BIKE SHOP GIVES WRONG SEATPOST SIZE

September 14, 2005

    What is the size of the seatpost on a '98 diamondback Mr. Lucky? Is it 22.2 or 25.4? It has 25.4 stamped on it but the guy at the bike shop said it is 7/8. Which one is it? I need to order the post on-line and I don't know which to get.
    By the way, it is so cool that you help people for free like this.

John:
    I’ve got the answer to the question you asked, but not the one you didn’t ask: Why did the shop guy refute the size stamped on your seatpost? Did he put a sizing rod into the seat tube? Or did he instead use his pipeline—the direct one he has to an advanced alien intelligence? Perhaps he exists simultaneously in a differently-scaled parallel universe?
    Anyway. Diamondback spec’ed that bike with a pillar-style (without an integrated clamp), chromoly 25.4 mm seatpost (about one inch diameter)—not a 22.2 mm (7/8"). Accept no substitutes.
    More free advice: If you wanna support my work you can buy my book, Urban Bikers' Tricks & Tips. Already have it? Makes a great Xmas gift.
