i just got done servicing my shifter/cable/housing/rear deraileur (that's Deore shifter/XT deraileur)... lubing and cleaning, taking off cable-o's, changing ferrules, cutting down the stock housing, and i decided to throw on an Avid Rollamajig i had laying about, just for kicks...
well, i got to shorten that loop of housing at the deraileur about three inches, and replace the bend with a smooth pulley. it feels damn good now! best $10 (retail) drivetrain toy i've found yet. friction reduction is very noticeable.
i'll have to ride with it tomorrow, and see how it goes, but it seems like everyone should have one! i think an Ultegra 11-23 road cassette is my next experiment...
