Iron clubs that have the same length, called Single Length Irons, are actually nothing new under the sun. What makes people talk about this phenomena now is Bryson DeChambeau. He won U.S. Amateur and NCCA Individual which makes him unique. Only 4 players achieved this deed before him, Jack Nicklaus (1961), Phil Mickelson (1990), Tiger Woods (1996) och Ryan Moore (2004).
What makes these irons unique is that every club head has the exact same lie, weight and MOI. The only thing that differs them appart is the loft. These irons are than built so they will have the same length all through the entire set. Normally, we recommend 37 inch which is the same as a normal #7 iron.
The theory behind Single Length Irons comes from the book "The Golfing Machine". In the book it is found that you will be able to repeat the same stroke throughout the entire set if the weight, lie and length is the same on each club. This is soemthing that the young physicist and golfer DeCambeau embraced.
