what to prevent a 1X8 from throwing the chain off the ring(11 posts)

what to prevent a 1X8 from throwing the chain off the ringctisevn

I just set my cx'er up as a 1X8. the single speed conversion will have to wait. Ive had no problems yet. It seems like I should do something to keep the chain on the ring up front though. what are my options besides the $150 kit that cyclocrossworld.com sells. Ive got a deore crank with a 42t ring. Should I just pick up a salsa chainring guard and leave it at that or should I get a non ramped ring etc...anything else I can do? should I do anything at all? the bikes mostly just a sloppy condition road bike but Id like to be able to take it on some trails without stressing about the chain dropping.

I'm a lurker on here, a newbie, and the answers to this question were to get a 3rd eye chain ring thingy as well as well as a guard. But you get an old chainring slightly larger than your 42 and grind off the teeth.

BTW i just bought my first cross frame off of ebay today, im excited.

Check out the jump stop. Works much better than the third eye.

looks like a simple, cheap solution. have you used it with a single ring setup?

I'd highly recommend the Jump Stop. Inexpensive and nicely made. I use this setup on my 1x8 MTB, and I wouldn't change a thing.

Yep, I have it on a 1x8 as well. The cool thing about the jump stop is that the plate can extend quite far. The third eye can only reach so far, and works better for geared setups than single chainrings. Email the guy and he'll send you one before you even pay him. If you like it then you send payment. Amazing.

thanks for the input, I emailed the jump stop guy. I think Ill pick up a 42t ring and use my 44t as a chain guard too.

Rohloff makes 14 speed internally geared hubs, along with other related products such as this:

I guarantee the chain will never come off if you install that thing.

Makes me want to change to a single chainring just so I can have one. That is one nice looking guide.

and also with a 42t ring. My uncle, a belgian shop owner tells me to lose it as the rigs should be big enough to hold the chain, guess I'll keep it on anyway.
My Rohloff guide is tweeked a little, some extra rings to open up the cage, allow more chainspread. It rubs a little in the largest and smallest gears, but not a problem really, just a cool rattling sound. Room for improvement, will make sure I'm rub-free by next winter. So far, in two short seasons of various races, regional to super Prestige and Nationals, my guide never developped any problems in terms of throwing chains. Some rattling, but the trust that it'll always still on is worth something. Oh, this guide is solid and light, 70g stock and room for shaving :-)

Thanks PURTY! I just have an old derailleur locked into place and bent down low over the rings. Same theory, MUCH uglier.
