Newbie Question about cranksets/chainring
Please excuse me as I am pretty new to biking... I tried searching for the answer, however, I didn't have the correct search terms.
So I am in the progress of converting an older sekai bike into a fixed gear and I pretty much have all the parts, however, I am confused about what I need to do with the crankset/chainring.
On my rear wheel I have a 14t 1/8 cog and I would like to run a 34ish tooth chainring in the front, but I am not too sure on how to go about doing this. The crankset that is currently on the bike is setup so that I can't remove the larger chainring (52ish?) without removing the smaller chainring (32t) - see attached pics. What would be the cheapest/best way to go about this? Do I have to buy a whole new crankset? or can I just replace that chainring with another chainring...
Thanks in advance for the help!
