A compromise could be to add the info as a note instead of placing it in the middle of the text in (), see below. This would maybe result in a clearer text impression.
Cross-country ski poles for kids and juniors with focus on speed. The Salomon Racing 10 Carbon Jr. ski poles have a great power transfer due to the added carbon in the pole structure.
The pole is made with a 16mm top diameter that narrows in at the end of the pole into 9mm diameter.
The great handle underscores the focus on good power-transfer.
Notice: The manufacturer doesn't state the amount of carbon used in this pole construction.
