The Starling Cycles Murmur Factory Edition is our latest 29” mountain bike frame, hand built in Reynolds 853 steel.

The Murmur Factory is built around 29” wheels with 140mm rear travel and room for disc rotors up to 200mm and 2.6” tyre clearance. It is built for metric rear shocks and 148 x 12mm Boost rear hub spacings.

The ‘Factory’ frame has been designed at home in the UK and hand built in Taiwan by ORA, one of the World’s very best steel mountain bike frame manufacturing facilities.

The move to Taiwan was a considered one. As a frame builder, aerospace engineer and designer, Joe made the decision after visiting the factory and seeing first-hand the high quality of manufacturing, work ethics and working conditions.

ORA’s factory is the perfect setup for hand-crafting the new frames with expert engineers, boasting years of experience in building top-quality mountain bikes.

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.
