I am a grinder at 6'2", 220# up long 4% to 8% grades. I hangout in the 34-23, 25, 28 combos on a 17# road bike and my cadence is in the 70's uphill.
This week my Kestrel RT-1000 is being modified with a long cage and 11-34 cassette. I want to be able to spin more in the 90 range and be able to conquer some of the epic rides in the Eastern Sierra this month. It will be a test to see if I have the cardiovascular fitness to spin more at altitudes of 5,000 to 10,000 ft.
