Weighing in at just 90 grams, the 11 has been designed with weight efficiency in mind, without compromising on durability or quality. It retains Exposure's signature 6063 aluminium bodywork, precision CNC machined to perfection and finished in their iconic gunmetal grey hard anodised coating. This sleek yet hard-wearing exterior ensures the 11 remains both lightweight and exceptionally robust, built to last.
Inside, a purpose-driven architecture enhances thermal management, allowing for improved heat dissipation and consistent performance. This design enables the 11 to deliver greater output while maintaining reliability, efficiency, and longevity.

Why Buy From Us?
Free servicing, priority workshop and bike box hire
Free servicing, priority workshop and bike box hire
Selling bikes in Glasgow since 1980 — one of the longest-established shops in Scotland.
Built properly. Every bike assembled from scratch by our Cytech Level 2 mechanics, brakes bedded in, greased to suit a Glasgow winter, buddy-checked and test ridden before it’s boxed.
Free 6-week service. Cables stretch and spokes bed in over the first few hundred miles. Bring it back and we’ll re-tension, re-index and check every bolt.
Priority workshop, for as long as you own the bike. We never turn away someone who bought their bike here, however busy we are.
Free bike box hire. A hard-case Bike Box Alan whenever you travel with the bike.
Free changes at the build stage. Saddle, stem, bars, tyres, pedals — far cheaper before the bike is built than after. Add a note to your order at checkout.
Free test rides around Glasgow Green, on as many bikes as you like.
