Big Rings

Any recommendation for relatively inexpensive (~$30-$40) 44 or 46 tooth outer rings for a compact 110BCD 5-bolt crankset? I was looking at the FSA 46T rings for ~$40.

Also, it looks like 44T is not common for "road" chainrings, so if I wanted to run a 44T, is there is any problem using "MTB" chainrings on my "road" cranks. Assuming the BCD/bolts are the same, would they fit/function fine?

A good selection of cheap chainrings here:

Looks like they have 44 but not 46. It's not ramped or pinned, so your shifting might be a little sluggish if you've got a really small inner chainring. I've found, though, that with the smaller rings, ramps and pins are not so important.

I have 36/44 (or thereabouts) Sugino rings on my bike, and the shifting is fine (bar-end shifters).

You''ll have no problems running MTB chain rings if you want. A couple of years ago I ran some Race Face ring's 110 BDC that were fine. ALso you might want to look at Nashbar, their stock chainrings are made by stronglight and are very high quality.

I use an XTR 46T as a big ring on my compact crank. Works fine!

Thanks, I was wondering about that too.

Thanks. (So what is the difference anyway, between a road/mtb chainring anyway??)

Yeah, I've looked there, but there stock seems to be spotty/limited.

Well, there really shouldn't be a real difference with Shimano stuff b/c mountain 9spd and road 9spd use the same chains.

Usually the difference is the BCD and that's about it.

I have never found much difference, maybe some of the road ones are a bit lighter...I used to run a 46/36 (Nashbar rings) on a Sugino crank with Sram cassette and chain and whatever shimano read dr I happen to have at the time. Basically I found that it seldom makes a difference.

Thanks, all. Just bought a Ringle 46T mountain chainring from the eBay.
