Chainring specs defined
Hello all,
I'm currently trying to figure out and better identify what I need and what is being said when I see, "chainring 144bcd". I've seen other figures too. Can someone either explain what the numbers mean or have a link you can provide?
BTW, I have a 50/34 crankset and I want to get something a little lower in gearing. I have a 700c bike and would like something leaning a bit more towards climbing. I don't even know if I can put anything smaller than a 34 tooth ring on. Having a 30t or a 32t would be what I'm more interested in. Even the large one can be down to 48t.
Any help on this is very greatly appreciated and most welcomed.
Thank you,
