Is anyone running a 1x9 setup w/ a front ring < 42?(8 posts)

Is anyone running a 1x9 setup w/ a front ring < 42?D_man
Nov 9, 2003 8:54 AM
I was thinking of converting my CX bike to a 1x9 setup (with the primary applications being singletrack and fireroads), replacing the big ring with a bashguard. The only 130bcd rings and bashguards I've seen out there with this setup in mind are 42 and 44, and I'd prefer to run something smaller, maybe 38 to 40. Do smaller rings/bashguards exist?

As an alternative, I guess I could just leave my current 39t innnerring on and replace the current outerring w/ a 42t bashguard. Not as clean looking, but it should work, right?
Here's some porn to accompany my long questionD_man

I run a 44 chainring with a 11-32 XT cassette without a bashgaurd. If you don't do much bunny-hopping or can bunny-hop well there is not much use for a bash ring, save, perhaps, to keep the chain from falling off to the outside. To remedy that I keep my front derailleur on and move it down just a bit so it straddles the chainring without interefering.

I was thinking of converting my SS to a 1 x 9 and wanted to do it cheapest way possible-I don't race so I want to keep costs down. I thought that keeping the f derailer on w/out shifting would keep the chain in place, but wasn't sure. Now I know it can be done-thanks.

I am using an XTR ft derailleur and the outer limit screw is not long enough to lock out the outside swing of the derailleur if the chainring is in the middle position. I solved this by robbing a longer screw from an LX der in the junk parts bin. I also left my front shifter on so I can still trim the derailleur since a 9sp cassette still has fairly wide chain angles. You may be able to do without the shifter by bending the derailleur or inserting a spacer in the screw holding the derailleur cage together (but not all derailleurs have that screw- my top swing XTR does, my older bottom swing XTR doesn't).
I plan on using a road derailer. nmKG 361

I have a DA crank with a 39,42 and 44 front chainring and a Wetzikon chainring gaurd (bashgaurd) and an 12-25 for racing and a 12-27 for training with. Works great for CO but my cross bike is strictly a training and race rig.

Good luck with your decision

but have settled on a 39/42 front setup with a der. It isn't worth the hassle to keep the chain on the ring and the inability to get it back on in a race. I use the 42 exclusively but can "hide" the chain on the 39 for bunny-hopping or any situation that might damage the chain.

The only problem is the fear of impalement by the outer ring rather than the smooth lines of a bashguard, but that's why we run on the non-drive side...
