If the bike has an older 1" headtube then parts will be harder to find. If it has the now standard 1 1/8" headtube should be no problem finding parts for it.
The main problem is with 1" headtube is looking for a good suspension forks and stems that are 1"
White Brothers still do make 1" forks they might be the only one nowadays who makes 1" suspension forks, Chris King still makes 1" headsets on the stem it can harder to find.
You may have to go with a custom stem, check out our website =

All other parts should be available
