Simply Performs

Big wheels, big travel, big performance.

The racer’s choice. Built to go flat out between the tape or in the mountains.

The Starling Cycles Murmur combines 29″ wheels with 135mm/150mm rear travel and our award-winning steel frameset.

The Murmur is built for raw speed, bags of confidence and full control. It’s the perfect choice for privateer racers, bike-park lappers or big-mountain senders.

And now, for Autumn 2022 and beyond, introducing V3 of the Starling Cycles Murmur.

V3 brings a whole heap of subtle but significant updates. We’ve combined ‘Enduro’ and ‘Trail’ models with a simple solution to combine both options into one frame, using an adjustable shock mount. The seat angle has been steepened for a better pedaling position and we’ve raised the BB a touch to add manoeuvrability.

We also now have an aluminium insert in the seat tube to stop seized posts, a stronger anti-flare headtube, a better-looking asymmetrical headtube gusset and we’ve moved the main pivot to the swing arm for a wider interface. Last but not least, we have a new cast main pivot part, which is neater and stronger than ever.

For raw speed. Between the tape, the bike park or the mountains.

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. “

Introducing Puffin pedallers mountain bikes

Previously known as Starling Cycles, Puffin Pedallers was born out of a commitment to the hard yards of mountain biking. No assistance, no engines, no driver-assist style technology. Just a rider, a bike and the mountain.

When you’re puffin’ on a Puffin no one will be in any doubt that you’re working hard and earning those descents.

Our new website is coming soon. In the meantime, please continue to use the existing Starling Cycles website.
