Over the weekend I traded my chrome italian fixie (sold on the local craigslist) for a used il Pompino (bought from my friend steve). The picture above is taken on the first hilly ride after the build. I will elaborate on the whole story a little later. For now, here is the build list:

- on-one il-pompino frameset; on-one designed tubing, wish-bone seat-stays, 135mm drop-out, semi-compact geometry; 54cm seat-tube (though it fits like a 56 or 57cm); high bottom bracket shell. My friend Steve bought it used, and actually had bernie Mikkelsen brazed on some bits for him (derailleur hanger, downtube cable stops) and rode it as his trail-bike/commuter for a while. He has a soma doublecross now and decided to sell it for a good price. I won't bother taking the braze-ons off
