Four great reasons to buy your bike from Sigma Sports

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.

Trek Lexa 3 Women’s Road Bike 2017
The Trek Lexa 3 Women’s Road Bike 2017 forms part of the American company's women’s specific road range, offering the same reliable base frame material as the Lexa 2, but coming with upgraded components and so offering a much more responsive ride in terms of gearing.
Trek’s WSD-specific frame, or Women’s Specific Design, allows you to remain comfortable on the bike at all times due to the enhanced sizing and fit 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.
If you’re looking to head out for day-long adventures with your friends, or go out with your local cycling club, then you need a wide range of gearing to take on the varied terrain. Luckily, Trek have incorporated a Shimano Sora groupset, with 18-gears to choose from, to power you up the climbs and along the flats. Perfect for anyone new to cycling who wants to test their limits and find out just how far they can push themselves.
Bontrager T1 tyres and Bontrager AT-750 double-walled alloy wheels combine to give a stiff and efficient ride. The wheels stay strong and ready for any power you put through them, without bypassing the low weight you need for a more enjoyable ride, and the T1 tyres are the ideal accompaniment. These clincher 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.
