FWIW, Smallest Clearance is inside the rear drive side Chainstay , where the factory Presses in a Dent. . NDS is a Bigger Gap

M3L Mk-4 frame Regular Schwalbe Marathon K tires ( I have an old MTB wearing the Studded Tires, at the ready)

A Measure your Tires for width or Height would be useful , (if worrying while they are Enroute.. then you will know after you fit them)



IDK if the casing is the Smaller Kojack 32 that they then mold the lugs onto, for enough rubber to hold the studs .

Logically that would seem Appropriate, rather than the wider 37 casing ..

Bike Friday's Tikit has Greater Clearances around the Wheel.
