    Gearing question

    I've been riding 42/15 (170mm crank) for god knows how long. I think that is like 75 gear inches / 2.8 gear ratio. I don't skid all that much, so I'm not overly concerned with maxing out skid patches (that said, more is always better).

    So, assuming I wanted to keep same gear inches / ratio, and was not just looking to increase skid patches, what substantive difference would I experience if I switched to 48/17, 51/18, etc? Stated another way, if someone was not just looking to increase skid patches, why would they choose gearing X over gearing Y when they both have the same gear inches / ratios?

    Thanks in advance!

    It's my extremely limitted undestanding that smaller cogs wear faster. Other than that and skid patches, it makes no difference.

    Sheldon Says...

    For a more shallow answer - find the front ring that looks best, then determine the rear. Depending on the crankset, certain rings are more available, cheaper, and more aesthetically pleasing. I don't love small rings on bid spiders.
