chainring bcd
 

so, the bike I have, I didn't build up myself. It's 110bcd... I think. I measured 65mm but looked at Sheldon Brown and it's probably 64.7. I was just trying to eyeball it with a metric tape measure. while still on the bike. Is a 110bcd chainring weird? Probanbly not for a conversion but is it uncommon? what do you guys have?
I'm just planning on buying different generic chainrings on ebay to get something comfortable for me. So far, I have found some Salsa rings with a 110bcd. Tonight I'll probably be going to down to a local bike nonprofit and I'll compare rings and ask them about it.

110 bcd is not too weird. BMX uses it so you can always find BMX chainrings. You can also buy chainrings at loosescrews.com in that size.

bmx and older touring doubles and modern compact cranksets (big big ring, small little ring) all use 110. not weird or uncommon.

a decent low cost ring for it would be a rocket ring. has holes for 110 and 130. run you about 20 bucks.

110 is one of the most common BCD's you can get. There are road rings, mountain rings, and BMX rings that are this size. 32t is as low as you will find, and 53t is the top limit (AFAIK).

I have a 56 tooth ring in 110. Its for a downhill mtb.

'kay.
thread done.

Plus there used to be 110 track rings in 1/8, have one in 50T

Take a photo, that sounds awesome.

*edit - 58 tooth!!!
