Top pull derailleur for Ultegra triple crank?
Has anyone successfully used any top pull fder on the Ultegra triple?
Is there any gizmo available to route a top pull cable so that it can operate a bottom pull fder? Was thinking of maybe a seat tube clamp with a pulley on it so the cable comes down and around the pulley to the fder... |

Top pull derailleur for Ultegra triple crank?
L smythe- Has anyone successfully used any top pull fder on the Ultegra
triple? BRBR Saches..but they are 'no mas'.. Is there any gizmo available to route a top pull cable so that it can operate a bottom pull fder? BRBR Use a shimano e-clamp and then mount a 'cross' pulley onto it...we do this all the time.

And what is a 'cross' pulley? Very interested in getting this solution... |

L smyth- Not sure what you mean, do you mean to use a fder clamp that goes on
the BB? And what is a 'cross' pulley? Very interested in getting this solution. BRBR A shimano e-clamp is the thingy for shimano mounted to the BB shell fders that stabilized them. Use just the clamp that has a drill hole in it, Mount a tyipcal fder cross pulley to it, mount assembly to the bottom of the seattube, route the top pull cable down, around the pulley, attach to bottom pull front der.-About $24 or so for both.

Top pull derailleur for Ultegra triple crank?
bikefixr- But why not just use a top-pull front
deraileur? They do work. If you use a thumb-shifter, move the cable to the inner position on the pinch bolt to get greater throw. BRBR With ultegra or any other road STI, with a MTB top pull front der, they do not work.

Top pull derailleur for Ultegra triple crank?
I am in similar situation to the original poster, but I'm using a double crankset, and I'd prefer to use a top-pull derailleur rather than a pulley with a bottom-pull (and I don't need to worry about STI, as I'm using bar end shifters). My problem is finding a modern top-pull top-swing derailleur that will shift either a 48/38 or 48/36 set of double chainrings. I tried the current XT, but since it is designed for mega-9 drivetrains, it wouldn't work (the inner cage rubbed against the smaller ring when shifted to the large ring). I've heard that the old style (pre compact-drive, mega 9) derailleurs will work with these larger chainrings, but does anyone know which particular derailleurs will work for me? Better yet, does anyone know where I can find one? The specs of the recent XTR front derailleurs indicate a large ring capacity of 48 teeth-- does that mean this derailleur (the M952) would work better for my application than the current XT?

Thanks for your help, Peter! However, I do NOT plan on using STI, so will these mountain derailleurs just not work for 48/38 or 48/36 double setups, even with bar end shifters?

I tried the current XT, but since it is designed for mega-9 drivetrains, it wouldn't work (the inner cage rubbed against the smaller ring when shifted to the large ring). BRBR It's not completely the arc of the cage but also the arm length and dimension of the fder, that makes it not compatible with road STI. No MTB front der will really work..need a Sachs road top pull, NOS now, tough to find. michael The specs of the recent XTR front derailleurs indicate a large ring capacity of 48 teeth-- does that mean this derailleur (the M952) would work better for my application than the current XT?
