The Oregon Outback was the testing ground for this bike. As a prototype it was ridden with a rattle-can clear coat to give basic rust protection, so that additions and modifications would be possible. After going the distance and tweaking the design, we have here the finished product. Just back from the powder coater, this is a fresh finish on a bike that has gone the distance, seen the dirt, passed the test and now it's time to give it a home. First the specs, then the details.

Parts List:

This bike has fewer than 1000 miles on it, and the parts on it have been used at least that much. Some parts are brand new since the bike was powder coated, and some were used before being put on the bike. Either case will be noted. All the parts are in excellent working order, and have many miles and years of life remaining in them.

Thoughts and Ideas:

This bicycle is the culmination of many years of building touring bikes, trying them out, refining the ideas, re-building them, and again and so forth. I've experimented with weight distribution, wheel and tire size, geometry, particularly the front end geometry, looking for that balance and sweet spot between handling and load bearing. There are merits to many different styles, and in the end I believe that personal preference is the final decider. That's why there is not one, final, end-all style touring bike that everyone emulates. We all tour with different stuff and want to go to different places, covering all sorts of terrain.

The Outback 650b is my most recent revision of the touring genre, and I like it on most every level. It's built to go just about anywhere, it climbs well, feels good on the long flat stretches, handles well through corners, both loaded and without. The riding position is comfortable for many hours of saddle time. I like the way the weight is carried and how it feels when loaded. And, for me it's also important to have a bike that will serve me on a day-to-day basis for year-round commuting, which this bike does. Also, the aesthetic, with the simplicity of Henry James lugs, the threaded steerer and quill stem, the standard oversize tubing and the fat tires -- it reminds me of early mountain bikes, but with top quality parts for functionality and durability. I feel like this bike strikes a great balance between aesthetic and function. It's going to serve someone well for a lifetime.
