Chain Device Help

Postby mcnultycop » Wed Jan 02, 2013 15:24 pm

I'm going to go 1x10 on the Scandal I'm building. I'm going to run a 32t e-13 Guide-ring, with a bashguard on Deore M590 Cranks on a Hollowtech II Bottom Bracket. The frame doesn't have ISCG tabs.

Will a Superstar Plasma chain device work OK with this, I guess just replacing one of the BB spacers?

Alternatively if I run a Shadow+ rear mech (I'm planning to, whichever type of device I go for) do you think I could get away with just a seat tube mount chainguide?

Thanks in advance.

That superstar thing should in theory work. It just replaces a driveside spacer. A shadow plus would almost certainly remove the need for a bottom guide.

I might just try the top guide then with a Shadow+; if it doesn't work I can always get one with a bottom guide later as the top one is relatively cheap.

You're better off getting something with an actual BB mount backplate (as opposed to ISCG with a BB adaptor) as the ones with adaptors can be a pain to set up right as it really messes up your chain line. I've been down this route a few times, and I found a gamut guide with a BB mount backplate to work the best, however it's a little more expensive. If you're willing to go without the bash and lower roller, the superstar XCR guide worked fine for me for XC duties, so long as you have a SS ring on there like the guide ring. No dropped chains at all once it was set up right, fine for even fairly bumpy stuff I found. One thing you might find though is that you may have to grind off the granny ring tabs of the cranks to get it to work properly, particularly on an ISCG guide, you may not need to on a BB mount guide.

Lol, you replied before I got a chance - yeah with a shadow plus mech and either the seat tube mount or BB mount top-only guide should work fine :)

Or you could go stealth and use an inner guide ring like the Raidium or BBG ones (or my homemade one, see link in my sig to my Kraken) or using something like an N-gear jump stop.

A Bottom guide is also needed when back pedaling, so a shadow+ wouldn't help with that.....

Not in my experience, my zee mech combined with an e13 xcx guide has been perfect so far, with zero dropped chains and no issues. It's a great setup and had it not been for the lower effective bb on the HD I'd run the same guide with my xtr plus mech too, but I like the taco to give me some bash protection. If you can do without a bash guard, a simple top guide an shadow plus mech is all you need IMO.

I have been looking at the Zee mechs. Cheaper than SLX (or XT) and with a shorter cage; they look a good buy.

Mine has been spot on so far, and given it costs less than a third of xtr, it's nearly as good, not as smooth and a fair chunk heavier, but functionally it's damn near as good. A proper bargain!

I've just ordered the Zee Mech from JE James. I'm looking forward to getting all this together now.

Even without a clutch mech mine was fine for months. With all due respect, the beginner doesn't really know what he's talking about most of the time, a trait to which his title seems to allude ;)

Funnily the last person thatsaid that, a week later told me he'd dropped his chain 3 times when back pedaling for various reasons, but if it works for you, that's fine!

As for ILD - don't think so.....

Then your mate didn't have it set up right.

I've decided to give the Raidum a go, just as it looks like the neatest solution (although I imagine cleaning the remaining chainring inbetween a bash and the raidium may be a bit of a pain in the backside). I'll see how I get on and report back.

I have a homemade version of the Raidium fitted, not tried it in anger yet, but the first quick test ride was all good!

I saw that on your thread in the Your Mountain Bikes section. You should start making those.

LOL, cost me £11.40 and about 30 minutes of time, really really not hard, solid bench to work on, jigsaw with a fine tooth blade and a drill with pilot and 8mm bits.

Anyone tried the Raidium (or BBG) on a 34t chainring? It's only specced to cope with 32t but I fancy giving it a go. Or maybe I should make my own bodge solution instead... that looks reasonably possible for me to achieve if I can get hold of the material.

Got that off ebay.....you need to measure the diameter of the OUTSIDE of the chain around a 32T and then add about 5mm and that should work.

Mine is 146mm and is sized for a 32T.

Yeah I followed your link, although the bloke isn't selling any just now and the other brand you mentioned don't seem to have anything suitable online. But I'm sure I'll find some somewhere.

Could I not just measure the diameter of the outside of the chain around a 34T though?
