Cycling Weekly Verdict

The Speedwear Graphene Jersey is great at dissipating temperature quickly when airflow is good, but can also increase the rate of heat build-up initially thanks to the sleeves. For indoor use, it would be better as a vest. However, the value is good and the jersey is comfortable.

Bioracer has been a long-time maker of Speedwear, a line of performance apparel for which every watt counts. The brand has been seen in the WorldTour peloton over the years, and it’s been worn by National teams in World Championships and Olympic events. 

The brand is based in Belgium, where all its products are tested in its Protolab as well as out on the roads by its athletes.
