Fulcrum has released the Speed 25+, which claims to be the lightest low-profile disc wheels ever made.
The listed weight for the climbing wheelset is just 1,270 grams, some 15 grams lighter than the Speed 25 wheels. Of course, certain wheelsets with claimed weights lower than that may well spring to mind - we'll unpick what we believe Fulcrum's justification for this claim is further down.
