My gawd that’s stunning! That pivotal seat post makes my meat loaf. Bravo.

I introduced this quote at work and it clearly got overused in the last week. guess we did a lot of learning.

also did some learning on my own projects, just not quite sure on the lesson yet:

machining front triangle



my CNC is still acting up and i loose steps from time to time, but can't figure out why. must be an electrical interference issue or something. The nds front triangle took around 6h machining time and the CNC lost steps 3 times during that time. in the tooling board this isn't too big of a deal as everything can be fixed, but before machining the final frame i need to figure that out...

I've certainly gotten some mileage out of that one, I'm really glad it's found a new home!

I'm really excited to see more of your bike. That's an enormous project, I like it.

Damn sleepy, your frame mold is pretty intense. Me likey

I’m just getting into designing a full suspension. I’ve got a frame builder friend who’s been building for a couple years and we want to try a full suspension. Been tinkering on linkage X3 with a few dual link designs, which we’re pretty set on using.

I want a 130-145 travel, light and snappy, aggressive geo trail/light enduro bike
For the suspension I’m going for something pretty progressive with a higher leverage rate initially, around 3.0-3.4. And a lot of anti squat, around 160-170 static, and around 130 at sag. But also falling pretty quick, around 100 at 50% travel, - 20 at full travel. Idea being that It’s more oriented towards performing under standing/sprinting kind of efforts where you’re probably a bit past sag.
And a little higher anti rise, around 115-125, but also falling pretty quickly. Idea there being that I don’t mind a little squat on the brakes for the steep stuff. But with it falling quick it should keep it pretty minimal and active on bigger hits?

Couple questions… am I correct at all in thinking that a high initial leverage rate will help keep the initial travel pretty active and somewhat counteract the high anti squat? Or will the anti squat prettt much negate that?

Is there any negative to having an anti squat and/or rise that stays around normal levels for most it’s travel then drops significantly, very late in the travel? As in around -100+ In the last 20% of travel?

I feel like I can design something reasonable that’ll perform well pretty easily. But I really want to try something a bit different/risky just to experiment with it and see how it works out. Just trying to not go way out of whack and do something that straight up won’t work..

Hi,
Greetings from India,
Recently built up this single sided bike
Columbus Zona and Gara tubing
6-4 titanium BB axle and wheel axles
7075 hubs and crankset
6061 fork legs and crown
I've named it the " SINGLEMALT"

I take it you don’t lube the chain at all

There's almost 1 inch distance between the chain and the rotor. I'm also planning to attach a small plastic sheet between them to keep the rotors away from any oil

Looks great! Is it designed to solve a particular problem or just built that way for the sake of the challenge?

RAD! Rob English built something like this a few years ago. Actually a few of them I think. Nice work.

There is also some resemblance of the Laity from some time around the 90s.
Nice work!
