Four great reasons to buy your bike from Sigma Sports
Sigma Sports has one objective - to help you find your perfect bike. Our friendly, knowledgeable staff ask you a series of questions to understand what type of rider you are and the type of riding you do. We can then identify the style of bike that best suits your needs.
Riding a bike that fits you perfectly will help keep you injury-free and ensure you enjoy riding further for longer in total comfort. We check your measurements on a jig to ensure your optimal set-up.
When you collect your new bike we'll double-check your position and make any micro-adjustments if required. We'll also discuss the controls on your bike as well as maintenance tips.

Cervelo S5 RED eTap AXS Disc Road Bike 2021
Combining the finest materials and components with a meticulous, aerodynamically inspired design, the Cervelo S5 Red eTap AXS Disc Road Bike infuses raw velocity into any sprint, solo break or challenging chaingang.
The highest grade of carbon is used within the frameset and is laid in a sophisticated format to afford stunning levels of lateral stiffness while remaining comfortable and lightweight. The reactivity promised by this carbon construction is complemented by TrueAero manipulated frame tube profiles, an innovative fork-to-frame junction and aero sculpted V-Stem and handlebar configuration that all combine to lower aerodynamic drag markedly.
Reserve 50/65mm wheels use their aero-tuned carbon rims to slice through the air while their wide inner rim width works in unison with the generous frameset clearance to reap the comfort and low-rolling resistance from using broader tyres. Propelling the ride is SRAM’s flagship, RED eTap drivetrain that uses its wireless, electronic setup to change through the gears with accuracy and reliability. This drivetrain also incorporates a Quarq power meter that is seamlessly integrated into the chainset to offer valuable feedback when racing or training.
A CeramicSpeed bottom bracket lowers rotational friction and is a professional-level addition to the build. Assured and precise braking is donated in all weather scenarios by the SRAM RED hydraulic disc setup.
