Pure Cycles Original - smaller chain ring?
Just picked up a four year old, lightly used Pure Cycles Romeo with a 44T chainring. The chainring is five bolt pattern...
I hope to commute to work on it and realize that a fixie exists to humble a guy used to gears... But I wonder if there's Is a smaller chain ring I can buy to make climbing hills on this bike a little easier?
Thanks!

Are you already maxed out on the rear sprocket, or are you using the usual 16 tooth?
I always try changing ratios with the rear sprocket first. Going up to 18, 19, or 20 teeth ought to get you what you want.
Edit: Just noticed this thread is from June 20, yet it popped up as the newest thread in my internet browser. Something flaky going on?

No worries. I received advice from the manufacturer to change the free wheel rather than the chain ring. I did so - going to a 20T rear gear and have ridden it a few times back and forth to work. Hills are manageable now where with the 16T rear gear they would not have been.

For anyone else who wants to lower the gear ratio on their Amazon special fixie:
I have (am borrowing from my wife) the same "pure fix" bike and am modifying it for tricks. I switched the 16t fixed cog to an All City 22t track cog which makes it 44t/22t. Decent combo. I also bought a Gebhardt 38t chainring for the 130BCD cranks that come standard on the bike. I don't recommend this. 38t is the ABSOLUTE smallest chainring you can deal with in this size. I should actually file down the spider on the drive-side crank. the 39t from All City is a good example of a chainring that should avoid this problem while still getting a low(er) gear ratio (39t/22t). Waiting for a 25t coming from Taiwan.
