Blackett was introduced to the Calfee Sizer, a bike fully adjustable to the exact millimetre and angle. It’s used to replicate the optimum frame geometry for each individualOli Woodman/Future Publishing
Blackett’s figures from the Calfee Sizer can now be put forward for use with the BikeCAD softwareOli Woodman/Future Publishing
BikeCAD software is then used to simulate the frame and calculate exact dimensions. It can even be used to highlight potential overlap and clearance issuesOli Woodman/Future Publishing
The numerous cuts involved for the tubing is a laborious taskOli Woodman/Future Publishing
Once all cuts are correct, the lugs have to be offered up to the tubes – some are a very tight fit!Oli Woodman/Future Publishing
Miter cuts require a patient approach and demand absolute accuracyOli Woodman/Future Publishing
Head tube lugs have to be positioned exactly and require some gentle persuasionOli Woodman/Future Publishing
