good to read tip of help

somewhat doubt you were taking .1mm per cut with an expandable blade

if i tried that with me Chadwicks they would simply bind up

can probably only take about .03mm per cut, estimate

sounds like you went slightly past OEM size, no harm although doubt anyone offers pillars in 26.5 size

from you description sounds like there was a bit of deformation caused by heat of brazing seat lug

tube set for frame hightly likely to be Falck plain gauge

pillar -

me comments about pillar markings were in reference to the Campag nr. 1044, commonly accepted launch date mcmlviii, have also seen mcmlvi - this latter may refer to the steel version

on browsing the machines shown at PeterB's was reminded that his own example of A.D. MCMLXIII came with a round rail NITOR pillar and saddle.

this, is a BIG topic

pretty much all of the Magistroni marked sets on Olmo cycles of this era are of the three-arm 116mm BCD type. nearly all exhibit the six-bolt c/w pattern where the smallest possible inner is 43T. most are without the Y-adaptor arrangement and have the inner c/w mounted directly to the outer. if you were to go with a Y-adaptor set advise to make sure to get steel adaptors and not alloy. the alloy ones are failure prone. adaptors typically made by Simplex (probably of Italy).

there are different quality levels/models including swaged. one quality cottered set comes through marked L. SENIOR.

catalogue page of nineteen and forty-eight:




Rebour rendering of design shown at a trade show of MCML. as far as is known never produced.




the fabulous Super Zenith model of 1965:




there was a period of a few years where Magistroni joined forces with Gerry Burgess (GB) of Britain and Altenburger of Germany to offer a road ensemble.

for at least four decades thought that the company logo illustrated a circus tent. wrongo! while listening to an automobile repair show on the radio learned that giostra is the italian word for carousel/merry-go-round.

production of Magistroni marked products ended 1965. there was an apparent re-org by Giostra which came out the other side with the product badges OMG, Of.Me.Ga./OFMEGA in 1966.

NB - if you elect to go with a Magistroni chainset you will want to go with Sheffield pedals.
