  • £8.99
  • RRP £49.99
  • Saving you £82

Shimano Deore XT M780 RapidFire PodsDelivering quick and dependable shifting performance, this shifter pod features a robust aluminium construction, which makes it durable on the most demanding of mountain bike (MTB) riding conditions. Coming complete with Rapidfire Plus technology, this version also allows you to shift down three gears with just one shift stroke.Features: Body Material: Aluminium Lever Material: Aluminium Cable Material: Stainless Steel Use: MTB Type: Rapidfire Plus Single or Pair: SingleTechnologies: Rapidfire Plus: Rapidfire Plus has been used by mountain bikers since 1985. Rapidfire Plus is still the first choice for a wide range of riding groups, from Cross Country racers to freeriders and downhillers. Rapidfire Plus is suitable for fast shifting. The rider can shift down up to three gears with one shift stroke. 2-Way Release: All newer Rapidfire Plus shifters are equipped with 2-way release (release in two directions). This means that the shifter cable is released by pulling with the index finger or pressing with the thumb. Instant Release: Instant Release shifting replaces the two-stage click and release shifting you are familiar with. Instant Release shifting releases cable as soon the lever is activated, resulting in the quickest possible gear changes. Whether it is an upshift with a top normal rear derailleur or a downshift with low normal rear derailleur a quicker shift is always a better shift. Multi Release (10-speed only): In earlier shifting systems, gear changes in one direction took place faster than gear changes in another direction. With Multi Release, two gears can now be changed with one lever actuation. The result: The fastest possible gear change in both directions, regardless of the type of rear derailleur used.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Brooks England Proofide Leather Saddle Preserve - 30ml Tub}
  • £8.99
  • RRP £10.99
  • Saving you £18

Brooks England Proofide Leather Saddle PreserveSpecifically created for use with Brooks England’s range of classic and modern style leather saddles, this Proofide Leather Saddle Preserve isn’t just to make your saddle shine, it assists with the custom moulding process that the saddle’s leather makes as it conforms to your individual shape. Made with natural ingredients, it keeps your saddle supple and also makes it showerproof.Proofide is the only substance that should be used to care for your Brooks Leather Saddle. Apply a little Proofide to the finished side of the leather, allow it to permeate until dry and then polish off. Proofide should be used several times during the 'breaking-in' period and every 3-6 months thereafter. On bicycles not fitted with mudguards, an initial application to the underside of the saddle will be beneficial, this needs not to be polished off. The leather gets its colour during the tanning process and it is possible, therefore, that some colour residues will remain. It is recommended to polish the saddle with a soft cloth before first use. Features: Genuine Brooks England Product An essential requirement for Brooks England leather saddles Softens saddle leather to help it to mould to your shape during "breaking-in" Showerproofs your leather saddle Various tub size options availableBuy Brooks England Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
