How can I determine the model year of my GT Talera bike? The serial number starts out as CM17F5
Assuming you own it, try registering the bike on the GT website at http://www.gtbicycles.com/can_en/bike-registration
You'll need to provide contact info of course.
To find the year of a specific bike, it is sometimes useful this site: https://www.bikepedia.com/Year.aspx?search=gt%20talera
However, a certain "bike year" can be different for different countries, spec's can be different as well.
