# Cycling & Mountain Biking: sources and verification log

Checked 3 Oct 2026 (IST). Every fact on the page comes from the source listed here or is standard physics worked on the page. Fees, phone numbers and email addresses were deliberately **not reproduced**.

## 1. Physics (standard science, worked on the page)

| Item | Basis | Status |
|---|---|---|
| P = v(C<sub>rr</sub> m g cos θ + m g sin θ) + ½ρC<sub>d</sub>A v³; ρ = 1.2 kg/m³; no drivetrain loss or wind | mechanics; C<sub>d</sub>A 0.27/0.32/0.60 m² and C<sub>rr</sub> 0.005/0.012/0.025 **illustrative** | solved numerically in Python and in the lab JS (200 W, 85 kg, flat, hoods → 33.9 km/h, about 80% to drag) |
| Climbing: 8%, 85 kg, 200 W → 10.0 km/h, 92% to climbing, ≈ 796 m/h | same model | recomputed |
| Gear ratio × circumference (2.1 m road, 2.3 m 29-inch MTB) × cadence | geometry; circumferences approximate | recomputed |
| Stopping distance v·t + v²/(2a), 0.5 g, 1 s reaction; tip-over limit ≈ g × (horizontal CoM–front contact)/(CoM height) | mechanics; geometry **illustrative** | recomputed |
| Drop landing: v = √(2gh), average deceleration h/s (in g) | mechanics | recomputed |
| Drafting and slower-moving wake | general aerodynamics | qualitative only, no percentage claimed |

## 4. Not verified / left off

- **cyclingfederationofindia.org** now serves an unrelated gambling page. The page uses CFI's current site, cfiindia.in.
- **MTB Himalaya** (mtbhimalaya.com) now serves an unrelated betting site. **Not listed.**
- **Manali–Leh**: only Wikipedia and commercial tour sites were found, with no official source for route, altitudes or season. **Not listed.**
- **CFI event calendar 2026–27** is an embedded document we couldn't read, so no other national championship dates are given.
- **ABVIMAS**: no mountain-biking course with a stated duration was found. **Not listed.**
- **Super Randonneur** definition: the AIR page didn't load (404), so it isn't stated.
- **Fit India site** (fitindia.gov.in) didn't respond to our fetchers; the page links the PIB release instead.
