Pirelli P Zero 4S Velo Road Bike TyreThe smart cyclist’s road tyre choice for riding through all four seasons, the P Zero 4S Velo brings you a fast roll and consistent grip, even in wet and cold weather. Ideal for use on inclement days when the weather is changeable, Pirelli has made up its tread with three distinct areas, to give you reliable traction at all angles. These include grooved side bands, semi-slick shoulders and a smooth centre for maintaining your speed. Now you can grab your bike without having to check the weather forecast first.Water-Shredding Tread DesignPirelli's Functional Groove Design (FGD) technology provides a unique tread design where the grooves are deeper in the centre of the tread. These grooves get progressively shallower toward the edges, guiding water off the tyre to give you confidence-inspiring grip in the corners.Features: Tyre Type: Clincher Bead Type: Folding Compound: SmartNET Silica Puncture Protection: Yes, Aramid fibre breaker layer Casing: 127 TPIUse: Road training/racing in wet or dry weatherTubeless Compatible: No Weight: 220g (700x25c)Technologies: Functional Groove Design (FGD): To fine tune the tread pattern of PZero Velo tyres, Pirelli drew from their motorsport technologies and inspiration from their Superbike Diablo Supercorsa tyre. This tread pattern does not only have an aesthetic function, it maximises performance in terms of water outflow, dry and wet grip, mileage. It also aids excellent tyre response as well as boosting both comfort and handling SmartNET Silica: This is Pirelli’s patented cutting edge compound and excels in every performance area. With its unique formula, developed through years of leading experience in motorsports, SmartNET Silica provides cyclists with a truly uncompromising experience. It offers low rolling resistance, enhanced wet and dry grip, long mileage, high puncture resistance and a low weight Ideal Contour Shaping (ICS): For the contour and construction of PZero tyres, Pirelli made use of ICS (Ideal Contour Shaping) technology to work on the shape of the tyre's contour. The use of CAD software along with the subsequent analysis of the finite elements, helped to optimise the construction parameters and repeatedly simulate performance. This has resulted in PZero providing the best and most efficient footprint for cornering grip, stability and a reactive response to riding straights, descents, or bendsBuy Pirelli Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Traditional tyres are designed around older, narrower rims and create an overly square tyre profile, leading to less than optimal performance. WT tyres obtain peak performance when used with an inner rim width of 35mm, but are proven to perform exceptionally with rim widths from 30 - 35mm.EXO Protection: Maxxis EXO tyres feature an exceptional cut-resistant and abrasion-resistant material added to the tyre sidewalls. This densely woven fabric is very lightweight and is very flexible, which guarantees that the performance of the tyre is unaffected. The EXO Protection is a superb choice for rocky, aggressive and technical trails where the chance of sidewall cuts is high.Tubeless Ready: Tubeless tyres provide many benefits: they offer the ability to run lower air pressures, which dramatically improves traction; it provides a lower rolling resistance compared to when using tubes and a drastic reduction in the change of getting a flat tyre since there is no tube.Buy Maxxis Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Don't be fooled by the title, Enduro have been producing bearings since before the word "Enduro" became fashionable, there bearings are an industry leading design and they set the standard for all other bearing manufacturers to match. You may be more familiar with the ABEC standards from the worlds of skateboarding and roller blades but Enduro have tailored their bearings for the specific demands of cycling. The entry level industry standard of a bearing is ABEC 1 but Enduro do not produce any bearing which comes in at less than ABEC 3, this means that even if you choose an entry level Enduro bearing it is of better quality than another manufacturers entry level bearing.Enduro were the first company to produce a truly sealed full ceramic bearing and this selection for your bike will make it run like a dream.NB: Sold Individually, not as a pair
