Climb & Sector Profiling: Variable Gradients, Micro-Sectors & W' Anaerobic Battery Protection
The Trap of 'Average Gradient'
Have you ever looked at a route profile that described a climb as 'a gentle 6% average grade', only to find yourself grinding up a brutal 15% switchback that almost stopped you in your tracks? That is the trap of average gradient: a climb's average number often hides steep, punchy ramps that drain your legs.
ChainLink solves this by breaking climbs down into 100-meter micro-sectors, showing you the exact steep pitches ahead so you can pace yourself and shift gears before your legs burn out.
Your Anaerobic Battery: Managing Your High-Intensity Reserve
Think of your cycling fitness as having two power sources:
- Your Sustainable Engine (FTP / Threshold): The steady pace you can maintain for a long time without your legs burning.
- Your Anaerobic Battery (W'): A small, rechargeable battery of intense sprint energy. Every time you punch over your threshold to get up a steep 14% kicker, you draw power from this battery.
If you surge too hard and drain your battery to 0%, your legs lock up and you are forced to slow down immediately. ChainLink models your battery in real time, showing you how much reserve you have left and how quickly it recharges when the gradient flattens out.
Smart Pacing & Gearing Tips
To help you ride climbs faster and feel fresher at the top, ChainLink provides two simple pacing safeguards:
- Surge Capping: Reminds you to keep steep-pitch surges short (under 45 seconds) so you don't drain your battery too early on a climb.
- Gearing Advice: When a route features sustained pitches over 11%, ChainLink suggests mechanical gear options (like a 32T or 34T cassette cog) so you can keep a smooth 85+ RPM cadence and save your knees.
