Specialized Sirrus X 4.0

The Specialized Sirrus X 4.0 mixes fitness hybrid speed with light-trail capability. Its 12-speed drivetrain needs more attention than the 9-speeds most hybrids carry.

Service Intervals
Chain (12s): check every 400 mi, replace at 1,500-2,000 mi Cassette: replace every 2 chains Tires (38c): replace at 2,000-3,000 mi Brake pads: replace at 1,500-2,500 mi Full tune-up: every 12 months or 2,000 mi

Narrow 12-speed chains wear faster than older drivetrains. Check wear monthly if you ride daily.

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.
