Chain guide advice

JayKingFunk

I'm looking at getting a chain guide.

I want to convert my bike to a 1 x 9 set up as I never use the top or bottom rings.

I'm thinking of getting a bash ring to protect the middle ring but am unsure what chain guide to get that leaves room for a 2 ring set up.

I've been looking at the Truvativ Team BoxGuide but not really sure if it will fit with 2 rings.

Anybody else done a set up like this?

Thanks in advance, J.

i'm fairly sure most allow you to use a bash guard

Sir HC

The top roller/guide on a chaindevice is the most important part. On a double ring setup, the mech does this job.

I'd have a look at the E-Thirteen XCX and the MRP X1, much lighter than conventional chain guides.

thanks for that.

So basically I need to go for one with a top roller if I'm ditching my front mech?

I've seen some with top guide and a bottom roller, does anyone know what the bottom roller adds? Is it just for tension??

Cheers, J.

just for extra chain-retaining ability

i use a n-gear jump stop, to stop the chain from jumping to the inside. and FSA bashguard on the out side.

not been running it that long, but no probs so far.

just make sure you have a non-ramped, no pins - single speed specific (that accepts a 9 speed chain) chainring.

i use this for XC mostly, and tame downhill.

I don't see why, if your chain retention system is doing it's job, then it shouldn't make a difference.

So does it have to be a specific chainring then if I only want to run one up front?

I was planning on just removing the chain rings that I don't use.

Saying that I'm still undecided about having one ring up front or keeping 2 but I like the idea of ditching the front mech and shifter 2!

It doesn't need to be a specific ring. I just took the inner and outers off my deore set and shortened the chain to help stop it falling off. I changed recently to a Blackspire SS specific one that I had spare but the chain still fell off at the most annoying time at high speed going over bumpy ground, confusingly this is something that didn't happen with a SS set up and tensioner.

As a result I'm waiting for a MRP 1.x to turn up and see if this helps. Didn't want to go for the roller option as I there's no ISCG mounts on the frame and it all looks a bit industrial for XC anyway.

That's because there's a lot of slack still because the derailleur bounces around, whereas on a SS bike with a tensioner, there's no slack for the chain to bounce about and fall off, hence why you don't need a chain guide on a SS setup. If you're going 1x9 on a MTB you at least need a top guide, though the chain can still come off occasionally, hence why i have a chain guide with both top and bottom (and you can get a BB adaptor for the ISCG tabs by the way)
