The Grappler frame kit from Surly is the ideal basis for a 27.5" Trail gravel bike. The MTB-heavy geometry, the large tire clearance of 2.8" and the option of dropper post mounting means you can also ride single trails with a drop bar without any problems. The numerous fastening eyelets for water bottle holders, luggage racks and bags make the robust steel frame ready for bike packing tours.
