Hi all,

I'm looking to convert my two ring Kona Scrap into a one ring with a light weight chain guide... Any good products you guys suggest? I don't do any heavy bashing on a regular basis. When I try to do 180's the chain comes off sometimes, jumps - sometimes too. So, I need something that'll keep the chain on and not weigh down my already heavy bike! Thanks!:thumbsup:

I'm a big fan of the N-Gear JumpStop, and an outboard guide ring, (lighter than a bash guard) like the Spot.

Jump stop: (comes in three sizes, 1 1/8, 1 1/4, and 1 3/8")

Spot ring guard:

For the ring guard, I've also made my own out of thin polycarbonate, with good results, and I've seen the BBG's mentioned lately but haven't used them myself:

Finally, I have a custom cut ring coming from Mattias Hellore (he's posted about water-jet cut chainrings on this forum) which should be *very* light.

Cool! I'll check it out!:thumbsup:

The jump stop looks good for the little ring - stop chain from falling off....cool.

I'm looking for a 1 x 9 single ring up front light weight chain retainer / guide...

Any other good ones?

The Jumpstop works for a 1x9 setup.

But if you want a full guide... The Gamuts are pretty light and the new e13 will be very light.

Yeah, fmf mentioned "jumping" and 180s in his first email -- those are probably far better choices as I don't know that a Jumpstop and guide ring would keep things in place.

I used to run the MRP G2 but this season I went to the new Gamut guides on both my Cannondale and Foes and I love them. They are light, easy to setup and just got lighter as the poly guard has lost some weight and new nylon bolts for the upper guide replaced the stainless steel bolts.

I second the Stinger guide suggestion. Add a bash and the Jump Stop if you really want, and it's still lighter and cheaper than the "full" guides out there.

If you do not require the protection of a bashguard, what you want is a Rohloff upper chain guide. It's spendy for what it is but it is a pretty perfect solution for xc 1x9. I run it on my turner which drops chain off the top from chain growth when I hit square bumps. My hardtail needs nothing to run the 1x9 with the 34t ring up front but I use the Jump Stop with the 32t ring.

When running a 1x9 setup, be sure to use a singlespeed ring up front, not one ramped and pinned for shifting.

Hey fmf,
You should be able to scoop up an LG1 a little bit cheaper now, as well. A lot of places are trying to make room for our 2009 chain guides.

Also, all of our single ring guides come with a bottom bracket mount adapter, that you'll need to install on your Kona.

Happy holidays!

Look for the guide Rohloff offers ..... that one's pretty light.

I shortened the cage for my 32t setup and that made it even lighter.

If you are not extremely aggresive, a short cage derialler (holds chain tighter), bashguard and ngear will do really well, that is what i run and it works for me. YMMV

because of where the pivot is on my gary fisher hifi, i cant run a traditional seat tube anchored guide. i drop my chain at least once a ride and it blows!

I think if you can run a front derailleur you can run the Rohloff guide as it's more or less the same thing.

Worst case scenario you can sandwich it between two bashguard plates. Blackspire makes an inner guide plate which you use with an outer bashguard and that works well also.

Sorry for the thread resurrection, but I was doing a search for lightweight chain guides. I stumbled upon one from Helium Components. Helium Components - Lightweight mountain biking solutions. Probably wouldn't work for the jumping crowd, but for the XC crowd, it seems like a nice lightweight setup.
That one will not work on a lot of carbon frames, you can't get the clamp low enough because of the taper between the downtube and seattube.
