I have an older (mid 90's) sovos freehub (sorry if I'm not using the correct terms...) that I took it apart because it occasionally skips. The cogs inside were chipped in several places like I expected. For anyone who has dealt something like this... Does the part I circled in red come off so I can install a new freehub or is it integral to the rear hub? If it's integral can that outer shell of the freehub be replaced? If the freehub can be replaced does anyone have a recommendation? I don't need high end stuff for this bike. Thanks!
