Double carbon guards at scouters. No problems.

metal chain guide
Schreck, George
2005-10-24
I have double ring guards, and despite some particularly pathetic riding
on my part, I cannot blame my poor results on dropping a chain. I wish
I could, as it requires that I confront my ineptitude. Not something I
would wish on any man or woman.

Subject: RE: [OBRA Chat] metal chain guide
Regarding single ring setup on cross bikes... I have since changed my
mind after last weekend's race at Scouter's Mtn. Considering that I got
my chain stuck twice underneath my N-Gear metal chain watcher, I would
have to recommend the plastic "3rd Eye" version. The metal one I think
is a bit too flexy, which on one hand, enables you to bend it away to
get the chain back up so you can continue, but on the other hand, didn't
seem to keep the chain on as well to begin with, nor after I bent it.
I think the "double chain guards" method would have been best for
yesterday's super choppy grass sections but we were comparing the two
other options w/ this discussion. I'm sure lot's of people had issues w/
chain drop yesterday. Anyone have it w/ double ring guards?
Keep the rubber side down,

Hi Jason,
I have two bikes and one of each chain guard you inquire about...
Plastic one and Metal. I have no preference for one being better than
other. As the plastic one wears over time if it is too close and rubs on
chain, it can get more flexible and a chain can get jammed down. You
want to position the guards as close as possible to chain w/o rubbing
against the chain/ring in the big cog during crank flex.
I haven't had a chain jam for at least 4 years using the setup (knock on
wood). It did happen once a while back on me due to plastic flex. I was
stuck w/ it caught below. Game over.
I have since learned that it isn't the part's fault, more my fault. I
have managed to avoid it by monitoring my chain situation prior to any
bumpy dismounts so the chain isn't in a slack or sketchy state on the
rings or cogs. I do so by shifting early before barriers and confirming
good chain status by soft pedalling a couple times before the barrier. I
also pay particular attention to my remount and not force it in any way
if it isn't clean on the rings. If you develop good habits, you're less
likely to get the chain drop. Be careful setting your bike back down
too. As the boys in pink/red say, be "gentle".
Good luck.
Chris

I run double chain guards; no drops at Scouter's. I know of at least one
rider who had several drops with a third eye. That course was *mean*!
Cheers,

It is the N-Gear jump stop. See http://www.gvtc.com/~ngear/. Works great,
much better than the Third Eye. I have a few extras if you want to buy one.
Let me know and I will look at the size.

Jason,
I think you're looking for an "N-Gear Jumpstop"...

I saw this the other day

Basically a plastic grooved roller mounted right where the chain comes
unto the chain ring. Looks simple.

I think he is talking about the front chain ring. I believe the Surly
product is to run a single speed in the rear.

Both can flex. I have had to break both types during a race to get my
chain out. If you are running a single ring, put the single ring on the
outside of the spider, and put a guide ring on the inside where the
little ring used to be. Put another guide ring on the outside of the
single ring using spacers and longer chain ring bolts, and you will not
have any problems. FSA makes carbon guide rings and Salsa makes
aluminum versions. River City usually has them in stock, along with the
spacers and longer bolts. In fact they have a bike on the floor with
that set up.
