Power Differences Between Road and TT Bikes
It's normal for triathletes to experience a lower power output on a time trial (TT) bike compared to a road bike, with a difference of about 10% being typical. This discrepancy can arise from changes in muscle recruitment patterns and the hip angle, as the TT position tends to engage different muscle groups. After a bike fit, most athletes can expect to close this gap within two to three months with dedicated training on the TT bike. The goal should be to ultimately aim for less than 5% difference or reaching approximately 15 watts lower than the road bike's output.
