The 1981 Moseman
The bicycle for this ride is a 1981 Moseman road bike. Rodney Moseman, in a gracious email reply to my queries, sent along some essential information. The bicycle was built as a basic road racing bicycle. As such, it possessed, and still does, most of the influences of that time. Among them were a growing use of lighter weight elements as well as a more generous use of braze-ons. One significant influence or trend that distinguishes this bike is the large oval fork.
The following are specifications as the bike will be configured for L’Eroica. Look to posts on the main page for some of the current conditions that are being changed. I’ll post more photos that will satisfy the hungriest bike geek.

Components
The components are Campagnolo with one exception noted below, though not a unified Gruppo. The original wheels were built before the bike was built and assembled. There is a mix of Super Record and Nuovo Record components. The reason for the mix is lost to my memory fading over 30 years.
Hubs: Campagnolo low flange (see wheelsets for drilling)
Derailleurs: Campagnolo Nuovo Record rear. Dura-Ace front derailleur attached via braze-on
Shifters: Campagnolo Nuovo Record fixed to braze-on bosses on the down tube
Crankset: Campagnolo Super Record, 52-42, 170mm crank arms
Bottom Bracket: Campagnolo Nuovo Record
Pedals: Campagnolo Nuovo Record, Super Record toe clips
Seat Post: Campagnolo Super Record, single bolt adjustment
Headset: Campagnolo Super Record
Brakes: Campagnolo Nuovo Record
Stem: Cinelli
Handlebars: Cinelli
Cables, Cable Housing: Campagnolo
Saddle: Brooks Team Pro
Seat Binder Bolt: Campagnolo
Wheels: Hubs as above. 3 wheelsets:
Original: Ambrosio Synthesis tubular rims, 36-hole with Trois Etoiles double-butted spokes 15-16-15 laced 3-cross.
For L’ Eroica: Mavic Open Pro, 36-hole with DR double-butted spokes, 15-16-15 laced 3-cross. The rims and spokes replace the original wheels.
(The “L’Eroica” wheels will be my normal wheels to ride most of the time. Alas, I have given up, mostly, my fantasies of riding on tubulars, though I still have plenty of them and will bring out the aero rims when rides permit. The tires for the new wheels are Continental Grand Prix 4 Season, 28mm.)
Additional: Ambrosio Elite 19 Clincher rims, 36-hole with DT straight spokes laced 2-cross.
Time trial wheels: Araya 1 aero tubular rims, 32-hole rear, 28-hole front, DT spokes. Rear laced 3-cross, front laced radial. (A sweet set to ride and one that helped shave :30 off my best 10K time trial)
I’ve gone through too many tires to mention and have tried quite a few including Clement Paris Roubaix and other Clement tires, cheapos of all kinds, Vittoria, Barum (for the time trial wheels) and probably a few others I don’t recall.
I have same arsya aero 1 setup 32h rear 28h front.want to use on road bike thinking schwalbe ultremo ht 22.
You said you went through a lot of tires what do you think would hold up best ?
James, I went through a good many tubular tires over the years. This set up is with 28mm Continental Gatorskins and they have been great. I run Conti 4000 S on my carbon race bike and like them, too.
