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 Procaliber 8 27.5"/29" Mountain Bike 2019
The hydroformed aluminium frame of the Procaliber 8 27.5"/29" Mountain Bike feature’s Trek’s IsoSpeed decoupler, which allows the seat tube a small amount of movement independent of the top tube in order to add more compliance without adding the weight or the complexity of full suspension. The RockShox Recon Gold RL Solo Air fork adds 100mm of travel to the front end, with Boost110 keeping the steering as precise as possible, and a remote lockout provides efficiency on smoother trails or tarmac.
The Bontrager Kovee Comp 23 wheels and XR2 Team Issue tyres are both ready to be set up tubeless, allowing lower pressures to be used without the risk of pinch punctures for greater comfort and grip. With a single 30 tooth front ring and a huge 12-speed 10-50 cassette, the range of gears is sufficient for the very steepest, toughest of climbs, whilst Shimano’s MT500 hydraulic disc brakes ensure that the descents can be enjoyed with confidence.
