SSS spanner wrench

[beastie]

So, you SSS guys, is there a cheap place to get these spanner wrenches? Size might help, I know Harbor Freight carries stuff like that, but what size do I need?

Or is there a way to adjust without the tool?

Getting my sprockets and chain in soon but don't have the spanner.

I hear a big flat head screw driver but that doesn't sound too good for the parts!

Thanks

if the eccentric is loose, you can move it pretty easily w/ a screwdriver.

in fact, i think i had a post on TOB regarding how to do it w/o a hammer...

let's see if this still works:

aight, here we go...

first of all, be sure and loosen these:



now, if you had your chain guard off, you could see the "teeth" in the adjuster. they look like this:



now, you should be able to slip your #3 flathead screwdriver (perfect fit, btw), through your sprocket like this:



perfect fit, see:



move your wheel cw or ccw to adjust.

if you can't move your eccentric like this (or beating on it with a hammer), you've got bigger issues.

Ohh, I see. So that's what they meant by using a flat head screwdriver. I thought it was tapping on it from the top, now that would damage the teeth.

I'll have to check because I got a Quick Release carrier on mine and got to make sure I can slide something through.

Thank you very much to you man

you can pick the wrench up from various sources on ebay for about $20. It makes the job REALL simple. I'd highly recommend grabbing one...
I bought mine from a store called "Podium Racing." Couldn't be more pleased.
In fact, he has a couple up right now.
Here's his for $17 w/ FREE shipping.

yup... right tool for the job...

That screwdriver method assumes the eccentric will move easily; it doesn't. I used a proper wrench and it required a bit of muscle. With the very limited leverage you would have with a screwdriver through the sprocket like that I doubt you could get the eccentric moving at all without the use of a hammer. Even then, an accurate adjustment would be difficult. You really need the leverage provided with the proper tool.

as i said above, mine moved rather easily. how loose were your pinch bolts?

i also have the proper spanner and "over-adjusted" because it moved so easily.

fwiw, the screwdriver method would theoretically provide more leverage since you would be using the wheel/tire as an "arm" to move the eccentric.

Yup, pinch bolts were removed completely and the eccentric was stubborn but after I got it loose it easily adjusted with the wrench. Took some muscle at first though even with the wrench. With the screwdriver I can only imagine the grunting and groaning it would have required. I overadjusted mine as well, a few times. But the great part is you can correct it just as easily by turning in the other direction. It's easier to control the spanner wrench though. If I had to adjust my chain and had no spanner on hand I'd do the screwdriver thing but since I bought the spanner with my bike I can explain why it may be the preferred method. Some people adjust their preload with screwdrivers as well when a proper spanner is available. Spanners= easiest & best. Screwdrivers= work in a pinch but not as articulate.

I bought both my eccentric wrenches (one for chain tensioning and the other for rear shock adjustment) from bevel heaven.
