Simply Flies

27.5" wheels, big travel, big geometry.

The original Starling. Built to go flat out between the tape or at the bike park.

The Starling Cycles Swoop Enduro combines 27.5″ wheels with 160mm travel and our much-loved steel frameset.

It’s built for raw speed and bags of fun whilst still maintaining that nimble, easy-to-ride feel of 27.5″ wheels.

It’s the perfect choice for privateer racers and bike-park lappers or simply anyone that wants a long-travel, ass-hauling steel bike that’s built around 27.5″ wheels.

If you’re looking for that perfect blend of good times, high speeds and low maintenance then the Swoop Enduro is the bike for you.

For raw speed and good times. From the bike park to the race track.

The Loam Wolf
Sep 2018
“The ride quality offered by the steel tubing gives exceptional grip and a comfortable ride. By fitting high-quality suspension units, the Murmur can be a seriously fast and capable bike.”


Fall 2020
“The Starling Murmur’s feel is second to none. Its raw stainless steel front triangle is elegantly simple and sleek, round tubing speaks of the beauty found in function over form. The Murmur is a bike that’s built to be ridden, plain and simple.”


Sep 2018
“This is simply a shredder of a mountain bike… The idea of a simple, low-maintenance frame that I’m not afraid to ride hard, put away wet, and toss into the weeds on occasion, is appealing. Perhaps a bit indicative of my predilection for slightly off-kilter rides, but this is the kind of bike I’d keep for a good long time, and never get bored of. “
