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.
We offer a free safety check after six weeks or 200 miles, so you can keep riding in confidence. Visit us now in-store to discuss your new bike.
Cervelo S5 Dura Ace Di2 Road Bike 2017
Top of the range, whether tackling an epic gran fondo, road race, time trial or competing in a triathlon the Cervelo S5 Dura Ace Di2 Road Bike 2017 is ready for whatever terrain you want to tackle. One of the most aerodynamic road bikes on the market, using many design cues found on Cervelo’s P-series time trial frames, the S5 is stiff, lightweight, incredibly fast. Adorned with Shimano Dura-Ace 9070 Di2, 11-speed components, with a Rotor 3D+ BBright™ chainset, HED Jet 6 Plus wheels and a Fizik Antares saddle. There are many new changes for 2015 including a stunning black and white colour scheme, sure to make you turn heads as you ride along.
The S5 is phenomenally fast and stiff. With a wider, more aerodynamic headtube and fork, housing a tapered steerer and now offering 25 millimetre tyre clearance. You can now get lower than ever before, with a lower stack height than it's predecessor. With a 35% increase in stiffness in the head tube, this is a real race ready bike.
The dropped downtube design is incredibly aerodynamic and wraps, seamlessly, round the front wheel. Staying hydrated has never been faster than with the Cervelo S5 Frameset 2016, incorporating carefully placed bottle cage bosses, allowing perfect efficiency in the wind, whether using bottles or not.
Future-Proof Cable Management is a nice touch, resulting in the frameset being compatible with electronic and mechanical groupsets as well as hydraulic shifting and braking setups.
Shielded seatstays promote smooth airflow and give the bike a wind cheating advantage over competitors. Upfront and the Cervelo All Carbon tapered fork is stiff, compliant and creates little in the way of drag.
The Rotor PF-30 BBright™ bottom bracket shell is now 6% stiffer than ever before providing even more direct power transfer to the pedals.
The S5 uses only the finest finishing kit, with HED providing the stiff, lightweight, responsive and aerodynamic Jet 6 Plus wheels. These have been supplied with grippy, durable Continental Grand Prix tyres and Italian saddle specialists, Fizik, have added their ultra-comfortable, high performance Antares saddle.
Cervelo and FSA add the finishing touches, with a FSA OS-99 stem and Cervelo, All-Carbon, Aero handlebars, stiff, lightweight, to provide a comfortable but direct ride.
Ideal for road racing or triathlons, the Cervelo Aero seapost offers enough adjustability for you to dial the perfect position.
