How to identify a Colnago Regal

In the early 1980’s Colnago began experimenting with crimping main frame tubes to increase stiffness. In the mid 1980’s, Colnago and Columbus developed the ESACOLNAGO tube which was a round tube with six distinct symmetrical flutes. In 1986, the Colnago Regal bicycle was the first bike released with this tubing. In addition, the Colnago Regal was built using the same decorative lugs as used in the Colnago Arabesque. The Colnago Regal was essentially the successor to the Colnago Arabesque.

Whilst the ESACOLNAGO tube profile was released after the Gilco Master profile, it did not enjoy the same longevity. The Colnago ESA Mexico was the last model to be built using these tubes and no longer featured in Colnago catalogues by the early 1990’s. The Gilco Master tube profile however, is still used in Colnago Master in 2019.

Special features of a Colnago Regal.

As mentioned previously, the ESACOLNAGO tubing is one of the special features of the Colnago Regal and when combined with the special decorative frame lugs (2 on the head tube, 1 on the seat tube), it is quite easy to identify this model. These decorative lugs were said to be crafted by an Italian bicycle manufacturer known as ‘Rauler’ and were also used in other Colnago models, namely the Colnago Arabesque and 2016 Colnago Master Arabesque.

In addition, there will always be frames that don’t quite match the characteristics of a particular model as they could have been a custom build, prototype etc. Note: forks can also be swapped between different frames.
