Best choices for that kind of engagement are Industry Nine, Chris King or a White Industries Trials Freewheel (only available in 18t). The Hadley's, DT 240s are great, but if you are saying instant, Industry Nine are really your best choice.

The WI freewheel option opens up your choice of hubs.

That's how they sell 'em, but you can mount other sized WI cogs (17-22) to the trials body/driver and rock 72 points of engagement.

I've enjoyed using my hope ss/trials hub. It has 48 points of engagement, which may not be instant but its close enough for me. White Industries trials freewheel is another great option.

The True Precision Stealth hub has the only truly instant engagement system that I know of right now in production (roller clutch). The only thing I don't like is the proprietary cog interface, but you can always use the cassette hub version as an SS.

Where does one find the information on how to do this?

I had been using WI freewheels for years before I got the itch to try this.

I ordered the trials freewheel from my lbs. Larger cogs with a new bearing pressed in can be ordered directly from white industries. If you use the instruction below, you will reuse the seal, so take care removing it.

Here's the instructions I got from WI on how to disassemble the freewheel for bearing or cog replacement.

"You can disassemble the
freewheel by using a red handled Park pin wrench. Locate the pin
wrench in the pin holes on the red locking ring and turn to the right.
The locking ring is reverse threaded so turning the lock ring clock
wise loosens the ring. Once the ring is off the driver can be pushed
out the back towards the blue seal"

(I seem to recall I popped the seal out at some point prior to this). The driver is what you need. Once this is out, follow the reassembly instructions to install/transplant it into the new cog body.

WI instructions continued.
"Check the internals and clean the
freewheel. Apply tri flow or a light oil to the pawl and spring
pockets. Check the bearing and see if it feels smooth. If the
bearing feels rough, then it should be replaced. To replace the
bearing remove the C clip retaining the bearing. Pull the bearing and
repress a new bearing in its place.
After pressing the bearing into the bearing bore, reseat the C clip
and insert driver unit. Lastly, carefully install the locking ring
tightening it in place with the pin wrench, again, remember that it is
a reverse threaded lock ring. Now press the blue seal in place at the
back of the freewheel."

The White Industries cassette hubs are pretty nice too. Not quite as "instant" as a Chris King, but pretty damn close and about half the cost.

i have the hadley 72 pt on one of my single speeds, and some hadleys and chris kings on my various geared bikes. i really don't see any difference once you get beyond 72 pt engagement. Hadley had some 108 pt engagement hub options for a while but they had issues.

if you go Hadley, make sure to order it in the 10 mm thru axle version rather than the 'standard' singlespeed version they usually ship (which uses a very heavy solid axle, with end bolts).

Absolutely super smooth, silent and INSTANT

Sadly broke two of them in less than a year. In only what I term moderate riding. Seems like they went out of business after that. If they are back, I hope they made a much better seal for the engagement than what I had. It could tolerate NO water on it. Um, perhaps I should disclose I live in SW Washington, it rained here once...hasn't stopped yet. I took the second one apart after no one responded at True Precision, yep, nice roller clutch, machining on all parts was spectacular, as others have noted, something that rewards when fondling...but water had gotten past the little "seal" and rusted up the rollers, races and roller cage. It would slip under only moderate pressure (running 32:18 on a 26r)

I ride mostly fixed gear now, the True Precision is THE closest to riding fixed but with the ability to coast. Absolutely amazing and sexy/silky/smooth.

Too bad mine din't hold up
YMMV

The True Precision hubs are probably the most true 'instant engagement' hubs on the market right now, and the coasting mechanism is totally silent, which is bizarre. Pricey, but super well made. My shop has one that I fondle a lot, and wish I could afford...

He was at the Toronto Bike Show a few weeks ago. Had a set of very nice looking/feeling hubs - caught my eye since I had not heard anything from them in a long time. He said they had some early issues, but stands behind their warranty - you should drop them a line. I'd like to know, since I've been tempted to pick one up...

Peter at Misfit got all hyped up on red bull and skittles, and wrote about those true precision hubs. I'd tell you what he said, but sometimes I just can't decode him. This is one of those times.

yes.

translation:
superficially good, great even but incredulously expensive.
no long term testing completed.

i break everything.
last year 2x american classic, 1x wtb and 1 ENO...but it had it coming it was 2 years young.
