World Tour Tech
Over a flat 10-mile TT, at 50 kph, a saving of 6.45 W would save our test rider over 5.21 seconds compared to our previous single layer skinsuit. Put another way, as this rider crossed the line in the One TT Suit, the same rider in our previous suit would be 72.3m or 237.3ft behind.
