hi, i am wondering if it is possible to adjust the speed of the rear derailer(spelling?) as it down shifts. if so how do i do this? thanks...err.. i mean as the spring pulls the derailer down from the lowest to the highest gear, big to small.

there is a slight lag as it goes down, i would like it to be a touch faster. i had heard somewhere that shimano derailers came with the spring in the slowest return posistion. if its possible i'd like to change it.

Some derailers have a bit of adjustment for the spring. Might also be a cable/casing/lube issue or slightly too much cable tension.

On the mountain side of things, XTR is the only one with an "adjustible" spring that I have seen. It is almost an impercievable difference one way or another. I have long been a proponent of shimano beefing up thier springs, which is an aspect in which Sram has them quite well beat.(Though I still have an XTR rig).

One oft-overlooked consideration is your cable. Stranded/braided cables grow in diameter as they corrode internally from moisture. This in turn will cause drag on the housing, reducing the spring's effectiveness.

Stainless cables now in common usage don't do alot of 'internal' corroding.

I beg to differ. I replace stainless all the time. It is merely slower to corrode but still falls in the same rules since it is after all, steel. Teflon-impregnated, however is sealed well enough to not be a concern usually.

For mine, I can justify 8 dollars per cable. Customers get sticker shock when they see the other is only 1 buck.
