Trying to decide weather to drop big coin on a light gravel rig for a race in August. The longest climb is about 21.7 miles at 4% and I weight 100kig with my current bike. It’s not light…I bet I could get 3kg…maybe 4kg…off of the weight.
OK so 4kg weight loss, 21.7 mile climb at 4%, let’s stay frontal area is the default 0.5m2 and air density is default 1.226 kg/m3. Let’s put rolling resistance at 0.01 (I’m guessing, it’s gravel of some type)
I’m figuring about 200 watts for this sucker.
Does this make sense so far? If so…are we really talking 1 minute slower for a ~2 1/2 hour climb? This doesn’t seem right but I’m having trouble making sense of this. Any comments you have would be most appreciated
