I'm slowly building up a bike and the forks on it are ancient. A guy is selling some Duke Race (2003 he thinks) shocks that will fit for around $50. I'm going to go look at them tomorrow but I don't know what to look out for.
He's not the 1st owner and has only ridden them about 70 miles, he sayshe took them to a bike shop, they did a look-see and said they need new seals which are like $15.
What can I look for, how can I test them to check that they're OK? What could potentially be wrong with them? Like, how do forks like that get busted, I guess? Also, I don't know anything about maintaining them, I'd need to buy a pump, right? What else?
Assuming they look fine on the outside, what could be wrong with them that wouldn't be too far-fetched? If they needed a complete rebuild, would that be possible still and how much would something like that cost?
Lots of questions, i know, I just seriously know nothing about shocks. Thanks.
