Cheers Shovelon,
Thanks for your very helpfull comments I have now re-greased the chubbies and you are right they are now very smooth. Your instructions were very simple to follow. One question though, Where can you buy an extended 8 mm allan? to tighten the inside bolt of th bottom fork? The bolt under the fork just spins when you tighten it and I know from the instruction manual (from k2 website) that I need this long allan key to make it tight.
Is it just as well to take it to the LBS?
Anyway off to Carron valley to see how it fairs. Friend will be on a singlespeed fully rigid on-one, bit of a contract of rides :shock:
