Fork post mounts

[Jussi Kettunen]

I'm looking ideas for coming forks with the post mounts.
Please show how you have done them.

Here's how I made the post mounts for my fat bike fork. I'm wondering if I need to add another gusset between the mounts, any thoughts on that?

I think that looks pretty stout. I'm planning on making a fat fork myself so interested in the comments that follow

Belltown Bikes came up with a method that makes mitering a little easier. It's a steel ball that has a flat and M6 hole.

These are my direct mounts.

Thanks for reminding soft polish steel ball method. That's something I would like to try in the future, should definitely make mitering easier.

Looks nice! I would be tempted to add some support to the bottom mount. Your current set-up would probably suffice just fine. The brake adapter is a gusset in a sense, but a little reinforcement adds extra hours of sleep down the road.

It's kind of funny how post mounts used to be less desirable in the off road past ( for fear of stripping threads), but now it's the new rage.

I'm still thinking of adding some support to the bottom mount, but I have not made the decision yet. I still have time to think about it before the fork leaves for the paint.

I found this from the Waltworks blog, Waltworks Bicycles: Not weird enough?

Actually, if you tie them together, it makes everything much worse - more ways to pull out of alignment. I figure the caliper will be the bridge, so as long as I get the threads where they need to be, it's good to go.

I was thinking about post mounts for a springtime project and after considering the ball-type, I am ordering the post mount made by Paragon. They make one for 135 & another specific to 142 thru axles. Is there anything they make that doesn't look and function well (other than some ugly dropouts)?

I´m kind of an overcautious guy.
(220lb, even considering my weight, I built myself some probably overdimensioned forks)
You probably don´t need the gussets between the mounts.

Those are my fork-postmounts.

If you haven't painted that move the lower cable guide up the leg a few inches.
Looks good!

Those look really good.
I think I will do something similar next time.
What size legs on that fork?

For a better lineup with the braking-hose ? The guides fit good imho. I always make a testfit with the brakes, Avid BB7 in this case. No sharp bends, aligned with the hose outlet of the caliper.

Looks good!

Thank you, love to hear that from one of my brazing idols.

I start with 1.1/8*0.058 seamless aircraft 4130.
Both forkblades get than customized on my lathe.
Left blade is short 0.058 section at the "crown", 0.035 in the middle and 0.040 at the postmount/dropout.
Right blade is short 0.058 section at the "crown", 0.030 in the middle and 0.035 at dropout
"Crown"-Segments are 1.1/8*0.058

"Butting" is done carefully, tubing carefully centered, smooth transitions, complete surface sanded, no scratches or scores.
The "butting" isn´t noticed with the eyes, only when touched.
