Build thread: 1974 Masi Gran Criterium
So, to be honest, I have several "irons in the fire" at the moment - and by that, I mean ethereal bike-shaped vortices for throwing my paychecks into. My wife and I are also moving to Germany in August, and are very close to the "frantically throwing things overboard" phase of our move. For those of you that may have been following the items I have for sale in the classifieds, expect further discounts imminently, along with a drastic purging of my parts bin.
Anyway, in terms of the aforementioned vortices, there's the custom 650b all-season all-road project I'm working on with Stephen Bilenky, which I recently paid off. That's still very much "ethereal" as we also recently changed up the parameters and the previous frame drawing went out the window. A little more physical, however, is my Eisentraut Limited Touring, which I'm currently having resto-modded by Harvest Cycles here in Brooklyn, who amazingly have a nascent frame repair and paint operation in their basement. Their operation is very old school and kind of a wonder to find in 2023, especially not in a way that is insufferable and hipstery, but just a group of unprepossessing people dedicated to keeping old bikes on the road. They are just up Myrtle Avenue from Johnny Coast's workshop, who is making some of the most exquisite frames of any kind anywhere at the moment, in my opinion. Johnny is a great guy, and the rehabilitation of the Eisentraut was definitely inspired by the beautiful randonneurs he builds, which were themselves inspired by Eisentraut and Bruce Gordon as much as they were by French constructeurs like Alex Singer and Jo Routens. I just got the Eisentraut after the "modding" part was completed by the guys at Harvest and executed a very preliminary test build this past weekend before the frameset goes to paint:
The frame and fork were in rough shape when I acquired them several years ago. Clearly, this 'trout had led a long life on the road. The fit was nevertheless amazing and I knew immediately that I wanted to have it both repainted and personalized/modified for usability (this point will become relevant in a moment). Being a product of its time, the frameset lacked braze-ons for everything but the RD cable stop and cable guides on the BB. I do plan on making a thread for the Eisentraut this week with pictures of the process as well as the operation over at Harvest, as well as going more into my reservations for "butchering" the frameset and ultimately why I decided to proceed.
Anyway, needless to say, I have explicitly forbidden myself from making any purchases not directly connected to either of these projects, and was very much focused on the Eisentraut this weekend. But then I saw this on eBay:
A 1974 Carlsbad-built Masi Gran Criterium in my size - perhaps my number one grail bike. Sure, I see these listed all the time - and then sigh internally when I see the asking price. If I have had the privilege of owning some amazing bikes in the past, it's been the result of persistent internet sleuthing to find those online diamond-in-the-rough barn finds. Still, gone are the days like when, in 2012, I snagged a low-mile Colnago Master X-Light with full DA-7700 from a widow who was liquidating her late husband's bikes and was happy to take $350 for it. I've had maybe a dozen scores like that. BUT - this listing was set to an auction with a starting price of $400 - what was the deal?? The pics looked amazing:
amazing lugwork
The frameset had the lusty jaw-dropping twin plate fork crown. It was my size. I even liked the paint! The serial number on the BB also indicated that this was from 1974 and thus relatively early in the startup California production when Masi Sr. was still overseeing the operation. However, the astute Masi-aficionados out there will note that this frame has a whole complement of braze-ons that aren't original - cable guides on the TT, shifter bosses on the DT and a second set of water bottle bosses on the ST. The text of the listing was revealing here:
Alas, so there was a bit of a catch here...
But even so, I found the Masi appealing to me even more - here's a frameset that has been repaired and modified and would be perfect for a daily rider with a modern(ish) Campy gruppo to replace my current daily frameset (1982 KHS Professional) which is slightly too big for me and lacks a second set of water bottle cages. I contacted the seller, who is a wonderful collector just looking to thin his herd somewhat. He also felt no qualms, given the condition and history of this frameset, to have the rear dropouts respaced to 130mm and running modern components. We agreed on a reasonable shipped price, and bingo, I now have 3-4 days to either sell some Scheiße or come up with an impressive story for how yet another frameset has appeared in our apartment.
I'm ultimately not too worried about the steerer for now - unless I should be?? I'd also be interested in whether there are any indicators that the crash repair may have been conducted in period by Masi USA.
Anyway, I hope this has been edifying so far! I'll leave the story there until tomorrow, when I'll go into build plans!

Here are some pictures of my Masi for comparison.
(Yes, I'm also the sort of heretic who puts index components on a '74 Masi!)
Before I installed the indexed components, obviously
I'm pretty sure that's not original!
So you and I both have brazed on shifter bosses, two sets of water bottle bosses, and top tube cable guides. The metal bits for these are fairly standard, but the top tube guides are at least consistent between our bikes.
The fact that the crack extends beyond the hole that was drilled to stop it would worry me a bit, but I don't know enough about these things to say if that's likely to be a problem.

The braze-ons, seat tube bosses, down tube shifters and definitely the top tube cable guides, and the under the bottom bracket cable routing - not original.
why? When these bikes were built, all within the first 200, keeping in mind that the first 25 had a different size and numbering format, Masi was pushing to get bikes out the door.
initial production was late, no time to waste, especially with custom bits.
demand was strong.
‘it would take over a year till the “off menu” add ons were known.
as to the top tube cable guides, those are Silva design bits, they were a 1978 at the earliest component. Did not exist in 1974.
the Silver frame has a decently faithful repaint.
I happen to like the all painted fork on the white bike, other than I would pick out the region between the plates.
‘I had a Masi repainted in Spring 1975 at the plant and requested only retain the chrome on the ends.
a very practical reason, I often trained along PCH, it was a bunch of work to maintain the chrome.
I did have downtube shifter bosses added, $15. Extra. Done for ease of maintanence.
‘unfortunately that bike was stolen in Sept. 1976.

I’m trying to get my (1978?) Gran Criterium on the road. Like you guys, mine is rescued from eBay purchased “as-is” frame only with no fork. I’m not trying to keep it period correct. Instead I hope to have a versatile endurance road rider that can handle hilly club rides.
The fork is a 1” threaded Kestrel carbon fiber fork. It is limited to a 25mm max tire width. If I do get a full restoration I may commission Franklin Cycles in Ohio to build me a proper “biplane” fork crown fork in the same metallic silver with royal blue accent color.
My drivetrain is Ultegra 6600/6603/6600GS components with a KCNC bling hardware kit. The rear triangle was spear to 130mm by the previous owner. Not sure about frame alignment though. And one rear dropout adjuster is broke off & I cannot get it out. The polished Velocity Major Tom tubulars look trick but to me are not gaudy on this resto-modded build. The black accented Ritchey WCS seatpost and Specialized headset I think look good in an appropriate California custom sort of way.

Andy_K Thanks for sharing your GC! I, too, love the all-white repaint and the tasteful Campy build. My plan for the silver Masi is either a 10sp Chorus build with indexed Campy TT shifters converted to DT use (my current daily has this set up) or Athena 11sp with brifters. And yeah, your frame has definitely been modified at some point. While I'm no expert, I have done a fair amount of research over the years on this particular generation/iteration of Masi (and also looked at just about every picture I could find of these early GCs) and have never seen those cable stops routed under the BB. But, ultimately, I'm not really a purist when it comes to these things. Whatever "modification" will make a frameset or bike more usable for your desired ends is well worth pursuing. Obviously, there's a limit here to what degree of alteration is justifiable, and which is determined by taste and respect for the intent of the original makers - and these are virtues that not everyone has now, or has had over the intervening decades. The modifications on these Masis enhance their usability without altering their inherent character, IMHO. Personally, I'm excited to get my hands on a GC that has these slight modernizations and is not 100% original - that means I can ride the hell out of it every day and not feel like it should be sitting indoors immaculately restored wearing a period-correct Nuovo Record gruppo.
repechage Very sorry for your loss, I wonder where all those bikes ended up? Surely they must still be out there. Do you still have the serial number on hand? Also, as someone who actually had a frame/fork restored by Masi USA around that time, are there any indications that the repair/mods on the silver GC might have been undertaken by Masi? I definitely plan on having the guys at Harvest look at the fork steerer and get their opinion on its integrity. Thank you for sharing your thoughts here!

masi61 Loving your Masi build so far - totally agree, whatever gets (and keeps) it back out on the road! Very interesting to see that your frame has similar mods and also decal set and paint. Also wholeheartedly endorse the plan for getting a new fork made.
mpetry912 You have a beautiful GC, sir! That's my dream - to have a bike that long and build a relationship with it over years and decades and eras of one's own life. Unfortunately, bikes and frames don't seem to last much longer than a year in my pile - though I'm hoping that will change with this current crop I've got coming in!

The thing I was looking for last night was information on the additional markings on the bottom bracket. On mine, I've got an 'E' a '7?" and a couple of other marks that aren't necessarily letters at all. I'm guessing the '7' is the first digit in the seat tube angle. The others...who knows. I see several such markings on your bottom bracket too, but can't quite make them out. I wasn't able to find any information about what these other markings might mean. It could be that the explanation is lost to history.

The middle and later 1980’s under the bottom bracket guides were cast in. They had fully moved away from the Fischer sand cast shells.
those +GF+ parts required lots of hand filing to the shorelines, windows and surface. Sturdy and labor intensive.

Considering the crack that's quasi-arrested in the steerer tube, I'm considering upping the sacrilege here with this build and using one of these new Innicycle threadless conversion kits. I've been curious about these since I first heard about them last year, and this Masi project might be the perfect excuse to place an order for one.
What's cool about these is that it's also a headset assembly, and the adapter threads directly onto the existing fork steerer. The expanding plug in the steerer also applies pressure evenly as it expands, from what I understand, which could theoretically not further aggravate the crack.

A Technomic could put the wedge well below the bottom of the crack.
And being a Masi could/should also warrant a new steerer and all it entails.

merziac Hahahah, I knew this thought would cause a few boxer shorts to bunch! Right there with you on the overall impropriety of this solution, but it would be a stopgap and of course is not permanent! If I do end up liking the frameset, I would definitely get the steerer replaced and even move towards a full period-correct restoration at some point. Though, I think with the overall resto-mod direction of the build so far, pairing this adapter with a level thin-tubed steel stem and a thin handlebar would look/work great. Personally, I really hate 31.8 diameter bars.

I get it but the Technomic would still solve the whole problem quickly, easily, cheaper and completely, right now, for now.

It's kind of odd that they would have taken the trouble to switch the cable routing from over the bottom bracket to under. I've got several bikes built each way and I really don't see much advantage to going under the bottom bracket. Maybe the owner was just following the latest trends at the time the updates were done?
When I'm adding BB cable guides I just follow where the cable stop is on the chain stays, especially if the rear triangle is chromed. If it's an older frame with a clamped on rear derailleur cable stop, I drill and tap the BB and use a plastic cable guide, as it's easier and I don't know of an advantage to put them on top, unless someone specifically asks for top mount.

the fork has a lot of threading, Uncommon, Masi had enough threading but not excessive beyond. One could have the new steerer longer to allow for 5-10mm of a spacer.

A full replacement requires repaint. If you're concerned about matching paint, a full repaint of frame and fork, which can get very expensive.
I'd prefer just to graft on a new section to save the fork crown finish, but I haven't tried that yet. A TIG weld is probably the easiest way to go, but I don't TIG. A local builder might be able to do that, but forks are small enough to ship relatively inexpensively if you can find a someone to splace it.

I think Mikkelsen in Alameda Ca has done a number of steerer repairs.

Very easy to splice on (and in) a new top half of steerer tube. Can even be a used fork as a suitable donor.
Some pointers from a certified welder:
Press on your favorite crown race. Make no attempt to ever consider removing it again.
Essentially, choose your cut, below where the stem wedge bolt will be.
Make clean and flat on top, by hand is as good as anything.
Measure and cut appropriate amount from other fork, leaving a bit extra.
I almost forgot, find a piece of 7/8 inch OD tubing. (easy to do) 22.2mm = 7/8 to make a sleeve 2 inches is plenty.
Press sleeve into bottom, and weld all around.
Using best practices, machine grafted top in lathe for bevel and appropriate length.
Press new top steerer onto sleeve, triple check the overall length that I forgot to tell you to write down.
Weld all around using best practices.
DO NOT CLEAN UP WELD.
The OD will be too large to remove crown race, but who cares?
If you are super diligent I suppose you could add a rosette or two, but not really necessary.
