    Newbie Ratio Help Question Pls

    I am ordering a cog for a new setup and figured I would get a 17t cog for the new 48 chainring. Now I currently ride a 40/15 which works out to 70.1 gear inches/3 patches and it works fine . I used to ride 40/14 which was 75.1 inches and I am much happier now.

    48/17 is 74.2 gear inches but has 17 skid patches. 48/18 is 70.1 but only has three patches. I am wondering if I would be smarter to go with an 18t cog despite the lower number of skid patches or just suck it up with the few extra inches? Anyone made the small switch from 48/17 to 48/18 or viceversa? Should I even worry?

    What say you?

    You could always just go down on the crank size and keep a 17t rear cog.

    I've had my Fuji Track for less than 2 weeks. Rode stock 48/16, brakeless. Bought a 17t, and a front brake. I've since removed the 17t and put a 18t on. Since I find myself skidding/skipping, I may go back to the 17t for the skid patches. For comparison, I rode 40/16 on my fixed conversion. Cogs are easier to swap.
