I've decided to go from my 36/46 chainrings to a single 38 tooth rotor q ring. I've wanted to try out 1x10 and q rings for a while, I figured I'd do both at once. I have an n gear jump stop to use on the inside. What would you recommend for the outside? Would I be fine just using my old 46 tooth chainring as a guard? Should I get one of those BBG bashguards? If so, what size?

Thanks everybody

Me, I use a 46t on the outside so that I can also have a double ring set-up for my commutes. I have two separate chains sized accordingly: 38t and 46t/38t. I switch out chains for races/commuting.

Nice switch, I'm using a single 39 q-ring on my bike

I run a 40t rotor ring. I started with an N-gear but had my chain come off too often so I switched to dual 42t carbon guards. Also the thinnest BBG's will bend if you hit a barrier hard. If you find that 40t guards keep your chain on I'd like to know.

I run a 42t Rotor with a N Jump and a FSA carbon outer guard.
I think I'm going to go to a 40t...age is taking a toll on the legs :^(
Never had it come off in many seasons.
If you have you chain length correct...your chain shouldn't come off.

Am in the same boat, currently run a 38/46 Q-ring set up.
Going to try just the single 38 with one of these:

Use a similar setup on the MTB and it works like a dream.

Will post images once done

I ran a sinlge for a year and went back to the double. I found the single was good for about 1/5 of the courses i rode.

I run q rings and really can't picture going back. But when i ran a single it was a reg. ring. A single q ring set up would be intresting. I would go 42 at the smallest. With the new 11-28 cassettes there is nothing that you could not handle. If it is too hard for a 42-28 then it is faster to run anyways.
