Brooks England Proofide Leather Saddle Preserve - 50ml Tub}
  • £10.99
  • RRP £14.99
  • Saving you £27

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.
