Lowside is like the grownup version of the bike you rode when you were a kid and still had hopes and dreams and some semblance of ambition. It’s just as happy riding singletrack as it is parked outside your favorite drinking establishment.
Lowside is a singlespeed. Singlespeeding has been a part of Surly’s DNA since day one when we launched the 1x1 Rat Ride. After a lot of Homie Fall Fests and more feats of strength than we can recall, we decided to discontinue it a couple years back. Lowside picks up right where the 1x1 left off.
“Some have dubbed the Lowside the ultimate pub cruiser.”
Modern trail standards: dropper post compatibility, 44mm headtube, Gnot-Boost rear spacing, thru-axles
Compatibility with most mountain bike standards makes it the perfect parts bin bike (no rim brakes allowed though)
Clearance for 26” x 3” or 27.5” x 2.8” tires
