Dome capping has been used for a few years on our popular Blazer and CKS forks, as well as on our Loden and Calico frames. We realized that some riders might not be the most familiar with this style of dropout and why we chose to use this unique shape/process, so we thought we’d get our product designer Darcy Saccucci to explain it
There seems to be some confusion about the domed bottoms fork legs at the drop out area of our Blazer and CKS forks. Lets clear it up. The rounded area at the bottom of the forks is there to eliminate two weak spots on how forks are traditionally built. Most forks have a tube that is cut and then a cap is either brazed or welded over the end of the fork leg, this cap can often become damaged from grinding. The CKS and Blazer forks’ domed end is the actual tube that has been formed to that rounded shape, it’s not a separate piece that has been added. The second and largest advantage of the domed legs is that using this eliminates the 90º corner that has long been the weakest spot on drop outs. By making one long sweeping weld, that is actually welded to the fork leg and not separate cap welded on cap, the stress that can typically cause a fork drop out to fail is spread out over a greater area which reduces the focus of the impact that forks take from hard landings and crashes.
Basically there is a lot more to these forks than just looking good.
