Fork number six was made to replace a stock fork on a Trek 520. For the 520 fans out there who probably aren't following this blog, it is one of the elusive non-green 520's that this fork was made for. There was barely enough room to run a 32mm tire and fender on the existing unicrown. (Unicrown construction really limits tire clearance in this application.) By switching to a lugged crown and adding 5mm of axle-to-crown distance, there is now room for a 52mm tire and fender. The only other detail changed was adding fender mounts to the inside of the fork legs so the rack and fender wouldn't have to share an eyelet anymore.
Number six will soon be able to "see Russia" from it's temporary home in Alaska with this guy.
