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.

Trek Lexa 4 Women’s Road Bike 2017
Part of the American company's women’s road range, the Trek Lexa 4 Women’s Road Bike 2017 features all the components you need to head out for day-long adventures on the road and explore. The main upgrade between the Lexa 3 and the Lexa 4 is the long-lasting, durable and high-performing Shimano Tiagra 4700, 10-speed groupset that’s perfect for spinning up the climbs or speeding along the flats.
Trek’s WSD-specific frame, Women’s Specific Design, allows you to remain comfortable on the bike at all times due to the enhanced sizing and fitting that’s specific to the female form. The lightweight and durable 100 Series Alpha Aluminium frame construction absorbs the roads bumps and vibrations for a much more enjoyable ride.
Trek’s carbon road fork has been incorporated to further lighten the weight of the overall bike, whilst also offering a more stable front end. This fork soaks up any vibrations the road may have to offer, alleviating any numbness you may get in your hands or shoulders.
A wide range of gearing is ideal if you want to head out and tackle hills and unexplored roads, and that’s exactly why Trek have incorporated the Shimano Tiagra 4700, 10-speed groupset. With a 20-gear range, this groupset is perfect for spinning up climbs and testing your performance, and as it’s mechanical, can be fixed by the roadside without an issue if anything does go wrong.
Bontrager T1 clincher tyres and Bontrager AT-750 double-walled alloy wheels combine to give a stiff and efficient ride. The wheels stay strong and ready for you to power you put through them. These tyres are highly-resistant to punctures and command a low rolling resistance, meaning you’ll go faster with less effort and maintain speed for longer.
Finished with Bontrager components, from the women’s specific Bontrager Ajna Comp Saddle, to the Bontrager Elite stem with computer and light mounts, you’ll be riding comfortably and efficiently for years to come.
