I'll give you a hint. He is riding on a custom colnago cyclo-cross bike kitted out in parts just as nice as his daddy. Oh, and another hint...photo was taken just before 2007 Belgian National Championships.
Earlier in the day he was breezing around the parking lot practicing his mounts and dismounts. He looked smoother than most adults who race the sport!
Photo was taken at Asper-Gavere, BEL Superprestige Event back in November.
