Campagnolo Potenza 11 Speed Rear Derailleur Rear Derailleurs
  • £98.99
  • RRP £121.99
  • Saving you £19

The Potenza rear derailleur takes a great deal of inspiration from the recently launched Revolution 11+ drivetrains and guarantees a similar degree of shifting performance as a result. Changing only the materials used in its construction, the Potenza 11™ rear derailleur is capable of shifting with the precision and speed of the Super Record version with the only compromise coming in the form of weight. In addition to the form and structure of the component Embrace Technology, introduced on the Super Record, Record e Chorus groupsets launched last year has been incorporated into the performance of the Potenza 11™ rear derailleur. The form of the external pieces allow the rear derailleur to move at a different angle and the internal design pulls the chain closer to the cassette. This translates into better power transfer, more secure grip, better chain/cassette interface and a longer life for consumable components. The chain will grip more teeth (when compared to rear derailleurs without Embrace Technology) and as a result disperse energy across a larger surface area, increasing the life of the cassette and lengthening the lifespan of the chain as well. By allowing the derailleur to work closer to the cassette in every position the athlete can now take advantage of perfect alignment between cassette and rear derailleur in any given gear. The internal structure of the original Revolution 11+ rear derailleur was modified slightly to produce the Potenza 11™ version in order to offer the same fantastic transmission while accepting larger gearing up to a 32 tooth cassette. The rear derailleur will be available in two versions; one with a 55mm cage and the other with a 72,5mm (Medium) cage designed to be compatible with the all-new 11-32 cassette.

Gloworm CX Replacement Optics - Clear - Spot}, Clear
  • £5.99

Gloworm CX Optic StandardThe CX Replacement Optics from Gloworm are replacement/spare optics that are interchangeable for different light effects and diffusion. These replacement optics are comaptible with Gloworm CX/Alpha cycle lights.Genuine replacement Spot/Wide, Spot/Spot or Wide/Wide optics for your Gloworm CX/Alpha Light.SPOT (96% Efficient/FWHM 17 degrees):The spot optic provides the narrowest beam. It is also the most efficient, allowing the greatest light output. It can be used in conjunction with another spot optic to gain the greatest possible output and therefore beam distance. This configuration is best used on the helmet to see down the trail or to spot the exit of a turn. Alternatively, the spot could be paired with another optic type from an alternative light pattern.WIDE (87% Efficient/FWHM 40 degrees):This optic provides a wide rectangular beam, it utilises the light output to provide more peripheral light and less light in the vertical axis. While not as optically efficient as the Spot Optic, it provides very good output for a wide-angle optic. Two wide optics can be paired as a great option for use on the road, however, when paired with either a flood or spot optic an effective hybrid beam can be created.Features: Genuine replacement Gloworm Optics Spot/Wide or Wide/Wide optics for your Gloworm for the CX/Alpha Light Replacement Optics Features: Standard: Spot/Wide Spot: Spot/Spot Wide: Wide/WideBuy Gloworm Accessories from Chain Reaction Cycles, the World's Largest Online Bike Store.

Gloworm Optic XS/X2 Flood (G1.0)The Optic XS/X2 Flood (G1.0) from Gloworm are replacement/spare optics that are interchangeable for different light effects and diffusion for G1.0 and G2.0 cycle lights.Genuine replacement optics for your Gloworm Light. Choose from either: Spot, Flood or Wide for the X2/XS G1.0, Spot, Wide or Honeycomb for the X2/XS/XSV G2.0 or Spot/Spot, Spot/Wide or Wide/Wide for the CX/Alpha. SPOT (96% Efficient/FWHM 17 degrees):The spot optic provides the narrowest beam. It is also the most efficient, allowing the greatest light output. It can be used in conjunction with another spot optic to gain the greatest possible output and therefore beam distance. This configuration is best used on the helmet to see down the trail or to spot the exit of a turn. Alternatively, the spot could be paired with another optic type from an alternative light pattern. FLOOD (84% Efficient/FWHM 25 degrees):For a smooth diffused light pattern the Flood optic is the best option. It takes the light and smooths the light across the width of the beam, making it slightly easier on the eye and creating even light from left to right. A pair of Flood optics would provide a wall of smooth light, however in doing so a significant amount of light intensity would be lost compared to a pair of spot optics. The flood is best used in tandem with a spot or wide optic. WIDE (87% Efficient/FWHM 40 degrees):This optic provides a wide rectangular beam, it utilises the light output to provide more peripheral light and less light in the vertical axis. While not as optically efficient as the Spot Optic, it provides very good output for a wide-angle optic. Two wide optics can be paired as a great option for use on the road, however, when paired with either a flood or spot optic an effective hybrid beam can be created. HONEYCOMB (87% Efficient/FWHM 30 degrees):Designed for use with the XSV, the Honeycomb Optic is used to gain a smooth diffused light pattern when used with 2 spot optics or other honeycomb optics. It takes the light and smooths it across the width of the beam, making it slightly easier on the eye and creating a more even transition from the bright beam centre. Features: Gloworm G1.0 The X2 and XS use the same single cone optics, whilst the CX and Alpha share the same double optics. The G1.0 XSV uses the same optics as the G2.0 XSV Gloworm G2.0 The X2 and XS use the same single cone optics The XSV uses the same optics as the G1.0 XSVBuy Gloworm Accessories from Chain Reaction Cycles, the World's Largest Online Bike Store.
