Track Maintenance Schedules On Bike Components (Fork, Shock, etc.)
Certain components on bikes have specific maintenance schedules that are measured in miles or hours. For instance forks typically require maintenance every 20-30 hours of riding.
Since Strava keeps track of bikes and the rides they are used on, it could easily display maintenance warnings.
On the bikes page, you'd add 1 or more components (simple name is enough) with either a miles or an hours reminder.
After every ride is submitted, an easy notification can be given if a specific component passes the maintenance metric.
On the bikes page, you could reset the maintenance warning for a component to set it back to 0.
