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 Checkpoint ALR 4 Women's Gravel Bike 2019
The Trek Checkpoint ALR 4 Women's Gravel Bike is all about versatility at an accessible price point. The go anywhere, tackle anything attitude makes this your bike of choice for gravel adventures, bikepacking and exploring new roads or simply commuting through the harsh winter months. Vast tyre clearance with space for up to a 45c width will deliver superior stability regardless of the conditions.

A women's specific saddle and vibration-absorbing carbon fork improve rider comfort, and in the worst weather your stopping performance is unhindered thanks to the flat mount hydraulic disc brakes.
