MIDDLEBURN CRANKS ARE MACHINED WITH A JIS TAPER


MIDDLEBURN CRANKS WERE FIRST DEVELOPED IN 1991 AND SINCE THEN THE CRANKS HAVE UNDERGONE MANY REFINEMENTS. THIS IS THE LATEST ROAD CRANK WHICH IS DESIGNED TO WORK WITH EXTERNAL BOTTOM BRACKETS BUT ALSO WITH PUSH-FIT TYPE BOTTOM BRACKETS WITH THE USE OF A DIFFERENT AXLE LENGTH. THE DESIGN IS THE RESULT OF ADVANCED 3D AND STRESS MODELLING TECHNIQUE THAT ENSURES THEY ARE AMONGST THE STIFFEST CRANKS ON THE MARKET BUT ALSO LIGHT TOO. 


THE CRANKS ARE FIRSTLY HOT FORGED FROM HIGH QUALITY 7075 T6 ALUMINIUM. THEY THEN GO THROUGH A CNC MACHINE PROCESS AND THEN FOR HAND POLISHING AND ANODISING BEFORE BEING RE-MACHINED TO HAVE THE LOGO IN THEM. ALL OUR CRANKS ARE PRODUCED BY THE SAME METHODS SO YOU CAN BE SURE OF THE SAME QUALITY STANDARDS WHICHEVER TYPE YOU CHOOSE.

 

THE CRANKS DO NOT COME WITH THE SELF EXTRACTING BOLTS. THESE CAN BE PURCHASED SEPARATELY OFF OUR WEBSITE
