GRAVEL40 mm
Challenge Gravine Pro HTLR 40mm
Imported as Challenge Gravine Pro HTLR 40
The Gravine is Challenge's most aggressive gravel tire, sporting taller, more open lugs designed to provide traction in muddy, loose, or technical hero gravel conditions. Built on the same 260 TPI handmade casing as the Getaway, it offers elite-level flexibility and grip for riders who venture beyond maintained fire roads.
