Troy Lee Designs D4 Composite HelmetA classic of the mountain bike world, the Troy Lee Designs D4 Composite Helmet has a well-won reputation for delivering superb levels of comfort, protection and distinctive style. Pull it on and go get your mountain bike thrills in style. No matter where you get your mountain bike thrills, from weekend races on challenging downhills through to racing buddies to the bottom at the local trail centre or bike park, the D4 Composite Cycle Helmet has you covered. Confidence is given a boost thanks to its superb combination of safety features, unrivalled comfort and the usual Troy lee flair for design. Keeping weight low but protection and durability high is the aerospace-grade fibreglass composite shell. This wraps around an impact-absorbing EPS foam core - the forces from any crash are absorbed and dissipated by this core, offering outstanding crash protection. Meanwhile, breakaway screws prevent the visor from catching on the ground and help prevent neck injuries. Lastly, MIPS (Multi-directional Impact Protection System) provides excellent brain-injury prevention - more on that below.MIPS (Multi-directional Impact Protection System) The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head.Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head.Uncompromised ComfortWith this level of protection and head protection, you may think ventilation is compromised. But not a bit of it. Troy Lee have carefully engineered the outer vents and inner channels to work with the headliner so fresh air is free to circulate and keep you cool.Inside the D4 you'll also enjoy the brilliant XT2 washable liner. Lesser helmets will use standard foam liners which after continued use can soon start to feel uncomfortable and even itchy. Not the XT2. This anti-bacterial liner ensures no nasty odours or itchiness, and being washable you'll be able to keep it fresh for every ride.Tough, durable, protective and yet lightweight, the D4 Composite is the ideal full-face helmet for the weekend DH racer and avid mountain bike trail slayer.Features:Aerospace shell design and materials (D4 Composite)MIPS C2 brain protection systemFront air intake system with high flow through polymer centre and powergrid side meshCollarbone suspension systemBreakaway visor screwsX-static® and XT2® Anti-Microbial/anti-order paddingQuick-release contoured 3D cheek pads create an anatomically optimized fitWeight - 1050gCPSC 1203*, CE EN1078*, ASTM F1952 - DH, ASTM 2032 - BMX, *Varies by regional standardsShop all MIPS helmets - Click hereBuy Troy Lee Designs from Chain Reaction Cycles, the World's Largest Online Bike Store.

Please Note: This tyre is listed as a clincher tyre, but it is a specific tyre of tyre that brings you the benefits of a tubular tyre, that is only compatible with clincher type rims. It is called a "tubular clincher" type tyre and cannot be used on tubular rims. The thinner tread of this road bike tyre also lowers rolling resistance while the tyre is maintaining ideal shock absorption properties and high puncture resistance. How Does the Tubular Clincher Tyre Work? When inflated, the tubular clincher (see image below), in the same way as a tubular, is pressed towards the rim. Simultaneously, the bead blocks of the profiled rubber band spread out embedding on the rim shoulders and eliminating any rotation of the tubular clincher against the rim as well as the possibility of the tubular clincher unseating. As the tubular clincher is inflated, the band side literally 'bite' into the rim shoulders. Benefits of Tufo's tubular clincher tyres: high inflation pressures - up to 15 bars (220 psi) without any damage to the rim walls, even in a case when the rim manufacturer specifies lower inflation pressures (the pressure is contained inside the tubular clincher and does not affect the rim wall), same riding quality as with tubular tyres, safe handling in case of punctures (the stability of a rider is not affected), the tubular clincher can be ridden when flat, and the fastest and easiest installation and dismantling without any tools.
Tufo C Hi Composite Carbon Road TyreThe application of composite puncture proof ply and high composite carbon tread compound on this Tufo Tubular Road Tyre is proof that it is possible to use a thinner tread and still maintain high mileage. Thinner tread reduces rolling resistance, but the C Hi maintains ideal shock absorption properties and high puncture resistance.Featuring Tufo's unique patented Tubular Clincher construction, there is no extra investment in switching from clincher tyres to tubular clincher tyres because you can use the same Clincher rim. Riding properties are equal to those of tubular tyres.How does the Tufo Tubular Clincher work?When inflated, the tubular clincher, in the same way as a tubular, is pressed towards the rim. Simultaneously, the bead blocks of the profiled rubber band spread out embedding on the rim shoulders and eliminating any rotation of the tubular clincher against the rim as well as possibility of the tubular clincher unseating. The bottom profiled bead band does not function only as a filling in the area between the rim and the tubular clincher but also plays an active role. As the tubular clincher is inflated, the band sides literally “bite” into the rim shoulders. Features: Low rolling resistance, low weight No need to use a rim tape nor glue The easiest and the fastest mounting from all the tyre types, no tools required Distinctly the safest behaviour in case of flats without effecting the rider's stability, can be ridden flat in case of emergency Can be used immediately after mountingType: Tubular Clincher - Designed to fit a Clincher Rim profile only Use: Racing/Training Size: 28" Pressure: 8-12 bar (115-175 p.s.i. - 22mm) / 6-8 bar (90-115 p.s.i. - 25mm) TPI: 120 Sidewall area, 240 Under the tread Rim Size: 28" 700 C E.T.R.T.O: 622x (13-15) mm Weight: 335g (22mm), 375g (25mm)Note: This is a Tubular-Clincher Tyre, designed to fit a Clincher Rim profile (NOT Suitable for Tubular Rims)Buy Tufo Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Zipp® developed the Tangente™ High Performance Cork Brake Pad as a response to the intense heat caused by braking on carbon. These pads are designed for our carbon rims and employ a composite cork polymer to reduce glazing and offer consistent brake response. As a result, the Tangente cork pad avoids the brake pulsation produced by residue buildup from rubber pads and can even eliminate pulsation from rims with previous buildup.Even though the newer silver Tangente Platinum Pro Brake Pad is designed to perform better across all riding conditions, we realize there remain fans of the smooth consistent feel of cork.Tangente High Performance Cork Brake Pad’s unique shape places more material in the front of the pad to improve durability and shed water. Although the composite material wears similarly to low-temperature rubber compounds, the Tangente cork pad lasts longer than most rubber carbon-specific pads because of its shape and 0.5 mm greater overall thickness.Select Shimano®/SRAM® or Campagnolo® stylesThe Tangente pad may be used on any tubular or clincher rim with a carbon braking surface, but it should never be used on aluminum braking surfaces.
