And it worked fine. No surprise. The instant engagement is more subtle than I expected, but then my other hubs have been pretty quick engagement units too (Novatech SS hub and SRAM dual drive 3-speed disc hub). It really came in handy on slow corners and wheelie lifts over dips. I'm very impressed with the 18t cog. It is a thick, beefy unit that is showing no shark-toothing (as compared to a steel King Kog, that started showing wear on the first ride). Conditions have been very wet, we just had 2 days of rain, in AUGUST!
Oh, and I like the 2.3" Gazzi D/H tire better than the Core. It's more solid on the rim at very low pressures than the Core. Noticeable difference. And the 3.0 Gazzi just can't be beat. ran pressure today soooo low that I could contact the rim just by lightly jumping on the handlebars. Did the usual ramming into roots and rocks, ringing the rim, never a pinch flat.

Oh, and for Shiggy and Brandon and Sparti, those Avid's I had on at the Ride Fest? They were Road brakes. written right on the sticker on the caliper, no wonder they didn't set up very well! lol. Thor got my MTB set to me this week, put them on and they work great. Just need different levers. Hope to have my HOPE's rebuilt soon and can put them back on the reBrew, dang crackheads.

quiet time

It really IS silent.

I don't know how they do it, but it doesn't use pawls and steps or a ring gear. Maybe some kinda roller clutch. But it is instant and silent. Kinda like riding a fixed gear, but with coasting.

view of the proprietary cog and spacers. exquisite machining work.

assembled hub sans torx screws holding cog on

different view

Another note about the cog, it has tall teeth and so tracks the chain better than the flat-topped cogs like the King Cog or what you pull off of a cassette. It is thicker than even a DX cog. I like it!

Sachs did this before 1950. I don't know if its the same mechanisem. I will take a picture next time i take one apart.

One of my riding buddies

has been riding the stealth hubs for two years now, and has had no reliability problems at all. He's got a funny set up, though- his Titus CXR ti SS weighs in at 38 pounds in its current configuration...

And Sun / Ringle / Whoever-the-hell-they-are-now had a silent hub in the early 90's. Used a roller clutch, IIRC. Everybody I knew who had one loved it... until it blew up. And every single one did. Road bike, Mountain bike, flyweight climber, clydesdale, big burly sprinter, it didn't matter. They all broke.

This is, of course, more of a comment on the execution than the idea, but I'd want to see a long history of reliability, both with the part and the company, before I'd invest in parts that use a technology with a checkered past, and proprietary parts to boot.

Just my $0.02.

Looks like I'm the test subject

I do like to try different things and I ride fairly aggressively so I think I make a good test platform. The reBrew weighs about 35# as a SS. The Vulture (when completed) may weigh around 30#, or not...

Glad to hear about a 2 year successful test so far. The hub now has about 30 miles on it in 2 rides, one in the wet, the other was dry. I'll see if I can get out during the week on it.

yesterday's ride felt GREAT, I was back in that "one with the bike" feeling, log and stump-overs were smooth and the 285 log ride...made the corner on a hop and made it up the ramp to the big log. felt smooth and in control, but loose. ya know what I mean?

Now to just get into some kinda shape so I can show those 'geners that I don't always have to be last...

Check out True Precision's website at http://www.trueprecision.net. They explain how they work and stuff. You can also order them direct. I spoke with Mean Todd at Webcyclery and he said he'd be happy to order them but in the past they had serious supply problems. However, I know True Precision has been updating their hub line-up so I think that may have had something to do with it. Also if you do a web search I believe there's a few reviews of these hubs from BMX and trials guys who swear by them.

i would probably get the regular disc mtb hub so i wouldnt be limited to 14-18T cogs. they appear to be out of stock though and working on a new line. shall call to see what the story is on that.

My stealth hub cost a fraction of Precision's

On a vacation in Mammoth I broke a rear wheel and went into a bike shop and bought the only wheel in stock. Later on I noticed it was very quiet. In fact it truly qualifies as stealth, not a tick out of if. I can roll up on my SS and surprise bobcats, hikers, etc. The hub is a Shimano STX RC Parallax 85 laced to a Mavic 221. I don't know the secret to its silence (it must be ratchet and pawl??), but I would buy another!

OoooooH!!!! Details that aren't published!

Hey,

I've been drooling over these hubs for over a year now... I've got a question though that isn't published!

What is the Chain line? Yes, it's adjustable, but what is the min., max., and the increments you can adjust it to (ie. spacer thickness)?

I'm just wondernig as I've finally committed into buying and building up my first SS and want to get the chainline as spot on as can be.

Sweeeeeeeeeet!

Sounds like a Shimano Silent Clutch hub:

Looks like they've had LX and STX RC versions...

I'm not sure how to measure it, but they have full dimensions on their website. The spacers look to be about 5mm thick,

It survived a trip up Ape Canyon Trail yesterday, better than I did. lol

Mystery freehub

I thought so too until I searched for a matching hub. The R080 is larger than the typical freehub and requires a special hub body that accomodates the extra length beyond the cassette carrier itself. (Attached image from shimano's exploded view). I have a freehub that looks like all the others - only as long as the cassette carrier. It may have been yet another product that shimano dropped. The hub body is hard to find - only in Europe or special order from Sheldon Brown (maybe?).

Interesting. After reading your message, I remembered having an old shimano hub with a really quiet freehub body. So I dug it out and here it is. Way way quiet. Normal style. I found the hub it came on. Exage FH-HG50 that came on a Peugeot mtb purchased in Germany.
