Simply Flies

Big wheels, mid-travel, ready-to-rip geo.

Built to do it all.

The Starling Cycles Murmur Trail combines 29″ wheels with 140mm travel and our hand-built steel frameset.

The little brother of our big-hitting Murmur Enduro, the Trail is built to go anywhere and ride anything. From your favourite tech trail, to a local enduro race to those epics in the hills. The Trail will fly through it all.

That unmistakable ‘feeling’ of steel, big wheels, short-travel and perfect geometry make this a hell of a bike. It’ll haul ass through rough, nasty terrain but remains lively, responsive and easy to rip back up for another run (and another, and another).

For all-day-epics to local laps. Go anywhere, ride anything.

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. “
