I own a Diamondback Outlook GX, purchased last year from an NYC store that refurbishes and sells bikes acquired at NYPD auctions. My seat was swiped on the street a few months ago, and when I went looking for a replacement, none of the six or seven bike stores I went to had a seatpost that fit it. I can't find any info about the Outlook GX on the web at all, though info about various model-year Outlooks is pretty easy to find. Finding the exact seatpost size is my top priority (I have a smaller one with a shim to make it fit), but I'd be psyched if anyone could point me toward a detailed spec sheet for the bike. Thanks!
