You still have not answered the question. A 19T cog is not really a track cog in the first place.... why not just toss on a 17--- assuming it isn't welded on.
dude. whoa. how did you know I was running a 48T currently? your physic abilities are fantastic!
that being said, my old gearing was 53X19. but I completely replaced my crankset and now run a 48X19. it spins out far too quickly. therefore its imperative that a larger chainring be in the immediate future.
cheap! neat looking (the beaver logo is cute). but how does it ride. I have never even heard about blackspire until you posted it friend. may you offer some review and/or opinion of them?
thank you all for the help, friends!
