It depends on your riding. For casual snow riding on groomed trails at moderate speeds, a rigid fork is fine—the tire volume absorbs small bumps. For aggressive riding on rough frozen ground, washboard snow trails, rocky terrain, or bikepacking with a loaded bike, a suspension fork (RockShox Bluto or Manitou Mastodon) significantly improves control and comfort. If budget allows, a suspension fork is worth having.
