Scored a cheap marzocchi Roco the other day. Appears to be an "RC" with a chrome shaft and rebound and compression adjusters. Before I mess around with it too much, I'm looking for help on specs. I measure about 2" of exposed shaft, and a 7.875" eye to eye. All I can find about the Roco says 7.875x2.25, but that was kind of pre-internet. The shock works surprisingly well out of the box.

if there's only 2" of exposed shaft, then it might be the 7.5" i2i

yeah but it's not.

 

[jonKranked]

yeah but it's not.

ok. i mean its possible it was an OEM variant?

 

[jonKranked]

got pics?

I had a longer Roco WC on an Iron Horse 7point. I remember liking it?

I didn't like the 74HA on the 7point.

I was about to score one really cheap before buying the Suntour TriAir. I've found the exposed shaft is shorter than the advertised travel according to emptybeer and other sources. Trust the E2E rather than the shaft and look at the advertised combinations at the poster @jonKranked pasted above.

7.875 x 2 was another common size BITD

I ain't no scientician, but that looks like 200 and 50mm to me.

Was it for rocos? I see plenty of other shocks, but not many of these. It came with a 2.25 spring on it but that doesn't really matter

Even pinkshirtphotos takes better pictures than that

What bike is that? Sunday?

Anyone notice the typo?

i new someone would spot that

Take the shock off the bike. Remove the spring and spring retainer. Now measure your exposed shaft.

about as close as you can get without getting sued

it's the BMC

look, take a chance on the notion that I may not be completely retarded.

I measured the eye to eye by drawing a point in the center of each eye then measuring the distance.
Then I compared it to my X2, identical.
I put it on the bike- fits like the X2.

I then removed the spring and retainer and measured the exposed shaft with my calipers- 2". Actually more like 1.99.
Then I measured the exposed shaft on my X2 (2.3") and my RC4 on my DH bike- 3.02".

The exposed shaft is 2", or very close. It is not 2.25" unless there is hidden shaft somewhere or the shock body goes over the aluminum shock eye that is screwed onto the shaft (it doesn't).

The hangup is that I am seeing the exact same infographic you posted above (I can google too) and am not seeing a 7.875x2.0" size, so I want to see what's up before doing much else with it. I've never owned a roco, but somebody somewhere may have an old porno/marzocchi catalog that they can look through.

I know Marz didn't advertise it, but that size was very common on bikes of a certain era, and since you clearly HAVE a shock in that size I'm guessing it was an OEM for some other brand.

Just a longshot thought...

Reach out to DVO - Bryson Martin may be able to answer your question as he was a big part of Zoke US, and if that does not pan out, - don't laugh too hard - Contact Fox, they bought the Zoke IP and all the spare parts. Somebody there may have a clue.

i'm just busting your chops. i'm also assuming you included the portion of the shaft underneath the bottom out bumper in your measurement.

ook, take a chance on the notion that I may not be completely retarded.

i always operate on the assumption that most people, myself included, are at least partially tarded

well, the bumper crumbled and fell off due to old age, so I think I'm good.

I'm sure that bodes well for the condition of the various seals in the shock.
