where are my legs?

[ilovestacy]

okay so despite living in wisconsin, ive been training for some time now. about three weeks ago i changed my seat(maybe/maybe not related, but relevant) and went out for a group ride. it is not a tough one and throughout i felt great. on wednesday i went to a sprints group ride, and whereas im not normally winning, i am competitive, this time i was not. my legs felt incredibly stiff, and solid too. ever since i have not had much in me legs. the quads feel tight and solid, but not strong and powerful. could this possibly be a seat thing or what. also possibly relatedly, i have been having pains in my knees on the front of them. thanks yall.-pc

Some times knee pain is related to your saddle height.

Saddle position (setup) can also create knee pain.

How far forward the saddle is, is determined by the length of the bike and your proportions. You want a blum bob to start at the tibial tuberosity below the knee and fall directly through the axle of a pedal at 6 o'clock.

Seat post movements also effect this position as your hips are moved.
