Colnago is a highly-respected Italian bicycle manufacturer that has been operating for over 55 years. High-performance road and track bikes are the company's speciality, and vintage frames are highly sought after in today's used market. Colnago originally produced the "Dream" frameset for use with road components, but its latest incarnation is a Pista (track) racing model.
Frame and Fork
Colnago's Dream Pista frame is handcrafted from Aircraft Aluminum which is double-butted at joining points to maximise strength and rigidity. Top and down tubes are oversized to maximise the frame's response in track and velo-style environments. Track-style horizontal dropouts adorn the frame's rear triangle. The frame arrives with a Colnago brand Street Pista fork, which is designed for the track but will perform well on smoothly-paved roads.
Headset and Seatpost
Pista framesets are built with precision in mind, so the Colnago Dream will only accept headsets and seatposts of a certain size. Headsets of 1" and seatposts of 27.2mm are required for this frame.
Bottom Bracket and Weight
The frameset's bottom bracket is measured at 70mm and has Italian threading, which is different from typical British and ISO (International Organization for Standardization) 68mm bottom brackets. Thus, new or replacement bottom brackets for the Colnago Dream should be of an Italian make or have right-hand threads. Without wheels or installed components the frame weighs in at just 1250 grams, or 1.25kg.
Dimensions and Geometry
The Colnago Dream is available in a size range from 52cm to 62cm. To illustrate the frame's geometry, the following dimensions are from a size 56cm frame. Seat tube length is measured at 560mm (56cm), top tube length at 550mm (55cm), head tube length at 148mm (14.8cm) and chain stay length at 408mm (40.8cm). The seat tube angle is measured at 73.3 degrees. All frame sizes accept 700cc wheels.
