P-BIKES DECREE SL9
BRITISH RACING EDITION

Watch the build.
Meet Jon, the mechanic and filmmaker behind The Cycle Workshop, with over 50,000 subscribers and more than 8 million channel views behind him. He's building the DECREE SL9 from bare frame to finished bike, taking you through the components and assembly on camera.
A bike this good isn't built by one person.
It took nine specialist component brands saying yes to something ambitious. Each one a collaboration, not a purchase order. Jon at The Cycle Workshop ties it all together — camera rolling on every stage.
Wind-tunnel-tested carbon wheelsets, hand-built and inspected in Belfast.
TPU tubes engineered in Aachen — up to three times lighter than butyl.
Crank-based power meters that show exactly what you put into the bike.
Ceramic bearings and pulley wheels, finished in over 150 hand-applied colours.
Precision CNC-machined parts from Copenhagen, raced in the WorldTour.
Precision-machined bottom brackets built to an uncompromising tolerance.
The world's lightest carbon thru-axles — a pair from just 30 grams.
Power meters, GPS heads and sensors that make every watt count.
Aerospace-grade titanium bolts, anodised gold.

Extraordinary spec.
Unbelievable value.
A Toray T800 + T1100 + M40J carbon frame, Shimano's flagship Dura-Ace Di2 and hand-built Scribe Élan Ultra 5 wheels. The DECREE SL9 brings this level of specification together with premium finishing details, without losing sight of value.
Built by one mechanic.
Your DECREE SL9 is fully assembled by Jon of The Cycle Workshop, not passed down an assembly line. He plans the build, fits and torques every part himself, and tunes it until it's as close to perfect as a bike gets. Every stage of the build is on camera.
