My used Rascal 89 Klein has a fixed (doesn't adjust up or down) seat post. The nose is up too high and uncomfortable on long rides. Any suggestions for a seat post replacement that won't break the bank? I don't race (yes I know this was once a racing bike but I love it and don't want to part with it yet) so I don't need anything fancy that allows one to easily adjust while riding. Just looking for a post I can adjust the nose down one notch and leave it there. Thanks.
