Best bike chain deflectors according to redditors

OP, your chain is fine. Check out this tech tuesday article, you'll see your rear mech looks pretty much identical

You need to add an N-Gear Jump Stop, it will completely stop your chain from bouncing off. I run my 1x setup with tight chain and n-gear, never drop a chain.

Judging by your chain rings, this is an older bike. In the past few years, chain stops have been introduced to prevent this from happening. I use one (N-Gear) and have had very few problems since it was installed. The newer ones (if they are more carefully adjusted) may even work better. Links to three chain stoppers on Amazon are provided below. Your local bike shop may also be able to help. Adjusting your stops on your front derailleur to its most conservative setting (that still works) will help.

Had the same issue with a DB Hook. If it’s that cheap plastic piece above and below your chain ring, don’t bother with their chain guides, get a proper narrow wide chain ring and if you really want to, there’s this guide on amazon.

Raceface makes a relatively cheap, well made narrow-wide chain ring.

i've got a franken-gravel bike that's like this - i took the big chainring off and put the small one on the outermost side of the crank (where the big one was) to help keep the chain line straight.

if you can manage to find a 'narrow-wide' chain ring - it's a solid investment, helps to keep the chain on.

I don't have a front der, so I used this (https://www.amazon.com/Origin8-Torqlite-UL-Chain-Guide/dp/B008ZTLV9W/ref=pd_rhf_ee_s_rp_c_0_9?_encoding=UTF8&pd_rd_i=B008ZTLV9W&pd_rd_r=2b612691-9413-4481-b9a3-7bdbcd0d8d19&pd_rd_w=Gk3jV&pd_rd_wg=9HtN6&pf_rd_p=87f46b45-938f-430f-a8e4-ecf1b1b39902&pf_rd_r=4H18PQ2X8TQ7MSQ0KK85&psc=1&refRID=4H18PQ2X8TQ7MSQ0KK85) in conjunction with the narrow-wide ring to keep the chain from bouncing off

it's a great idea - consider a mountain bike cassette and a small chainring to help you with the climbs. The big thing I have to deal with is not shifting under load, when the chain comes off - it's off. Without the front der. there's nothing to help you get the chain back on the ring without stopping and doing it with your hands

Yeah it will change gears fine, just mount your front ring with good chainline.

A chain catcher like this: http://www.amazon.com/N-Gear-Jump-Chain-Guide-Watcher/dp/B001CJXEKG/ref=sr_1_1?ie=UTF8&qid=1414128685&sr=8-1&keywords=chain+watcher will add extra security cheaply.

Or a cheaper chain guide like this one..

A little late to this thread, but on my 29er I had the same sort of issue with the chain coming off. Total pain in the ass. I installed a chain guide courtesy of Amazon and it hasn't fallen off since when having to shift to those lower gears. Good luck!

I don't run any kind of chainguide for the riding I do, which is either fast and flowy or technical (roots errywhere) XC, with the occasional drop/jump.

My entire reason for going shadow+ was to quiet the bike up. Before replacing the derailleur and going 1x10, coming down a rooty section sounded like a toolbox falling down a flight of stairs, and that's with serious chainstay padding.

The only thing I hear anymore is the very occasional slap and every now and then some rub on the RF bash I have mounted up. I use the bash and a JumpStop to keep the chain on, I've had one chain drop since going to this setup, and that was in a wipeout.

If you're getting a clutch derailleur AND the upper guide/bash, I wouldn't sweat the ring. You really have to work to throw a chain from the bottom with the new mechs. The tension is adjustable, too, you can always crank it up or down if shifting gets too hard or you keep dropping chains.

I ran my KM 1x9. I liked it but I had a lot of problems with chains exploding. I used a Truvativ Stylo 1.1 crank with an XTR rear derailleur. Hooked it up, aligned that track drop and ran it. I used a jump stop to prevent dropping my chain and a chaingaurd on the outside. Worked pretty well, but I never could dial it in just right. I run a 2x9 now and it works great.

This might work. It’s not a chain guard, but will keep the chain on.

Oh hey, I was in the same boat. I swapped over to 1x from 3x at the front and my chain would fall off the front ring in rough sections. I tossed one of these on the front https://www.amazon.com/Origin8-Torqlite-Chain-Guide-31-8-34-9mm/dp/B008ZTLV9W?ref_=fsclp_pl_dp_2 , and once I got it set up super close to the chagrining it did its job. No more issues with the chain popping off, and cheaper than a new derailer with a clutch.

Wait...I think I used the wrong term. The chainguard you refer to, I'm thinking, is the plastic disc, about the size of the chainwheel.

I meant to say a chain guide. Like this. As far as I know the BBS02 comes with a chainring chainguard but does not come with a chain guide.

If the remaining chainring is a ramped one with ramps to make the chain shift easier, you might need something to keep it on. Since you already have a bashguard you can put one of these dog tooth things on the other side. https://www.amazon.com/Origin8-Origiin8-Chain-Deflector-Black/dp/B07BZP91ZL
