Really if you look at the specs the Judy isn’t really all that different from the XCM that’s on your bike currently. I mean there are differences but to me they mostly cancel each other out. The Suntour forks are POS fork given a choice I’d ride the Judy over it any day but I don’t really see the value in getting the Judy as an upgrade. I’d be riding the Suntour until it blows up and I saved up enough money to get something with real performance gains vs replacing it with a marginally better/different fork like the Judy.
