Zoggs Hand Paddles are a great swim training aid for improving your stroke technique as they force your hand to stay straight as you pull through the water. They're also hydro-dynamically designed and feature a scooped front-end to catch the phase of your stroke with added holes to increase your feel of the water. Can be used on their own or with a pull buoy allowing you to focus solely on improving your swimming stroke technique. Zoggs Recommends... If you're considering training with hand paddles for the first time, you should always begin training with a smaller size (i.e. medium) regardless of the size of your hand.
Discover the ultimate swim training aid with the Zoggs Kickbuoy - a two-in-one combined kickboard and pull buoy, perfect for saving space in your kit bag! As a kickboard it can be used to focus on kick technique and as a pull buoy can be used to focus on arm stroke, a great training aid for working for different muscle groups.
Zipp 303 Firecrest Carbon Tubeless Rear WheelZipp's 303 Firecrest Tubeless rim-brake rear wheel is an all-arounder for a new era of road riding. It's rich in heritage yet loaded with innovations. It's as adept in the mountains as it is on rolling hills, windswept farm lanes, or ferocious field sprints.Tubeless Ready Road Bike Rear WheelAt Zipp, they never rest on laurels. This rear wheel features a 19mm internal width and is tubeless ready. That means you can run lower tyre pressure for greater cornering grip and compliance with reduced rolling resistance without the risk of pinch flats.Lightweight Carbon with ABLC Sawtooth TechnologyWhen it comes to pure speed, the 303 Firecrest Tubeless packs a serious punch. It's lightweight with ABLC Sawtooth Technology, a complex dimpling pattern first developed for the brand's top-level NSW wheel lineup.

Zipp 404 Firecrest Carbon Tubeless Front WheelZipp's legendary speed weapon, the 404 Firecrest, is better than ever. This go-to rim-brake front wheel is, for the first time, tubeless ready. That means you can run reduced tyre pressure for reduced rolling resistance and increased cornering grip and compliance without the risk of pinch flats. This front wheel's 58mm rim depth is a classic that has carried athletes to victory in every kind of event and situation - every triathlon distance, breakaways, field sprints and hilly finishes. Zipp's ABLC Sawtooth Technology uses a complex dimpling pattern to improve aero efficiency. Zipp's ShowStopper textured braking surface delivers unrivalled rim braking performance in wet or dry conditions. At the centre of the 404 Firecrest Tubeless rim brake is a versatile and durable hub, the German-engineered ZR1. If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless is a savvy and speedy choice.ShowstopperZipp's industry leading Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent. Showstopper is a complimenting pairing of a directional, moulded-in, texture with silicon carbide particles suspended in the surface resin. The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking.AerobalanceZipp's sole mission is to help you go faster.
