Castelli have been manufacturing high quality cycling clothing for over 75 years. Known for leading the way with technological innovations, Castelli were the first company to do away with Wool cycling shorts and instead make them out of Silk. Over the years, Castelli has remained at the forefront of cycling clothing and provide clothing to some of the most successful pro cyclists and teams around.

Westbrook Cycles are pleased to offer a comprehensive range of Castelli clothing including jerseys, jackets, shorts, gloves and accessories that are all available both online and in store. If you are looking for some new cycling kit, Castelli is perfect for leisure riders, ultra-aero time trial riders, and everyone in between. When you buy Castelli from Westbrook Cycles you can be assured you are buying quality.


Don’t let a drop in temperature stop you from getting out on the bike this winter. Whether you’re planning to push your limits on training rides, or braving icy commutes, Castelli’s range of essential cold weather clothing is designed to keep you warm without holding you back. Investing in a quality pair of windproof gloves, or layering a thermal jersey with a wind-resistant, waterproof jacket, can make all the difference in the world in terms of comfort and ultimately, enjoyment.

Castelli’s Sfida jersey benefits from a special thermal fabric developed to offer additional warmth, with a high-collar design to keep out the bitter winds which are an unavoidable reality of winter riding. The Sfida jersey is also versatile enough to be used year-round, and can double-up by being paired as a base-layer with a jacket, or coupled with a lightweight vest, making the jersey an economical choice for those riding in an unpredictable climate.

The Alpha Ros AW jacket takes everything that was loved about the dry-weather version and has been adapted to include an innovative rain-resistant membrane which will keep out the worst of the rain without detracting from breathability and overall performance, allowing the Alpha Ros to excel, rain or shine.  

Castelli have also delivered a game-changing cold-weather tight with the LW Bibtights, offering enduring warmth through a thermoflex fabric panel which extends over the knee, as well as an additional waterproof panel to keep out up-spray.
