Ultegra STI Question. Going to a double from a triple..(16 posts)

Ultegra STI Question. Going to a double from a triple..bikenj

Going to a double from a triple, can I use the same shifters?

The right/rear shouldn't be an issue, but what about the front?

They are the same..GeekRoadie

You should be able to use the same shifters. I've done the opposite on two of my bikes (triple -> double). The same goes for Tiagra and 105. Adjustments for the conversion are all made on the front mech (limit screws and cable tension). The shifters "trim" position in a double config turns into the middle ring position for a triple setup.

they are not the same!the bull

There is a upgrade kit.
It includes crank,bottom bracket,frt and rear derailleur and the left sti/brake lever.
The kit goes for about 450 dollars you could find it for less if you shop around on the net.

I bought a Kona cyclocross bike and it has the same shifter I had on my triple crank cannondale bike. You have that extra click which helps fine tune the 39 chainring.

I nevered had to use the third click yet. I was surprise that you could use one standard shifter considering how shimano likes you to buy new parts to get what you want.

Just one thing...Matno

It's not necessary to change the rear derailleur. If you are switching from double to triple, you will need a longer rear mech, but it's not necessary to switch to a shorter one when going from triple to double. You'll just have more chain than you need, which adds weight.

You can get the whole "kit" that you describe for a HECK of a lot cheaper than $450! That's a ridiculous price (I paid less than that for my whole CAAD 4 bike with all 105/Ultegra parts!) Crankset and BB on EBay will run you about $120 for a new set, just the left shifter usually goes for about $50-60 new, front derailleurs cost $20-25, and the rear derailleur (if you want it) will run you $25-35. Total cost: $215 if you're patient. Then you can subtract the price of the stuff you are taking off by selling it on eBay (pretty close to the same as the stuff you're buying assuming it's in good condition). With eBay you can practically get a straight trade (less shipping)! I recently parted out my 10 year old Schwinn SuperSport (which I originally bought for $200) to fund a Cannondale CAAD 4 with all 105 drivetrain, Ultegra/MA3 wheelset, Ritchey WCS bars, Bebop stainless pedals, Koobi Xenon saddle, Easton CT2 carbon seatpost, etc. And my total net cost came out to $433! That's hard to beat. Almost everything came from eBay and all of it is brand new or really close to new.

my price is about what a lbs would sell it for !
If you even read what I wrote then you would see where I said you could get it for less IF you shopped around on the net.
As for all you other hacksaw hammer holding shot-cut mf's
you can rigg up anthing you like but I take pride in my work and when I fix something I fix it right the first time.
If I give advice to you it would be the best way to fix it.

Either way it's the same shifter for 2002 and 2003. Read my below post, it has the Shimano hyper-links in it that explain it.

Seems for once Shimano made things easier instead of harder on the upgrade crowd.

Thanks, I've purchased everything I need to upgrade, except the lever if that is in fact an issue,

the STI's were compatible either way (double or triple). No need to purchase new left STI. My understanding is that this is NOT the case with Dura Ace.

Having said that, I just looked in the Colorado Cyclist catalog and see that the Ultegra Triple Upgrade Kit includes new STI levers. Maybe the newer Ultegra has different shifters for double and triple???

Good Luck,

I believe the 105 level shifters are compatible with both. Same goes for the new 2003 Ultegras (there is only one model listed on Shimano's website, the 6510, and no mention is made of double or triple). The previous models I think were double or triple specific 6500/6503. I don't really know, but that makes sense. Somebody correct me if I'm wrong.
why not turn out outer limit screw, take off chain and see? nmjiggs

The Triple shifter will shift a double....russw19

The triple shifter will shift a double front... it will have an extra click. Just set up the front derailleur properly so it doesn't throw the chain into the frame or over the big ring. And you have to play with the tension a bit more than with a double shifter/double chainring set up. When most people set up double levers there will be two clicks when dropping from the big ring to the small ring. The first is the trim adjustment click, the second drops to the small ring. With the Ultegra levers there are two trim adjustments... so to go from big ring to small set up as a double, you will click once for trim, once to drop down, and once more for trim if you are on a larger cog. This sounds way more confusing than it is, but the shifters are the same, just set them up right and you won't have a problem. Read the Shimano tech links below.. it makes more sense.

Here is the Shimano part listing... it shows the same for double/triple front shifter...

Also, this covers the trim feature of the 6510 shifter (Ultegra)

That should cover it... but the answer to your question is yes, you can use the same levers if you convert from a triple to a double.

thanks russ! this is the answer!nmthe bull
