SUMMARY:

STANDARD SERVICE PLAN - ANALOG BIKE & ELECTRIC BIKE

The Standard Bike Service Plan is perfect for any cyclist interested in keeping their bike in great riding condition. It's designed for bikes that get low to moderate usage.

Bring your bike in for adjustments as often as you need. We will fix those annoying rattles, adjust brakes so they have full stopping power, lube your chain and cables, and true your wheels if they get out of alignment. Got an electric bike? We'll keep it updated with the latest firmware.

PERFORMANCE SERVICE PLAN - ANALOG BIKE & ELECTRIC BIKE

Is keeping your bike in peak performance important to you? The Performance Service Plan is designed for bikes that get moderate to heavy usage. Do you mountain bike often? Do you commute by bike regularly? Are you a gravel grinder? If yes, this plan is for you.

The Performance Service Plan contains all the elements of the Standard Bike Service Plan, including drivetrain lubrication, wheel truing, brake adjustments, and Di2 firmware updates. It also includes specialty services like disc brake bleed, front suspension oil change, rear shock air can service, and tubeless sealant replacement.
