Eleven Centre Shaft

The Eleven Centre Shaft is the center-shafted build within Odyssey's Eleven line, and the maker's page for the closest matching model, the Eleven Tour Lined CS, describes it as "a center shafted face-balanced mallet best suited for golfers with strokes that have minimal face rotation and arc." That page pairs the head with "a super high MOI, forward CG, multi-material head design with our new Stroke Lab shaft, legendary White Hot insert, and tour preferred single alignment line."

Golf Monthly's reporting on the Centre Shaft variant lines up with that description, listing it with a centre shaft neck and face-balanced toe hang, though that account comes from the publication rather than the maker or a verified spec, so it should be read as their reporting rather than settled fact.

Within the Eleven family, the maker's own prose frames the line as offering "three proven options for better aim: a Tour Lined version, Triple Track Alignment, or a classic, unlined model," with the various head shapes split across toe hang builds, like the Eleven S and 2-Ball Eleven Tour Lined S, and face-balanced, center-shafted builds like this one. The maker positions the whole Eleven shape as an advance on "the forgiveness and alignment properties of our major winning Ten model," with the Centre Shaft sitting on the face-balanced, straight-stroke end of that spread.
