E.13 Lg1+ Rubbing, Anyone Else Had Problems With Setup?

[White-Lightning]

Hi
I just brought a 2009 E.13 LG1+ chainguide and installed it today, the installation itself was a breeze, top marks e.13 . But the problem I now have is that when I am either my highest or lowest gears (11-34 tooth cassette) the chain rubs on the upper guide, not badly but a bit annoying, I thought that it may be down to the fact that I have a "all mountain" cassette on but really, no matter what the size of the cassette, when the chain is in the highest/lowest gear it is still going to be just as far out line with the top of the guide as a "dh" cassette because they are all the same width. so my question is, how do you dh'ers that have an LG1+ run them to keep them from rubbing? is it all to do with the spacing?

at the moment the guide is spaced so that when I am in gear 4,5, 6 the chain-line is straight (I am guessing this is the correct position ?).

any tips/help would be appreciated .

I'd say, when you look at the drive side from the side, its tilted too far anti-clockwise, so the guide isn't far enough round the chainring, as far as I can think anyway. I may be wrong.

what bb and wheel spacing combo? I would think this would be more of the problem than the guide. i.e. 73mm and 135mm will rub on pretty much anything.

you take an old SRS i got and I'll have the LG1...that'll fix it.

We did look at that and rotated the guide around a bit further than what e.13 recommended because it seemed that the more you did that, the hole/opening at the top of the guide increased but we cant rotate it anymore because of the chain stay.

yeap its a 73/135mm. why would that cause any extra problems? would I be able to space it out at all using bb spacers?

I have the same thing going on. No real fix for it, it get alot worse when you ride in the wet and get mud and shit on your chain. You get used to it after a while.I don't notice it at all now except when the bike is in the workstand.

Nope, its already too far out and it is makes the chainline less than ideal. Pretty much you'll just have to live with it, you could face the BB down to 68, (2.5mm off each side) but that would take ages.

Ok. And by facing the bb down that solves problems? what about the fellas that run a 83mm shell? do you think I could file the edges of the top guide down just a tad so it is wide enough to accommodate the chain-line?

Hard to tell without knowing the bike, but it would definitely reduce the rubbing. Most 83mm bikes have 150mm rear wheels. I get a little rubbing on my Sunday (83mm , 150mm) when at the very top of the cassette.

oh sorry, 2007 sx trail. bike to go overseas with me. So is it because I have a small rear wheel that the size of the bb is pushing everything out of line? do you think I could file the edges of the top guide down/wider just a tad so it is wide enough to accommodate the chain-line? it wouldn't have to be a drastic alteration but just a little bit.

Can't see why not, some modding would most likely help.

Hey Bryn run your bike 8 or 7 speed. that would solve it

may have to give it a whirl then .Thanks very much for your help .

Hey Ryan, so just take off the top/bottom cog and adjust it then? I don't have the cash to do It any other way...

[moonbouncer]

Yea man you replace top and bottom cog with a spacer and the look your shifter out then you have a 7 speed bike. (what all the cool kids are doing these days)

[wuffy]

4 Speed on a DH rig is ok. But 7 Speed on an SX trail? Really? I would've though it'd be a bit limiting if you did that.
