10. Time Trial • Steep seat tube angle • Aero position with flatter back • Rotates you forward, allowing hip and knee angles to remain open. • Less stressful on back and hamstring muscles • Knees should not protrude in or out. • Line from ear to elbow should be perpendicular to the ground.

11. Best Approach • Go to your local bike shop (SURPRISE!) • Try bikes that you are considering • More than a sum of their parts • Frames, components, geometry varies • Get fit by an expert • Get refit as the season progresses

13. Saddle Height • Saddle Height • measured from center of bb to top of saddle • Heel on the pedal, leg is locked. • Formula = Inseam in Cm X .883 • Formula gets you to within 1 – 2 Cm • Variables • Leg length • Flexibility

14. Saddle Position • Generally thought that knee should be over the pedal when cranks are level. • Best set up by a professional • Saddle should be level for women • Saddle should be level to 2 degree rise for men.

15. Top Tube and Stem • Torso length + Arm Length divided by 2 +4 = Top Tube and Stem Length • Individual Comfort is Key • Flexibility as the season progresses • Frames come with stock stem length. • We provide free stem replacement ($45 value)

21. Pedal Stroke Mechanics

22. Main Points • Get the right fit (foot, leg, hip, body alignment) • Learn to use your gears • Stay seated as much as practical on hills • Develop a good cadence • NOTE—From this point on, open in “Notes Page” to read the • Key Points of each slide.

23. Foot/Cleat Position

24. Pedal Stroke Made Easy

25. Drills • Spinning classes • High cadence spin up drill • Isolated leg training • Learn to use your gears

26. Optimal Cadence • High cadence • Works cardiovascular system more • Reduces workload for each pedal stroke • Low cadence • Lower oxygen consumption • Greater workload for each pedal stroke • Optimal balance is different for everyone, experiment to see what works best for you

27. How to Attack Hills? • Rolling hills • Use momentum to carry you up start of hill • Short hills, power hard through lower portion • Shift through rear sprocket cluster as cadence drops • Hopefully stay in big chain ring up front • Near the end, get out of saddle and power over the top • Long steady climbs • Don’t power too hard at lower end – this could cause you to go anaerobic • Find comfortable cadence and settle in – maybe around 70 to 75 rpms • Use your gears! • Relax hands and upper body – no head/shoulder bobbing • Shift around on saddle – scoot back slightly • Stand only to regain momentum – not an efficient way to climb • Near top explode out of saddle and power over the crest
