A virus shortened ski season has made me wish for nice enough weather for a ride or two. Today my wish came true and it was 43 degrees, sunny and calm. Not bad for March in Montana.

Stay safe out there.

It was sunny and not-quite-that-warm here.... so I wussed out and did chores and prepared a slow stew for dinner. But you have inspired me: tomorrow is supposed to be a hair warmer, and dry, so, out we go.

Your note about short wait times has me thinking about my bike in SS. Stay healthy out there!

Is Fork Tip Tuesday a thing? Well it is now I guess.

Slotting fork blades to fit the tips and brazing them is something that many have trouble picturing but in reality it’s simple if not fussy.

I think you can see the progression from marking where you want to slot the blade, to the two hacksaw slots, to bending away and breaking off the tab. It’s then filed to the perfect fit and the ends are beveled and the tip is dry fit into the slot. Then it’s a simple matter of cleaning, fluxing, brazing and finish work....and suddenly you have a fork tip that will be light and stiff and last a lifetime. Easy peezy.

I have no idea how many times I’ve done this since 1989 but it’s a big ass number.....10,000ish times would be a rough guess. I can certainly do it in my sleep or while singing along to the Dead Milkmen’s Bitch’in Camarillo at 11.

Muscle memory can be a good thing.

Great pictures Dave. I still marvel at how simple but elegant my Kirk frame is.

I was asked the other day about my Triple F Dropouts. The guy said something like “What’s the deal with those drops?” and I wasn’t sure what he was asking. In the end the real question centered around the design and how they are built into a frame.

My main focus when designing the Triple F (stands for Form Follows Function) was to simply make the smallest, stiffest, strongest and most easy to work with dropout that exists. Should be easy.

The design centers around the machined balls that will sit into the stays at any angle without having to slot the stay. The process of building with them is simple. First I make rings of filler material that get pressed into the ends of the beveled stay. It then gets fluxed and brazed and finally they get cleaned and shaped and polished shiny. I like shiny.

You can see just how simple it is in concept. It ends up being lighter and stiffer and stronger than anything else out there. Can you tell that I’m proud of them?

The Kirk Triple F’s go into most every bike I build and it’s been that way for many years now.

Thanks for reading.

dave
