In reply to SteveoS:
My bike comes out of the garage,I use and abused for the four weeks,
After each ride I spray GT85 on all the metal bits,chain,gears, bolts, pedals ect,next morning oil the chain and away I go.
When its time to return to work I strip it fully down,re lube and grease everything ready for next time i come home.
If its totally caked in mud will give it a quick spray down.I find the bikes these days can take so much more punishment and can cope with the extra bits of trail and mud stuck in the rear cassette!
I do change my wheels for summer and winter,and ensure i use Stantion lube weekly on the shocks to keep them running smooth.
I completed a twelve day race in the Himalaya with a friend of mine,the only thing he did with his was check his breaks in the morning and oil the chain.His theory if it isn't broke don't try to fix it!
Just my to pence worth.
