Quoted message said:I am rebuilding an old Trek 400 touring bike and I'm trying to piece it
together with a bunch of random parts that have been donated to me and
a few that I have purchased used. So, I have a shimano 600 rear
derailleur and double crank. I am in need of a set of shifters, and I
am hoping that I will be able to use STIs as opposed to downtube, but I
would also prefer to use whatever will work the best. Also, I have a 9
spd cassette that I would like to use because I've had it laying around
for a while and don't particularly want to buy an 8 speed.So, I have some questions about the compatability of
derailleurs/shifters/cassettes. What makes the drivetrain a 7/8/9
speed? i know the shifters are important, and clearly the cassette is
vital, however, are rear derailleurs specifically made to be 7/8/9
speed? Or, if I found some 9 speed shifters and put my 9 spd cassette
on the bike would the old shimano 600 derailleur work just fine?
No derailleurs are not made for different speeds. What you need to check
is that the 600 derailleur is index compatible. It should say SIS on it
somewhere.
Quoted message said:Also, a question on the front derailleur. I have a shimano 105 front
derailleur (again, a donation...) coupled with a shimano 600 double
crank that I picked up down in Boulder for cheap (goes on the old
square botton bracket). I put the crank on last night and noticed that
the derailleur didn't extend out far enough. I adjusted the hi screw
and it is out as far as possible, and it is still not *quite* far
enough. Can I get some sort of spacer or something or do I need to get
a derailleur made to go with the shimano 600 double crank, such as an
old shimano 600 derailleur.
Are you sure you are using the proper BB for the crank? Using the wrong
BB could cause the problem you are experiencing.
