I just completed my first gear installation and have to say it is working a dream.
Apart from when I stand on the pedals and push - the gears then slip.
Can anyone suggest what could be the problem?

    what is actually slipping?
    what have you changed?
    what did you not change?

    If the cassette is worn a new chain will skip.
    First make sure it is indexed properly.
