for any of it's road triples. That being said, I have used a 30 with no problem (Just make sure you have enough chain). If I want to go larger than a 30 (32 or 34) I simply replace the rear Der with an XT or XTR 9 speed mountain Der with absolutly no problem. Once you get it set up once, the change takes about 10 minutes.
If you have the money, I don't think you will be disappointed.

|If you want to stick with shimano chainrings, you might consider going with a 110 bcd crank with XTR rings. I recently put together a cross bike, and got an AC crank and 110/74 spider from cambriabike.com (uses a splined XTR bottom bracket). Got XTR chainrings from excel - 48/36/26. I ground the cage of an ultegra FD to match the tighter curve of the 48, but it might have been fine unmodified. If you go with Dura Ace, remember that the small chainring bolts to the middle chainring, not to the crank - this might severely limit your options if you want to swap a different middle ring. I think the small chainring is also a non-stander BCD, so you might be limited there too. An Ultegra triple might be better if your not sticking with stock chainrings. Or just order one of these: http://www.peterwhitecycles.com/zephyr.asp with whatever chainrings you want.|

|I've been very happy with the DA triple. Can't help you with the chain ring inquiry... I've got the stock 53/39/30. But the snappy shifting has been a noticable improvement over the Ultegra (which isn't a shappy setup in its own right).|

|I road a custom road bike from 1984-2000. I had a custom drivetrain much like you have. When I started looking at new bikes (I wanted index shifting), I quickly realized that the only way for me to have the same gearing I was used to was to use mtn bike components. Instead, I bought a bike with a Shimano Ultegra triple and now find that I mostly use the middle chainring and seldom use the big chainring unless I'm going downhill. The gearing options just aren't as prevalent today as they were in the early 1980s, unless you don't mind mixing mtn & road pieces.|

|I have a DA triple on a Y-Foil and hate it. Over 5,000 miles on it. I am certain the parts are not manufactured correctly. At least half the time, while shifting from the big ring to the middle ring, the chain will go to the small ring. I have now had this adjusted in 7 shops and they tell me there is nothing they can do. They do suggest going to an Utegra - probably wrong spelling.|| |
