-Singlespeed was the only way to go for sure.
-24-22 gearing was great or 22-20.
-No brakes, the grit & sand destroyed the bb7's in less than a week and we eventually took them off. We didnt really need them anyway.
-Fixed is not a bad idea at all, For pugs, running a fixed on the front as backup is the way to go, the bmx freewheel stopped turning by hand after a few days due to lack of seals. That being said, both our freewheels (shimano & DT) worked fine the whole trip.
-Phil wood bb's are still spinning slop free - This is nothing short of totally amazing.
-Chains took serious abuse, stainless might be the way to go for longer trips.
-Surly tubes are bomber, zero flats and their ease of patching was good piece of mind.
-OMM Racks were bomber as expected, they were beat up hard and held up great.
-Checking the tightness of chainring bolts is pretty darn important...
