Tom Danielson has a good shot at making Garmin-Cervelo's Tour de France squad after his performance at the Tour of California. He recently brought his time trial bike into fit specialists Retul to get it dialed in for the rest of the season. Retul uses three-dimensional motion capture technology to fit riders while they're in motion, eliminating the guesswork behind many traditional fitting methods. This wireless LED harness allows Retul to track position and motion at multiple points on the body. -
Retul's software maps a rider's position. -
Tom Danielson brought both his road (Cervelo S3, shown here) and time trial (Cervelo P4) bikes in to Retul so his biomechanical and fit coordinate data could be recorded. -

Danielson all wired up on his P4 time trial bike. His saddle was raised 5mm, helping to open up at the ankle and rotate his pelvis, improving power output. -
Opening up Danielson's ankle was a priority. He had been dropping his heel in an attempt to maintain a good knee angle despite low saddle height. -
