Description
A bike that carries on the identity of the famous 1x1
"Lowside is like a very popular version of the bike you rode as a kid, still seeing hopes, dreams, and a little more ambition. It's as happy to ride one as it is to park outside your favorite bar."
SURLY's first frame was a dedicated single-speed frame called the 1x1 RAT RIDE. The LOWSIDE is the successor to that DNA.
The LOWSIDE frame is equipped with a rear derailleur hanger, so it can be used for both single speed and geared frames. It is also compatible with dropper posts.
The rear end is Gnot-Boost compatible with the same three hub sizes as the KARATE MONKEY and KRAMPUS, and tire clearance is 26x3" or 27.5x2.8". The front fork can be replaced with a 100 mm stroke suspension.
