Just adding to the original question II recently did a road bike event while a few steep climbs. Felt I felt myself sliding back in the saddle to the point where when the road eventually leveled off I had to stand up and reposition myself forward Kind of felt like I was going to slide off Would.
Would you consider this normal as the body is trying to apply more leverage or does the saddle need to be raised or does the saddle need a more forward position?
