Hi all and thank you for letting me join this group, I have a cannondale caad 3 and probably 13 years old, still a good bike and I've ride to Paris twice and done plenty of other rides, my daughter who is 19 now wants to ride to Paris, so I've managed to buy her an exact same bike as mine apart from the sprocket and caset are different, so need to change them for something easier to pedal, it also needs a service, now my question is should I spend money on doing this or should I try and find her a newish cheap bike, I actually still like my bike and its never given me any trouble.
