Marinoni's Columbus Brain model, circa 1999, was the Ciclo. Brain was an advancement over the previous generation SL, in that the tubing was generally thinner but TIG weldable and offered in options that included oversize and non-round versions. The oversize and non-round tubes compensated for the loss of stiffness due to the thinner tubing. Circa 1999, I would expect TIG welding and oversize but round tubing on a Marinoni Ciclo.
The Ciclo was a randonneur style model in that it had rack mounts but did not employ cantilever brakes. It was designed for long, fast, day rides and was typically fitted with a triple crankset. Like most Marinoni models, it was available with a selection of Campagnolo and Shimano groups. Shimano 105 of this era was a solid performing mid-range group and MSRP for a 1999 Ciclo with Shimano 105 was $1980 CDN.
Fair value will be highly dependent on cosmetic and mechanical condition and, to a lesser extent, location. Assuming good, ready to ride condition, typical fair pricing would be around $550-$600 CDN and up to $700 in larger, hot markets, such as Montreal. Finally, be aware that the SPD-R pedals require cycling shoes with dedicated cleats. This will require a further investment for the proper shoes or replacement pedals.
