I'm really sorry if this is a bit redundant but I tried searching the forums and good ol google with no luck.
Basically, I want to use Ultegra 8-speed bar end shifters on my 7 speed bicycle with what I am assuming are MTB gears. Harris Cyclery's website says I should not have any problem with 7-speeds and I am using Rivendell Albatross handlebar that fits into MTB clamps(25.4). The handlebar accepts bar end shifters. I just have no idea if this will be compatible with my SIS 7 speed rear X 3 speed for the front ones. The specs for my gears(more or less) can be found here: http://www.epinions.com/bike-Bicycle...ay_~full_specs
tia to those who can help me! Much appreciated.
