Rui Costa's chainring failure at the Tour de Romandie prologue earlier in the week was down to the use of incorrect chainring bolts, not an equipment failure, Cyclingnews can report.
Lori Barrett, the Managing Director of the team's chainset supplier, Rotor, contacted Cyclingnews to share information and an update from the Intermarché-Circus-Wanty team on the mechanical issue.
