The Starling Cycles Murmur is our award winning 29” mountain bike frame, hand built in Reynolds 853 steel. Praised by riders and media alike, the Murmur proves that Starling’s beautifully simple and single pivot bikes can take on and beat the fastest bikes going.

With 29” wheels and 140mm rear travel the Murmur is built to feast on natural, technical trails. It’s easy to setup, easy to maintain, easy to ride and easy to go fast. Dan Bishop soared the Murmur to the overall British National Enduro series title win, beating scores of overly-complicated, overly engineered bikes.

The Murmur brings together a perfect combo of easy to ride, easy to throw around geometry with the stability and speed of 29” wheels. If you like going insanely fast through tough and technical trails, the Murmur is the one for you.

The Starling is easily one of my top two favorite 29er trail bikes. It should meet the wishes of many riders looking for something a little different to the norm, from a niche steel-maker. The modern angles make it easy to ride up and down a wide range of terrains, with a forgiving character that will make your riding life easier.

As one who likes to hold on to bikes for a while, 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.

Un-confusing, simple, well made, unique, fun to ride, at a great price and fast. McEwan has fashioned one hell of a bullet, created a benchmark, one of the best bikes we’ve ridden this year. Performance delivered, expectation raised.

The ride quality offered by the steel tubing gives exceptional grip and a comfortable ride… the Murmur can be a seriously fast and capable bike.

The comfortable speed it offers compared to most bikes is phenomenal but it has one extra attribute which many other “so called” enduro bikes don’t possess; the Murmur would not be too out of sorts if spending the day on the gnarliest of DH tracks!

The frame is a beautifully embellished work of art… The super-low 330mm BB height combined with subtle lengthways twist in the frame keeps the rear wheel glued to the ground and the bike feeling amazingly calm as you barrel through rocks

Very, very capable – find a lip, dig those heels and pick up, the Murmur will deal with the rest. This is really where it excels – on fast, pumpy, jumpy trails or all day missions. Steeps are dispatched assuredly and rough trails equally as conquerable.

When the Starling really takes flight, is when it gets leant over, particularly on wet, rooty and off camber sections of trail where you struggle to hold a line or maintain grip.With the Murmur Factory you find yourself sticking the high line and cleaning the section without fuss.
