I am in the process of setting up a cheap 1x9. I am using a XT long rear derailer, 9 speed 11x34 cassette, Shimano Deora cranks with the small and large sprockets removed. I really want to try and use nothing on the front, has anyone tried this? Did your chain stay on, skip ect?

Can you get away with out the FD if you use a SS type chainring in the front?
It may help a little, but no, you will still likely loose your chain a bit on the trails. A BBG Bashguard and n-gear jumpstop will run you about $30, including shipping. I have used this setup on a hardtail for the past year (no big drops or jumps) and have never lost a chain.

I went 1 X 9 with a long rear der and a 22 up front. I found that I would jam the chain in between my small ring and the BBG bash guard. So what I did was took an old middle ring and ground it round, and then attached it. It acts like a chain guard keeping the chain from jamming, and a bash guard. It also gives you more clearance than a larger bash guard, a bit lighter and no cost at all!
I ride very rocky terrain, and have not lost the chain but once in the last 5 rides. I took one more link out of the chain, so I guess that helped. I took off the front derailluer and shifter too.
Good luck!

22t ring? Don't you spin out pretty easily with that?

Nope. But I sit 99% of the time on climbs. One guy I know has a 20T granny.

I realize it is fine for climbs, but what about on the flats or pointing down? Assuming you have an 11t cog, 22:11 is not a very high gearing. I've run that ratio (2:1) on a single speed, and you spin out pretty easily as soon as things are even slightly downhill.

Am I correct in assuming you are using the 22t ring in the small ring position? If so, you are doing some real cross chaining in the highest few cogs. Also, how did you run the BBG bash? In the middle ring position or the big ring position?

Your friend has a 20t as his only front ring?
