Cervelo rolls out new bikes at Flanders
Cyclingnews photo-reporter Chris Henry spotted these stealth bikes in the CSC pit area at Flanders over the weekend. Interrogation of Cervelo main man Gerard Vroomen reveals them to be Cervelo’s new all-aluminium R1 road bike which fits into Cervelo’s range “below the R2.5. It is an aluminum frame that is built along the same design parameters as the R2.5. So it is optimized for stiffness-to-weight ratio.”
The protos were delivered to the CS team just last week and were ridden in Flanders by CSC riders Lars Michaelsen, Tristan Hoffman and Thomas Eriksen. Fortunately, CSC’s mechanics have prevented us from making lots of sad Spinal Tap ‘none more black’ gags by using white handlebar tape on these protos. No word yet on availability, though we’d be surprised if it’s before 2005
