Is there a title that refers to the person who selects the athletes who will join the national team?
The correct title in English speaking nations is Selector. The Selectors use their knowledge of the capabilities and nature of the riders to select those that represent their region or nation. Results are important but if look up any selection criteria you will quickly see behaviour standing out as one of if not the key decider on who gets to represent their country of the elite riders. Selectors work in groups and often are made up of head and team coaches and other national federation members.

Selectors also play a role in identifying talent and bring young riders into the high performance programs offered by the national federations.

There are many hoops to jump through before being selected as a representative. Firstly a rider must be eligible this involves:


being a citizen
holding a racing licence
clean drug tests
attend sanctioned events and training as required


Once eligible selection is then based on a number of factors:


results and performances at national and international events
UCI world cup points
performance in selection trials
ability to work well in a team
would the athlete win an Olympic spot and could they go on to win a medal
technique in team races
behaviour and attitude
sport science results
fit in team composition (mainly in track events)


So in short, selection is based on not only results but a wider analysis of the rider. The Selectors still have a large role in ensuring that the national team is the best group of riders rather than the group of best riders.
