For most of conventional type aluminum racing forks , the cold forged crown & dropout were bonded to the aluminum blade ,the production process is labor intensive and the final fork is heavy.
Kinesis newest GL-11 SPF fork start with one piece straight/plain gauge aluminum pipe and turn out it into the one-piece fork by SPF forming technology.
It is more than 15% lighter than conventional type fork ,also there is no joint between crown & blade ,it let the fork has very smooth look and light weight.
Since the fork was built inside the mold and the tolerance of the fork is much better controlled comparing with the bonding/curing process.
