That is quite interesting actually, I bought my son a bike from halfords and he loves it except he claims that the front suspension keeps 'bottoming off' or something like that (what ever it means). The bike I bought him was an Apollo Paradox 20" with what I think is the same front suspension that Music Guy has (sr suntour m2000 I think!). Is there a cheap upgrade for this, I don't really want to spend lots. The first link that Music Guy put seemed just in my price range, would it be any good???

As you can probably see from reading what I have put, I am not very knowledgeable on this subject. Any help would be much appreciated.
