It isn’t just suspension that isn’t new. This exact swinging fork design with the shock hidden discreetly in the steerer can be found on bikes at least 100 years ago, such as in the 1904 Columbia (American made) Model 138 to compensate for the harsh ride of solid rubber tires.

You’re thinking of the old 1st gen AMP forks that had a falling rate linkage and, though they had lots of room for improvement, were a pioneering effort in the new field of MTB suspension, also, it was a 4 bar linkage not a single pivot like this one. AMP gen 4 forks still fetch crazy money even though they’ve been discontinued for a decade. As James T rightly points out, the AMP main man also developed the FSR link which is the only truly efficient MTB rear suspension design ever made. I would argue that the AMP F4-BLT carbon is still the best XC racing fork ever made too. This SR fork is just right for what it is designed for, commuting.

I’ve been riding on a swing shock for a while now and can assure you that this is not the case, the breaking force against the fork is counteracted by the riders weight transfer pushing down / forward on the fork and the result is no fork dive and better control under braking. I would recommend them to anyone, they work exactly how you think they should.

The old AMP linkage forks may not have survived, but I don’t think they were nearly as bad as you describe. Don’t you remember other forks from that era? Certainly Horst Leitner knew a thing or two about suspension. Without his innovative AMP Research designs, full suspension mtb technology would not be where it is today.

This was done 15 years ago. Back then it was called the AMP fork and it didn’t survive. Almost no travel when you hit a bump but massive brake dive when you so much as touch the brakes.

Wheel swings (through travel arc) forward into bump(s) which will likely chatter, work against braking force and increase rake. I suspect the fork will be sketchy.

That was my thought almost, not quite the same geometry, but close enough for me to stay away. Long long ago riding a friend’s Schwinn Krate bike with the springer fork and drum front brake, I tested braking while under fast sweeping turn. I recovered from he abrasions. Braking is going to do Bad stuff to the geometry of the fork and the wheelbase, and tire contact patch. Interesting, but dangerous.

To tell the truth, I like the way it looks like very much. I highly appreciate the design. Plus such suspension would definitely help on bumpy roads. Very nice

Commuters are not pros.
I am happy with my 2lbs each 622×37 Marathon Plus tires, my bike weighs ~45lbs when going to work. I can still keep my speed at 17-19mph on average, had no punctures for the last 3 years and have a blast any time I find a stretch of trail with hardpack.
Funniest thing is that most of the time I can keep up with people doing group rides in the morning.

[...] cool concept, would look decent on a single speed set up . more here [...]
