Conversion: Palo Alto to Masi

No reason I had to do it, but I saw the Masi Gran Corsa frame that brian3069 was selling here, and decided I wanted it for my “daily rider”. After a lot of questions — Brian was very patient — I bought it and it has been here a couple of weeks. I hope to swap everything over soon from my 1980 Palo Alto (mix of Campagnolo and Avocet components).

A few changes are needed to get it on the road. The biggest is the frame is set up for a 126mm axle, every bike I’ve ever had has been 120mm. So I needed at least a new rear wheel (and my existing rear rim was developing a crack, so…). I found one on “local” craigslist in a nearby city, looked decent; sent him a message, after three weeks, I gave up and bought another set from eBay, and told the first seller I’ve moved on. He finally responded, with 4 words: “You are f——— pathetic”; wow, glad I did not get into a transaction with him! And that wheel is still listed on Craigslist, sheesh. Anyway, wheels might arrive today, the description was: “Atom low flange quick release sealed hubs with Simplex skewers, Sachs EY 13/28 tooth 6 speed freewheel. 36 spokes laced to Mavic Module-E doublewall eyeleted 700c 622 mm BSD clincher rims drilled for presta valves. Hubs measure 98/126 mm over the lock nuts”. Well, sounds nice even if the hubs are not Campagnolo.

Hoping that most of the stuff swaps over. A few things I have not thought through: (a) seat post diameter, both frames are Columbus, but…??? Should have checked. (b) I see a slight recess on the back of the fork crown and the frame’s rear brake bridge — recessed-nut brakes? Can I adapt? Rather not buy all new stuff at this time, the current Campy brakes work well enough for me.

The wider axles means more cogs, which will be a new experience for me; the wheels come with 13-28 6 speed. Hmm, will the Nuovo Record span all those cogs? Short term, don’t really need the 38T anyway. Might consider a newer Campy RD later, should check online which ones might work, I don’t mind the looks of the black/silver one newer than a NR. Might be contacting PastorBob for 6/7 speed narrower freewheel eventually, maybe 13-24?

I plan two stages. (1) get the bike on the road now, and enjoy it, using as many of the parts swapped over now. (2) an eventual re-paint and aesthetic re-fresh, thinking of doing the handlebar tape, cable housing, et.c, in yellow. In between, the problematic Avocet cranks may go away, I need to join ($) so I can place WTB ads in the For Sale sub-forum.

BTW, been looking online a bit, plus I measured. The frame needs, flat surface to flat surface, 1/"2 on the rear brake bridge and 1-3/16" on the fork crown to mount brakes, and both of my old brakes have plenty of bolt length; but the opposite-the-caliper hole is a bigger diameter on the Masi. I did a Goggle and found a post on another forum about swaps (apparenently it's usually the other way) and mentioned "get those plastic thingies made for the purpose", I presume a plastic bushing with a small flange. Alternatively, I see some places sell replacement recessed nuts, like Problem Solvers -- I could order a pair, cut to desired length and drill out the threads and make my own (Ti? ) bushings.

Glad you took that Masi off the table, it was going to really muck up some other already really mucked up foolishness.

Same here.

I'm looking forward to the build!

It's really pretty, I'm excited about that first ride. Already looking at Masi jerseys on the internet. The wheels from eBay showed up right after I posted, they look great except the spokes are not chromed or SS and will need some polishing.

Reference to a guy here who "converted" a Free Spirit into a Masi. A "Breaking Away" tribute.

A Trek was trans formed into a stunning replica and a stellar melee ensued.

... with13-28 6 speed... Will the Nuovo Record span all those cogs?


Yes, usually. And even a 7-speed...

Try to keep the chainring difference around 10t if you want to use the NR RD.

Thanks -- like most things on the internet, it makes sense once it makes sense.

Cool. Right now the chainrings are 42/52, and I think I've gone down into the 42/28 1st gear perhaps twice in two years. Eventually, I see either leaving the chainrings those sizes and go to a 13-24 freewheel, or leave the sprockets alone and narrow the chainring span to, eh, 45/52?

I got lucky on one thing; I held the bike up to the car and Porsche Guards Red looks really close; so I hit a hobby shop and got a bottle of model car paint in that color. After a little clean-up and cleaning up the scratches and pockmarks, I applied some. Really close! Again, no substitute for a complete re-paint, but OK for now.

Well, a setback. I got the wheels out and the hubs felt like gravel had been substituted for bearings. Two cone wrenches later, saw these were not sealed bearings, bone dry in there, didn't even bother breaking them down to examine the races. Contacted the seller, he's doing the right thing and taking them back, apparently an accidental mis-description on eBay. $$ to ship back, how does BikeFlights work?

Well, Friday I'm driving perhaps 75 miles round trip to see a guy with a set of wheels on Craigslist, both hubs and rims are Campy, sealed bearings this time, in the same price range. Seller is even checking to see if he has a freewheel broader than the 13-19 (yikes!) 6 speed that's on it now.

Which 'Masi'

Masi of Italy, had shifted frame making to California for the US market, nice steel, lugged frames..
in the 80's

Probably one of those...

more recently you see the logo on welded aluminum and steel framed bikes

from the large Pac Rim OEM contract factories ... names being a commodity.. to resell .

so the latter 2 , (and likely your red one), will be not Italian standard threaded BB,etc.
But (near universal ) British..









...

Been thinking about this - any reason I cannot simply buy some of the "nuts" for recessed-nut brakes and bore out the centers to admit the brake shafts (apparently plenty long enough) to use as a "centering bushing"? Any pitfalls here?

Got them home, beautiful even if the rims (apparently never used after the wheels were built up) are what I'd call semi-aero, a bit modern for my tastes but it is a late-80's frame after all. The rims have one sticker that says "Campagnolo", and another that says "Moskva 80"

The wheels came with tires, Continental Ultra 2000 in 23mm, they've clearly never touched pavement. Looking on-line, over 10 year old type IIRC, should I simply discard?

They sell adapter bushings. The disadvantage of drilling out nuts yourself is that if they're stainless they're hard to drill and you need a cobalt bit or similar. If they're plated, you're still drilling through chrome, and it's raw steel under the plating. Coming up with a way to hold the nut for drilling can also be a challenge, and while I've done it, I wouldn't consider the things I tried satisfactory methods.
