Not familiar with that particular Bontrager wheel but they tended to use DT hubs back then so a new freehub might be a possibility.
Otherwise there might be enough material to machine it for more space.
I had it done before on a few freehub bodies.
Hi all first post on here (was on years ago but no longer know my old login)
I'm after a steel road frame or bike with a 58cm top tube and eyelets for mudgaurds.
Something along the lines of Reynolds 531 or better.
Have a budget of up to £250.
