[RBW] Hookin' up shifters question

2013-10-01 Thread ascpgh
What I've done for years when initially fixing the long end of a cable (range 
of motion limit screws roughly adjusted to hand manipulation of derailleur 
before chain  put on and barrel adjuster all the way in then backed out one 
turn) is to feed it through the housing and ferrules, making sure all are 
seated nicely to each other (just fitting them snugly) and when I am pulling it 
to the cable clamp, instead of pliers or third hand tooling it to get more 
tension I deflect the derailleur against its spring action with my hand when I 
tighten the cable clamp. The derailleur spring pulls any overt slack and then I 
give the shifter a push through a gear or two's range of motion and let it sit 
for a bit to really seat the ferrules on housings, and both into the stops. No 
funny kinks or smashed placeson the remaining cable.

[RBW] Hookin' up shifters question

2013-09-29 Thread Michael
Putting Albas with fric/sis bar ends onto Bleriot. Hope to be able to 
friction shift though over the 10-speed cassette.
 
*1. How hard do I pull on and hold the shifter cable when I tighten it down 
with the bolt on the derailer?*
*Really hard, or just pull gently to its full length? How do I know the 
cable tension is correct?*
** 
*2. If I need to use the barend's indexing option because it just wont 
friction shift over 10 well, what else do I need to do for adjusting cable 
tension for SIS?*

Hi Michael, the derailer cables don't need to be super tight to begin
with. In the first position, just pull it hand tight. I mean pull it
pretty taught, but you don't need to worry about it. They shouldn't be
sagging at all, but don't need any more than that. I know that's
pretty vague, but can't think of a better way to explain it without
showing you IRL :-)

Just get it taut enough -- I use needlenose pliers to pull it gently. If
the chain won't move to the smallest cog, and you've properly adjusted the
High throw screw, then back it off a bit. It won't matter if it's wee bit
loose, for friction, as long as the lever has enough throw for the entire
cassette.

For indexing, use the barrel adjuster on the derailleur to get the
derailleur positioned correctly. Start by getting the chain to track
precisely on the middle cog and then run the chain up and down, adjusting
slightly as needed. You don't need to turn the barrel much once the
derailleur is close to the right postion.

I'll be curious how it does with 10 -- I shift 9 with no problem, and I
shifted 10 with a Simplex Retrofriction dt lever -- but the Retrofriction
had the advantage of (1) a small barrel for precision and (2) the best
clutch mechanism of them all -- better even than the Silvers, IMO.

Finger tight is good to start with. Get the barrel adjuster to mid-point to 
begin with so that you can go one way or other after the fact. You may want to 
adjust for indexing first and see how that runs. If it shifts indexed, I can't 
imagine it not shifting manually. Go through the gears on all chainring 
combinations on the stand...multiple passes. Listen for any problems and 
observe whtether the deraileur want to shift on it's own in a particular gear. 
That will give you a good clue about too loose/tight a cable is. Good luck.
