So I’ve finished my rough draft of wheel selector, it’s live here:
Mainly the biggest hurdle I’m having is coding the damn thing into a website.
So right now what it is essentially a power estimator given there’s zero cross wind, no rolling resistance, and you’re riding by yourself (aka Ironman). It’s estimating pretty high on the power/work numbers based on my own rides.
What it needs to be a viable wheel selector:
- Wind included (with inclusion of atmospheric boundary layer effects)
- Wheel drag across range of wind angles (currently only running for 0 degrees, which means all wheels are pretty much the same)
- Add rolling resistance
- Time spent Drafting?
- TT position
- Refined bicycle rider CdA (this is pretty rough currently, the topic of it’s own blog post)
- Add more explanation to what the hell is going on
Other things I plan on doing
- Some sort of submit to database, involving entering your ride metrics (from power meter). This could help refine CdA measurments, which are particularly difficult to estimate
- Better interface (ajax implementation, oh the confusing computer languages, why cant everything be like matlab…easy)
- Step 2: ?????????
- Step 3: Profit!
Ultimately I’d like to incorporate something like this into what this guy did here.
But that’s a LONG way off for a side project.
I don’t want a silly plain power estimator, that doesn’t really give you much (plus that’s kinda the reverse solving process from what you need to benefit you as a racing cyclist). With this tool, you could essentially calculate your power needed for say a mountain cilmb, pick which wheelset is best, etc.
