Trek Marlin 7

The Trek Marlin 7 is one of the best-selling entry mountain bikes in the world. Most Marlins are under-serviced, and most of their problems trace back to that.

Service Intervals
Chain: check every 300 mi, replace at 1,200-1,800 mi Cassette: replace every 2-3 chains Fork service: annually Brake pads: replace at 800-1,500 mi Tires: replace when knobs round off, typically 1,500-2,500 mi Full tune-up: every 12 months, first service at 300 mi

New Marlins need a first service around 300 miles: cables stretch and spokes settle.

Track it automatically

Saddle connects to Garmin, Wahoo, and Strava, counts every mile on your bike, and tells you when each component is actually due. Then it books the work at your local shop in one tap.
