Your Wisper bike has a mechanical rear derailleur that will automatically tension your chain.
If you find the chain is loose, frequently comes of or is skipping gears, please seek advice from your Wisper Dealer.
Front and Rear brake pads must be replaced if the pad material wears to less than 1mm.
Brakes should lock the wheels before the brake lever reaches the handlebar.
If the lever reaches the grip or feels spongy in its action please seek immediate advice from your Wisper dealer and do not ride the bike
Handlebar grips or handlebar end plugs must be replaced if damaged, bare handlebar ends can cause injury
