I seem to be amassing bikes as I go. They get replaced and disappear and recently have been showing back up. The Fargo is the first bike I have ever owned that actually makes me think about getting rid of bikes. It's the only bike I've ever owned that I truly feel could be the ONLY bike I own. That would be thinning the heard from 7 to 1. (Or 7.5 to 1.5 if you count the Skate Bike.)- Commuting - paved, dirt road, single track and deep gravel on my 5 mile commute
- Fully loaded touring paved and mild unpaved
- Gravel road exploration
- single-track

Single-Track:
Stable and confident, I was able to take loose off camber corners faster on the Fargo than on my 26" full suspension rig. I also felt a lot more stable in deep gravel both up hill and down. However, with the lower BB I clipped more pedals and the 48t chainring has a couple "custom" shift ramps. The added confidence from the Fargo did translate well back to my 26er.

Commuting/Touring:
With the ability to swap from a 700x32 to a 29x2.3 I was able to change routes and tires to match my mood and any sides trips to and from work. The added stability translated well in the bad weather. I had a lot of trouble with the high rake on the front fork getting the front low-rider rack mounted level. I ended up putting it in backwards to get it close to level. Which worked for a 100 mile touring weekend and for trips to and from work. Also with the low location of the braze-on's on my seat stays there was a lot or distance to cover from the rear of the rear rack to the bolts.
This allowed a slight wobble on the loaded rack at 35mph. 40 turned out to be as fast as I was willing to go. I think a stronger rack, like a Tubus (or the new stuff from Salsa, more later) would not have had this issue, nor a larger sized frame. I think I gave up some efficiency on the road most of the tour, but got a lot back when we turned off the pavement and did less walking, when I caught up.
Gravel:
As a gravel machine it did well with the bigger tires. I have to take a lot of pavement to get to the gravel around here so I started out with the 700x32's. In doing I clipped several rocks with the pedals, granted I ride a larger pedal. However when I switched over to my 29x2.3's and tried the same route, it went much better. I didn't loose as much on the road as I expected and gained a lot more on the gravel.
Conclusion:
I LOVE this bike, did I mention that? Should be enough but for those that don't want to read
all of the above, (in the words of Inigo Montoya) "Lemme sum up".
Fast, stable and confident off road and in bad conditions but low BB height. Great for touring (thank you low BB height.), commuting and all kinds of rides. Getting racks to fit is a challenge but can be over come. Disc brakes allow easy wheel changes to accomodate the tire options. I appreciate that this bike takes me places like the above picture.
New to the Table:
Salsa has not given up on this bike by any stretch. They have revamped the fork/frame geo to allow the option of a suspension fork and their new Anything Cage. Also Salsa has a slew of new racks that will work much better than anything I have tried up to now. Also, it come in Ti as well. Yeah, so combine the 'I'd sell all of my bikes but this one' mentality with a Ti version over Chromo. Think about that for a second and picture your garage with A bike in it, clean, tidy, spacious. Yet you can't seem to get that grin off of your face, weird.
Recommendation:
If you plan on riding a bike to something that isn't pavement, and riding from there, ever. Buy this bike. LOVE IT!
P.S. I warned you it was biased.
P.P.S. I'm working on kid toting solutions currently. As soon as The Kiddo has an 18" circumference head and I have something to put him in I'll let you know what has worked well for me.
