I'm new to the BF forums and am trying to work out a problem with my Shimano 105 triple front derailleur. I bought a NOS Cannondale T1 last fall with the intention of doing some touring. The bike came with Ultegra Flightdeck brifters, 105 road triple (50/39/30) and 105 FD, 10 speed (11 - 32) casette and a long cage Ultegra RD. The setup worked very well with the rear setup shifting very quickly with a nice click and a light touch of the brifter. The front setup shifted almost as well except that it took more effort to make the shift from a smaller to a larger ring against the spring and when downshifting from larger to smaller there was more of a clunk than a click in the drivetrain. But the system worked well.
I made some significant changes to the drivetrain over the winter to more reflect what I want to do with the bike (tour with a trailer) and to shift the the total gear range lower. I kept the rear setup but swapped out the 105 road triple for a Sugino XD2 46/36/24 triple, kept the 105 FD, changed the compact drop bars for bullhorns and am now using Silver bar end friction shifters.
The setup works well except for the force required to move the 105 FD against the spring when shifting up and the amount of shifter friction required to maintain the derailleur in position. In other words, the FD spring seems to be overly stiff for the present shifting setup. It works but I don't consider the setup to be optimal.
There is no way to adjust the spring tension lower on the 105 FD and was wondering if there is a derailleur out there that will work better with friction shifters than the present setup. Obviously, indexing isn't a factor. I was looking at the IRD Alpina FD as a possible option. It comes in a model for either brifters or trigger shifters but what I really need is something that does its work with lower spring tension. Thoughts? AL
