1992 Bridgestone XO-1
Part Diary, Part Technical Manual, Part Tips & Tricks

Never paid attention to Bridgestone bicycles. I was aware they existed, but they never interested me. Early in 2007, I was reading about bicycles online and came across an article on the XO-1. After a little bit of research, I was very intrigued, by the cult status of the bike and the philosophy of Grant Petersen. So I started looking for one online, hopefully a 52mm or 55mm frame in Pearl Tusk (1992) or Construction Pumpkin (1993). So I search for a bit without much luck, so I try something that I've never done before, I posted a WTB ad on craigslist. I posted the ad on March 28, 2007 with no response, BUT on April 1, 2007, a person in San Francisco posted an ad for a 1992 XO-1, 55mm, all original, in Pearl Tusk! So I drive over the following night and brought my baby home. The XO-1 has turned out to be an excellent bike. The steel frame feels fantastic and climbs very well, especially considering its weight. I probably ride this bike more than any other bike.

4/9/2011 - After four years, I sold the bike on eBay to a person in Montana. I'll probably miss the bike, but then again I always do.

The following is the summary of the components, using as much of the original parts as possible:

Saddle: Selle An-Atomica Titanico LD. I got the Selle An-Atomica in March 2007 and haven't put too many miles on it yet, but I've noticed a great improvement in comfort since the very first ride. The saddle also looks period correct and very BOBish. Its perfect for those 50-60 mile fundraiser rides that I enjoy. At this point in my life, I'm less concerned about counting grams and much more concerned about my comfort and health.

The bike currently weighs 25lbs 11oz as shown.
