STI shifters for XT drivetrain?
« on: September 19, 2004, 04:07:31 am »
I am in the process of ordering components for a Rivendell Atlantis frame.  I want/need the gear ratio of XT gearing but would like to use drop bars with STI ultegra shifters.  Any experience with this good or bad?

   I built up a Jamis Nova frame with a XT crankset and cassette using a XT rear derailleur and a Dura-Ace front derailleur and Dura-Ace STI shifters, and it works fine. I put a chain keeper on the seat tube so the chain won't drop off when shifting to the small chainring.

That's basically the setup our Santana tandem has.  Works well.  A chain keeper helps some.  Tweaking by a good bike mechanic (like Mark at Walt's Bike Shop in Columbia, MO, if you're ever by this way) helps more.

i have a jamis nova built up with full xt as well, not an issue. i am using ultegra sti shifters with v brakes as well.

jim what rack do you use for the front? i have a transit front rack i use with rei panniers on the front and back but have issues getting them on the front easily. just curious what you have going.

STI rear shifters will work with almost any 7,8 or 9-speed road or MTB rear derailleur and with any cassette with the proper number of cogs. The only exception is 8-speed Dura Ace and you are unlikely to have to worry about it as it has been obsolete for years.  

STI front shifters require a road front derailleur to index properly.  However, this isn't a problem as road front derailleurs work fine with chainrings much smaller than they are designed to mate with.  For example, an Ultegra triple front der is designed for a 52T large chain ring but shifts fine with an RSX triple crank with a 46T large ring.  My son's older Trek 1200 came stock with this type of setup and shifts very well.

I do only light (Inn to Inn) touring so I just use a rear Jaand rack and panniers.

Ok, just want to put my .02 in.  Do a google search on STI failure, STI repair, STI broken, etc.  I didn't believe it until my right Dura Ace (the $$$) one stopped shifting.  I would go with Campy, and that's I did.  As for the rest of the drivetrain, Shimano all the way for cost and durability.  Besides, it was a full DA bike.  Jtek engineering makes a ratio changing pulley that lets campy levers shift a shimano drivetrain, or visa-versa.   Besides, there's no cables to interfere with a handlebar bag on the campy brifters.  Unlike the bike on the front of the latest Adventure Cyclist magazine. :)

I have STI/Campy ergo on most of my bikes, but on my Atlantis I went with DuraAce bar cons...I am very glad I did...for a million reasons, but mostly with the friction option, I am sure they will always work, no matter where I 2 cents....
