cool.. based on the name and components i'd guess it was a lower end bike not intended to be taken off road bike

spencewine

Yeah, I think you're probably right. I'm pretty sure it originally came with slicks by the same name, the last owner must have changed it for knobbies. It would make a heck of a commuter (double eyelets on the rear drop and fork and a rack braze-on), but turns out it's too small for me. As a bonus, it's got a really nice Selle Italia saddle on it.

That Campy group looks like Record OR from the early -mid 90's to me....

1988 Klein Pinnacle
I can practically guarantee you this bike has never seen a mountain trail and likely never will.
Some pics aren't the best as the Vibrant Flare paint job photographed poorly in the bight sunshine.








This Klein is built up with 6-speed Shimano Deore XT (M730) components, with the rear U-brake being M731. The components have primarily 1988 date codes, though the shifters, front brake and front derailleur are dated 1987, the first year for the Deore XT M730 group according to Shimano history. The crankset is a bit of an anomaly with a Dec 1986 code; perhaps an early run of the '87 model.

^ pretty sweet

"were mounted on a Huffy with Cannondale decals on it"

interesting. did you take a pic of this undercover huffy?

gioscinelli 

I thought it was the Record OR. As you know Campy did not label their component groups, most of the time. Thank you, Mike

Slammin

Congrats retofit nice find.

Headset: Shimano (it is if its original: Deore XT)

I'm becoming a bit of a Pinnacle sleuth and can tell you for sure that the Cook Brothers stem tell me it was either changed, an upgrade, or add on at the dealer. The stock stem is a Sakae with roller guide. The fork was a custom job as well, stock fork was chromed. Its a 22" frame the largest size. The serial number will tell you what year, whether it was an 88 or 89 for sure.
I just love the color, as it get older it fades.
Here is mine in an 18"

No, but it is still over at the shop I work at as I am repairing it for a flip so I will try and get a few of it.

1990 Moulden Custom XC... freshly powdered and built back up this am.

Was originally built with XC Pro and still has the grease guard headset, I have an XC Pro bb I will install, and the modern drive and drop bars were my changes to the bike as it came to me as a frame and fork with a few bits attached.

Before... with the original and badly degrading paint.



Now... I am getting new decals made in Black Scotchlite as to retain the new stealthier look.



Curbs out at 23 pounds nekkid.

gomango

Very nice.

Love to have one at the cabin, though I'd feel guilty if she was this nice.

Sixty Fiver

That Klein Pinnacle is amazing.

frantik

damn that looks pretty deadly.

how do you get it so light? I have a univega with "tange triple butted tubing" that is just under 30lbs.. I doubt the frames are 7 lbs difference.. even 1-2lbs more still leaves a lot of weight reduction elsewhere..?

Sixty Fiver

I like that... people used to say it was so pretty in blue.



The frame and fork are just a speck over 5 pounds... it's built like a road bike with a mix of Ritchey Logic and Reynold's tubes and we're talking paper thin here. When I ran it as a racked out, fendered commuter the total weight was 27 pounds and as a single speed it was 21 pounds.

I was stunned when my friend gave me the frame and fork and I could make it lighter... my seat post is much longer than it needs to be and I could run much lighter tyres although I would want to retain the higher volume as on higher psi tyres this bike delivers a very harsh ride and this was one of the reasons my friend passed it on. On 2.0 tyres at 60-70 psi the ride is excellent and is still very fast.

The powdercoat is also lighter than the original enamel... a good number of factory finishes can add almost a pound to a frame and a Univega probably came with a pound of paint on it.
Older racing bicycles often get a single light coat of paint to shave off a little weight.

My Kuwaharas have triple and quad butted frames and one would think they should be a little lighter... until you see how well finished the frames are.

Despite that the bike is very stiff and extremely responsive... Jim Moulden was notorious for building some of the lightest mountain bikes as sometimes he really pushed the envelope when it came to using the lightest tubes possible and much of the brazing is very minimal. He came from building road racing bicycles with Proctor Townsend and applied some of that to his mountain bikes.

Am not sure what the exact tubing mix was although some have sold me he used 753 and know they were certified to use this so I might have some 753OS mix which would explain how light the frame is although this was never suggested for filet brazing.

A lot of triple butted tubing has rather thick walls and is relatively heavy... it came in many grades so that does not mean the tubeset on the Univega is light. The quad butted mtb tubes on my Kuwahara Cascade are touring worthy while the 022 Ishiwata quad butted tubes are crazy light.

frantik

I guess maybe there is that much of a difference in the frames.. doesn't sound like you've "weight weenied" much else

actually, it's got a "smoked chrome" finish.. bunch of pics posted one page back https://www.bikeforums.net/showthread...1#post14845868 It used to have clearcoat on top of the chrome but that went along with the auto body paint the previous owner covered the frame in

they are definitely lighter than the Tange Infinity MTB and Tange MTB tubes of my other mtbs.. Univega started using Prestige MTB tubing a year or two after mine was produced.. I'm guessing this is somewhere in between.

gomango

I've commented on this one before, but she would be an almost perfect bike in the BWCA for me.

Well done.

Sixty Fiver

I love that bike... bet the chrome adds a little extra if it has been well done and is not as paper thin as many newer chrome finishes.

I wasn't trying to weight weenie the Moulden but did use some nicer parts... the wheels and crank are at the lighter end which makes a lot of difference and it's the frame and fork that really make a difference. Those Hurricanes are wire bead and if I went to the folding version I'd knock off 150 grams, cutting the seat post down will save a good amount of weight, but there are not many other places to save weight unless I invest in some carbon.

My Rocky Mountain Blizzard has a Reynolds 725 frame and weighs 25 pounds with a 3 pound suspension fork and when it is running it's lightweight folding tyres... the Moulden frame is noticeably lighter and the use of the OS steel tubes makes me think Moulden used 753 in the top and down tube with a Ritchey Logic seat post, standard head tube, and a mix of heavier chain stays and lighter seat stays.

In it's day it was one of the lightest bikes one could buy... now they make full suspension bikes that weigh 24 pounds or less.

Sixty Fiver

Thanks.

As an aspiring frame builder I am always looking at bikes and their design particulars and have a customer (who has taken the Moulden for a few spins) that wants me to build him a close copy of this bike, albeit with some slightly heavier tubing to support his larger size with a fork with dropouts that will support a fender and full rack and fender mounts ion the rear.

I figure this is more than do-able and he wants to use it for off road touring and expedition riding.

Liberated this bike from a basement and sold it the next day at a swap. Buyer thought it was a Jeffery Richmond bike. I don't know. It was a custom frame, lugged and filet brazed. Steve pots stem, Specialized 180 cranks, Suntour beartraps, all xt components, Phil Wood hub laced to Araya's, Campy headset, nitto bars, diacomp brakes and Paul thumbies. Way to big for me, but it rode like a Caddy. I put a 5'8" friend on it and he looked like a child... ha! Had nice pin stripe and was labeled 'Ridge Rider'.

Drag

My 1991 Cannondale M800 which has been built up a couple times over.

frantik

wow would love more info on that.. high end components and frame construction it looks like

Sixty Fiver

Frantik... At first glance I would have thought this bike may have come out of our shop... once upon well before my time we made mountain bikes here and still make that type of stem, and the size is certainly right as we do a lot of large builds and just about everything we do is filet brazed.

The workmanship looks great... had to send a picture to the boss as I think he will like it.

Am always intrigued by builders form this era coming up with similar and nearly identical ideas at about the same time... the stem and early PW hubs were something Arvon was building before he even knew who Steve Potts and Phil Wood were.

Arvon once told me that the first time he saw a PW hub he thought someone had copied his design.

Chris Chicago

that has to be the biggest mtb I've seen.

Sixty Fiver

I sent Arvon a picture of the bike because the more I looked at it the more I thought that this could very well be one of the very few Arvon built mountain bikes in existence... we have one example at our shop that was never sold and the work is very similar. The size of the frame, stem, Campy headset (Arvon's favourite), and the style of brazing is what I see here all the time (we like the tubes just flow together) and the fork would also be custom built with what looks like double crowned Reynolds fork.

Fast forward... Arvon e-mails me back and says yes, this is one of his.

That is probably an Arvon stem on an Arvon built frame that he originally built for someone in Calgary Alberta many years ago... he said it has been repainted from it's original.

There are only a handful of Arvon built mountain bikes out there and when I say a handful, I am being literal and this makes it a fairly rare bike so you if you contact the buyer you can tell his what he has.

frantik

wow, i said i wanted to know more info, and you delivered! pretty cool..
