Starling Cycles Murmur Factory 29″

Fast, simple, silent and steel. Designed in the UK, hand built in Taiwan


The new 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 2.5” tyre clearance. It is built for metric rear shocks and 148 x 12mm Boost rear hub spacings.

The new ‘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 Murmur Factory has been designed and tested in the UK and hand built in Taiwan by the experts at ORA.

Whilst our Murmur and Swoop frames are UK-made, the ‘Factory’ edition frame is hand made in Taiwan. By collaborating with ORA we’re able to produce enough frames to meet the huge demand whilst also keeping the quality high.

Of course, if you want a British built frame with custom geometry you can order one here.

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

Geometry and specifications

The Murmur Factory is available in three sizes – all are picked based on our experience of building custom bikes for customers. They’re designed to be stable and planted over rough terrain whilst remaining fun to ride and easy to throw around.

If you’d prefer a frame with custom geometry, you can go for one of our British-built and bespoke Murmur or Swoop frames.
