are all chain guides the same?

My sister got me a bashring for my birthday. I'm in desperate need of a chain guide now as I keep dropping the chain with my 1x9 setup. I'm not leaving the FD on.

So... my question is... are all chain guides the same? I mean, if I buy one off the net, will it be compatible with my bike? I have a 32t ring up front. Raceface XC Ride crankset.

Thanks!

No they are not. There are different mounting styles, sizes, and other various options. Do a little research. With a single ring front you have a lot of options. MRP, E-13, Gamut all make good guides that you might want to look at. Look around their websites for applications.

If your 32T chainring was taken from the middle of a 'triple' it will have shifting ramps which will drop the chain easier without an FD. It also plays to change the chainring to a proper 'single' with higher teeth and no shifting ramps.

even with a ss ring you can still drop the chain, although you should be using a proper ss ring you can still get a chain guide if you like

but yeah as said above all chain guides are not the same, and as said above dif mounting styles tooth capacity, single vs dual ring ect, but i imagine your question was more of a "why should i drop $100+ on an e-thirteen when i can get the blackspire or truvativ guides for $25" Well I'm not and expert but i've heard that noise is one issue, as well as reliability and general build quality ect ect,

I can tell you this, i jut got an e13 DSS and seems to be pretty awesome (btw e13 has this new line of less expensive guides made of stamped steel instead of alloy) I cand fathom my chain dropping now, and it didn't add any noticable noise as its quiter than the chain moving through my rear derail

Okay you are going to need a blackspire stinger they are twenty bucks. You will need the BB mount version. Is sandwiches under your drive side bb cup and holds out a little wheel to put isolate the turkey neck slap wave that derails your chain from the bottom. You will need to remove your crank and botom braket to install it but it is very easy to do with the right tools.

All chain guides are not the same. Most of them are like stingers but 4 times as heavy and 6 times and costly and come with a crappy plastic bash ring.

jump stop with an unramped ring (i like the surly stainless rings) and as short a chain as you can, and you're good to go. the stinger guide from blackspire works great, but is meant more for a 2x9 system. though you can use it just fine with a 1x setup, i think it's overkill.


more than anyone wants to know about.

Have you ever used a higher end chain guide or a polycarbonate bash? And the Stinger is a dual ring guide sure it will work but not as well.

Yes and yes.

I didn't mean to offend users of polycarbonate bash rings. Just, you know... plastic ones.

okay.

yes, the system WAS a triple crank, and now i use the middle ring. I already have the bashring and my problem is dropping the chain on the inside (obviously).

I was planning on shortening the chain and slapping in a powerlink... wasn't planning on buying a new ring... just a chain guide.

I phoned the guys at my LBS. they said the stingers support the chain only from the bottom (which i gathered from the pictures), and are mainly used for 2x9 or 2x8 or 2x w.e. setup, not a 1x setup. The guy on the phone said i should go for a box guide since stingers are supposed to be used with a FD. I can get box guides at the LBS for ~80$...

another thing i'm noticing is that all these chain guides are meant for a ring minimum of 34t. I have a 32t. does this mean i have to upgrade my ring as well?

If you're willing to go the price of an e.thirteen, the ST guide has a BB cup adapter, is 32T compatible and is designed for a single-ring system.



Of course, those looking for serious bling might check out the Syncros CF guide and chromed alloy bashring .

hey scrub,

i re-read your post and thought about it some. a proper chainring and the jump stop would be cheaper than buying a chain guide. Also seems lighter (which would be an extra bonus). Do you actually run a 1x setup that was formerly a 3x setup?

I don't want to bank on "it would probably work," as I just spent much of my luxury money on tires (they're kick ass tires btw).

$80 for a boxguide seems steep to me, I assume your talking about a truvativ boxguide, depending on the model ur lookin at i see em online for $30-55, and you can get an e13 ls1 for about $50 which i believe has a better roller design and a better plastic dohicky that the roller is between at the bottom

as far as working with 32t rings, I think a 34t compatable one would work ok, As far as i can tell from my guide, using a 32t ring would just mean the bottom roller was a little farther away from the ring and if using a 32t bash, the gap between the plastic dodad and the bash would be bigger, theoretically this could effect perfromance by allowing more play in the chain or somthin, but i doubt you will actually have any problems, especailly if you are considering a jump stop (I assume you can't be doing anything to crazy)

also i've got a jump stop on my 1x9 cx bike that is an old tripple crank, it mostly works, when actually cx riding i don't have any problems, but when i take my cx bike mtn biking I drop the chain once and a while what happens is the chain jams into the jump stop and flexes the thing out of the way, or it just derails from the bottom not the top (prolly the more likely cause

He said hopefully. Like clever mice, if there is a any crevice to exploit, a chain will find room to jump and derail; you can count on it.

yeah i rofled, keke mice.

but he's also got a good point, however, since the op is considering a jump stop, and just got the bash, i can only assume that this is not for freeride ect, and that a 34t min guide will at least be more reliable than a jump stop, but yeah unless the op changes the ring it prolly won't be foolproof

so if i went for a truvativ box guide BB mount, that'd do the job? I can get one off price point for ~45$ + ship, or used for ~30$ if someone responds to me.

no help there, but yep, my 1x setup was a 2x for a long time. i swap back and forth sometimes. short chain + unramped ring + jump stop inside/bashring outside works just fine on the chunky stuff around here.

they key is have your chain on the largest dog in back, then setup the jump stop as close to the chain up front as you can without having it rub.

the guys at my lbs said that to attach a truvativ box guide i'd have the shave off the nubbies that allow me to attached my granny gear. i'm not interested in that, so i think i'll go with the next best thing: a n-gear + shorter chain + proper gear. Do stingers work on 1x setups?

Another reason to maybe at least check out the e.thirteens. Not always necessary with those - - and that comes from DW himself:

i tried shortening the chain. now i'm dropping it whenever i'm in the three smallest cogs at the back... so that certainly doesn't help. I just ride down the road and it fails.

do it right get the e13 http://aebike.com/page.cfm?action=de...=30&SKU=CH1351 I can't tell if thats the one that works on bb or if you have to have the iscg tabs. But the new e13 stuff is now in the qbp book, so any lbs can order it for you (prolly cost a tad more, i doubt they even know this exists cause its pretty new, prolly why they recomended the boxguide

how do you mount these things on the bb? I took a look at my bike... there really isn't anything to anchor it to. How do these bb-mount chainguides stay in place?

edit:

actually i'm going to place this question in the mechanics section.

^ you take off the drive side of the bb, put the bb through the big hole of the tentioner, and screw the bb back into teh frame, you may have to mess with some spacers (they come with the guide) when you tighten the bb, the guide plate gets sandwiched between the bb shell and the frame holding it in place, it can be a little tricky to get the angle of the guide right but its not too big a deal
