Gnutti Cycle Components

Not much seems to be written about Gnutti Cycle Components, here is an extract from 'Classic Lightweights' written by Steve Warn:-

Gnutti Components

Author:- Steve Warne


Not much appears to be written about Gnutti Italian components but since many British lightweight cycle makers used their products extensively I feel that they are worthy of some study.


Carlo Gnutti established his business in 1920 manufacturing parts for agricultural machines from a factory (presumably in the same location that Gnutti are established today) in Maclodio near Brescia, Italy. During WW2 they were concerned with armament production. The manufacture of bicycle components commenced at some point after the war and continued until the early 1960’s. Today, Gnutti Carlo S P A are an engineering multinational company with manufacturing facilities in Italy, USA, India and even here in the UK.
The range of bicycle components comprised chain sets, hubs (and q/r skewers), bottom brackets and head sets. The earliest advertisement that I have seen for Gnutti components is from October 1949.
A number of lightweight cycle makers quickly adopted Gnutti components, including Claud Butler and Holdsworth. It would seem that these parts tended to be used on higher end machines, presumably due to cost. In the 1951 Claud Butler catalogue the most expensive machine (Massed Start Model) had a Gnutti Decagon head set, a Gnutti hollow bottom bracket and a Gnutti chain set. F H Grubb used Gnutti chain sets on his top of the range ‘Perfection’ model in 1949.

Gnutti High Flange Hubs

Acquired a set of NOS Gnutti hubs. Think they are 1960’s as they stopped making them around that time and they have the last design on the QR Levers.
I would say not as good as Campy but interesting all the same. These have never been laced. I have dismantled checked, cleaned and repacked and adjusted bearings. Cups and cones showed no signs of use, ie: no tracks. Now to decide what wheels to build.

Sorry about the late response
Very interesting hubs. You are quite correct in that the skewers are of the later type. I am curious to know if the hub shells have the Gnutti name engraved on them anywhere. I have never seen large flange Gnutti hubs and suspect that these are not Gnutti and simply have Gnutti skewers. I have researched Gnutti further since I wrote the Classic Lightweights article and there is still much to learn. Sadly, my attempts to get cooperation from Gnutti in Italy has failed so far (they are still in business - but not cycle components)

Thanks Your reply/comments: I did see a Gnutti Advert somewhere that showed Gnutti Low Flange Hubs but stated they also provided Hi Flange Hubs.
These Hubs are made in the same way as early Campy hubs with Chromed Steel centre Section with Pressed on Alloy Flanges though not to same quality of finish.
The centre sections are stamped 'Made in Italy' but no Gnutti name on them that I can find.
I still believe these to be Gnutti but if anyone can prove me wrong I will accept it.

Not possible to prove a negative wrong. However, I have 'Cycling' almost complete from about 1945 to 1960 and i have never seen an advertisement for large flange hubs. I also have sales material and although there are pedals and freewheels listed there are no large flange hubs. However, I have learned a little more about Gnutti cranks recently that I was not aware of (different grades), so I am open to persuasion ! I should point out that all of the small flange Gnutti hubs that I have seen carry the Gnutti name of both the barrel and the flanges and i can see no reason why they would have used different barrels for large flange hubs - makes no sense as they would be the same specification. Sadly, despite my repeated requests GnuttiCarlo in Italy appear not to be interested in opening their archives to me ! They made bayonets for the Italian military in WW2 !!
