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.
Cyclescheme can save you up to 39% on a bike and accessories. Visit our Cycle to Work Scheme page to learn more and claim.
Trek Domane AL 4 Road Bike 2019
The Trek Domane AL 4 Road Bike has do-it-all capability and comfort-enhancing technology at a price point that won't break the bank. The carefully engineered endurance fit and geometry put the rider into an optimal position for all-day comfort without compromising speed and efficiency, so you are fast and stable.
The classy look of the sweeping IsoSpeed Carbon fork delivers more than just aesthetics by optimising the wheelbase, increasing compliance and smoothing out the road, easing the resonance of vibrations from rough surfaces. Extra clearance means you can fit a wider tyre and tackle rougher surfaces, from towpaths to potholed country lanes, and with mudguard and racking mounts you can even plan bigger adventures and explore new roads further afield. Should you encounter any hills the 10-speed Shimano Tiagra groupset with a compact chainset and 11-32t cassette will have plenty of gears for when things get steep.
Features
- Shimano Tiagra groupset
