Oversize BB spindle - large 22mm diameter chrome-moly hollow pipe billet spindle reduces weight, increases strength and rigidity
This splined bottom bracket is designed for use with older Shimano road Octalink cranksets and features an oversized 22mm chrome-moly hollow pipe billet spindle which reduces weight whilst simultaneously increasing strength and rigidity. The unique Octalink splined axle / crank arm interface results in a more rigid crank assembly compared to traditional square tapered spindles by providing a greater contact surface area. The maintenance-free sealed cartridge design prevents corrosion making it ideal for year round use in the UK.

POC Octal MIPS Road Cycling HelmetPOC take their already superbly protective and award-winning Octal and integrate MIPS brain-protection technology to create the POC Octal MIPS Road Cycling Helmet. The best just got better. The distinctive design of the Octal MIPS Road Helmet is the first thing to catch the eye. But function and form are closely linked here, with ventilation, comfort and protection intertwined perfectly to create both a high level of performance and an eye-catching design.Safe to its CoreAt the heart of the performance is the safety provided by the combination of shock-absorbing EPS foam core, made thicker in more vulnerable areas, and MIPS (Multi-directional Impact Protection System) technology. In the event of a crash both work hand in hand to absorb and dissipate harmful impacts to the head and brain. The protection is further heightened by the extended coverage over the temples and at the back of the head. A unibody outer shell wraps the inner core, enhancing both durability and structural integrity all while minimising weight. Go With the FlowProtection is of course paramount. But comfort is also vital, and here the Octal MIPS excels. Firstly, large forward airflow vents are engineered to draw in air, internal channels keep the flow smooth and large exhaust vents dispel warm damp air. Cooling airflow is the result. POC also use Coolbest padding inside. This temperature-regulating pad minimises temperature build-up at the helmet to head contact points. Lastly, a lightweight size adjustment system makes getting the right fit remarkably quick and easy. The right fit means greater comfort and more security should you fall. MIPS Integra TechnologyThe MIPS Integra system brings together POC's 'whole-helmet' safety and design ethos with the brain-protecting technology of MIPS. This holistic approach sees every detail of the helmet engineered to work in harmony with each other, giving you new levels of integrated safety, comfort, ventilation, aerodynamics, fit and function.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.FeaturesHigh-performance EPS liner, optimized in densityFully wrapped unibody shell constructionGenerously ventilated, using POC's unique ventilation designSize adjustment systemStraps moulded into linerTemperature regulating Coolbest paddingEye garage to keep your sunglasses securely in position when placed on the helmetMIPS Brain Protection SystemWeight: 210g (S), 220g (M), 245g (L)CERTIFIED EN 1078, CPSC 12.03, AS/NZ 2063Shop all MIPS helmets - Click hereBuy POC Helmets from Chain Reaction Cycles, the World's Largest Online Bike Store.
