The last thing you want is oil splashing onto your wheels rim or disk brake rotors - as this will lead to dangerous brake failure

Place a piece of cardboard between the chain and your back wheel

Place nozzle of chosen lube onto chain (only bottom section - as only this touches cogs) slowly turn pedals backwards and squeeze container gently to evenly apply oil to every link.

Wipe any excess lube off with a tissue / cloth and carefully remove the cardboard.

 

The simplest way to check the condition of any bike - pre ride or for regular maintenance -

Just lift it a couple inches and drop it

The bike should bounce (unless its a full suspension mountain bike) and be almost silent

Listen for any rattles - bangs - thuds that tell you something needs tightening up - adjusting or replacing

How often should you bikes chain set be de-greased ??
