Torque Analysis, Rotor Rings, rear-set cleats and an SRM

Finally spent some time tonight mucking around with my bike, my rings, my cleats etc.

 

I have been riding with the speedplay cleat adaptor for about two weeks in the most rear-set position (allowing a setback 25mm behind where I was before under the ball of the foot).

 

I have also been toying with the Rotor rings as well.

 

Here are two plots from tonight (average of 30s pedaling on an erg):

 

 

and

 

I will let you draw your own conclusions for now...

SaltAir 5-24

well, it was not my day in many ways...

 

1) the backwards cleat position has not helped my foot pain, but has dropped off some of the power.

 

a month ago I ripped a solid 15:35 on training wheels @ ~290w.

 

today I barely managed a 265w ave for the first run (and a measely 240w for the second.

 

2) I also ran two runs today and tried two sets of wheels.

 

 

oh, and jason, I hope you don't mind me throwing that up there (if so, drop me a line and I will rip it down).

 

these are just REALLY rough cuts on the data.  But it looks good as I started the season ~.345+/-

 

3) last but not least - dammit I have got to learn to check the kestrel for the auto off setting.

 

 

the highlighted portion is the start of run 1.

Kyle asked about something that I have been running for a few months...

 

hope this helps you Kyle...

Any takers?

Which of these is faster?  Which has a lower CdA?  Which has wider elbows?

 

 

no field test data yet, perhaps saturday.  I have my suspicions based on the work of some friends...

 

back profiles:

 

 

we shall see if the intuitive answer is the correct one.

 

Just goes to show, there are always gains to be had, even mid-season.

Another Saltair Windspeed Graph...

I ran like crap last night as my stomach disapproved of the effort.

 

But thought the 3 people reading this might want to see this (vs. the last one two weeks ago).

 

 

Clearly there is a trend developing in start times and windspeed.

 

More to follow as I hope to assemble a full database of data from this years saltair TTs...
