hey guys, hows it going?
i have a different question on fixed gear conversions. at the moment i ride an old road bike, predominately in the gears 42x15 (73.6 inches) and 42x13 (84/.9 inches).
I did a Respiratory Exchange Ratio test at University and found that i was working my aerobic system with the 42x15, but not in the 42x13, which used muscular power. i had a test ride at a local bike shop of a fixed gear, and thought of changing my back wheel (needs replacing anyway) to a fixed. bike mechanic says it'll cost less for the fixed wheel, sprocket, and chain anyway; i can do the rest myself.
I've heard that its easier to run faster sprockets on fixed gears, as theres more mechanical power in the bike due to no deraillers and a straight chainline, and heard similar contradicting arguments.
from experience, would i be all right to train my heart on a 42x13 instead of a 42x15 if i converted to fixed gears?
my cranks are 170 and wheels are 700C if that makes any difference.
