Colnago TT1 Disc Frame - Black

Colnago TT1 Disc Frame – Maximum Aerodynamics and Control for the Time Trial

The Colnago TT1 Disc Frame represents a fundamental evolution in the world of time trial and triathlon bikes. It is the first Colnago time trial bike equipped with disc brakes, a design choice that allows for complete integration of hydraulic tubes inside the frame, improving aerodynamics, line cleanliness, and overall performance.

Compared to the previous model Colnago TT K.One, the weight difference is minimal, but the advantages are clear: more powerful and controllable braking, greater safety, and increased structural stiffness, guaranteed by the adoption of through axles both front and rear. The result is a high-performance frame kit, designed for athletes and enthusiasts seeking the best in time trial events.

A Complete Guide to Bike Sizes

Foreword: Not all bike sizes are the same

Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.

Bicycle adjustment margins

Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.

How to use size charts

We've created a simple guide to help you find the right bike size:

1. Check out our size charts for each bike type.
2. Learn more with specific tips to help you make the right choice.

Size Charts: Find Your Perfect Bike

Gravel and road bikes

Sizes are based on the length of the top tube (in cm), which determines the reach of the bike.

For gravel, measurements may vary slightly due to different geometries, but remain similar.

Mountain bike

MTBs are measured in inches, based on the seat tube.

Sizes also vary depending on the type of MTB: full-suspension , hardtail or fat bike .

Children's bikes

The size depends on the size of the wheels, often associated with age:

What to do with half measures?

If you are between two sizes:

• Comfort : Choose the larger size.
• Performance : Go for the smaller size.

Final tips for choosing

1. Consult the manufacturer's instructions : Always check the brand's guidelines.
2. Ask an expert : a specialized workshop can help you choose based on your height, ideal reach and goals.
3. Test the bike : If possible, test the model you intend to purchase.
