    Odd numbered 104bcd front rings

    Everywhere seems to just do the even n/w rings these days.

    Anyone know manufactures apart from renthal that still make resonably priced odd tooth rings.

    Im looking specifically for 33t.

    Endless Bikes makes a 104 BCD in a 33 tooth. Endless Bike Company | The Odd 1 Chainring

    It's not cheap, but you can get lotsa blingy colors, and Shanna, who owns Endless, is hella awesome.

    Surly. I ran 33x15 on my MUSS back when it had 26er wheels.
    I don't know why,... it's just MUSS easier to pedal than the other ones.

    Ta, I have an extra 33t 104 Surly in my parts bin. It's used, but has plenty of life left. Shoot me a PM if you're interested.

    Otherwise, I'd second the Endless Bike recommendation.

    I have a 33t and 35t Singlespeed rings for 104BCD. My current SS use cinch cranks so they are of no use to me.

    Someday someone is going to come up with a front ring that will have 66 NW teeth and a 2-1 planetary gear so it can be both effectively 33t and NW at the same time

    Probably. They have some oddball rings. They were the only current source for a 34/110 I could find.

    any benefit to odd over even? or is it simply a matter of finding the perfect ratio?

    ^it's a combination of finding the perfect gear ratio and what fits best on your bike. some combos will force you to move the axle in a sub-optimal position for your preferences, so finding the combo that allows you to put your axle in the right place to get the effective chainstay length you want might be needed.

    for example, I could run a 34/21 gear or a 32/20. I chose the 32/20 because it puts my axle further forward on my bike, shortening the chainstay length, which I prefer.

    to get an idea of the effective CSL you can get from different combos, check this out: http://eehouse.org/fixin/formfmu.php

    Yea. This.

    For me it was finding the point that I could properly tension the chain with the axle where I wanted it. 34x20 wasnt right but neither was 32x20 so I went with 33x20. Yea I could have changed the rear cog to make it easier but I had a nice absolute black NW rear cog I wanted to use.

    It's not that bad actually. Really nicely made parts though.
