    ‘Bike Check’

    • Bicycle evaluation fee, applied toward repair cost if you’d like to move forward with the bike repair. $30


    • Brake adjustment, pad alignment and cable adjustment (per wheel). $15
    • Brake pad installation, includes pad alignment (per wheel). $20
    • Disc brake rotor truing, per rotor. $10
    • Hydraulic brake bleed service (per wheel), piston cleaning and re-setting; available for Hayes, Magura, Shimano, Tektro, TRP brakes, $45 per wheel.

    DOT-fluid brake bleed service, which is common with SRAM’s hydraulic brake systems, $100 for the first wheel ($50 for the second wheel).  Full disclosure regarding DOT brake-bleed service, we’re happy to bleed these brakes, but this is not well-suited for our mobile operation, particularly with regard to not-Earth-friendly DOT-fluid and the need for a well-ventilated area; a pick-up and drop-off may be required. Another note on DOT hydraulic fluid, it’s hygroscopic, which means it absorbs water when in the presence of water (e.g., humidity). And water will eventually find its way into your hydraulic brake set-up through micro-pores throughout the ‘closed’ system’s lines and seals. Why’s that bad? Water lowers the boiling point of the DOT fluid, which degrades braking performance, which is one of the reasons regular hydraulic bleeding service is recommended. Also, for the same hygroscopic reason, once a DOT fluid container is opened, it cannot be stored as water/humidity will find its way into an unsealed DOT container, which will quickly render that fluid to a not-well status. Hence, a new bottle of DOT fluid is needed for each DOT bleed service. On a related note, Mineral Oil, the friendlier hydraulic brake alternative, has a slightly lower boiling point than (non-water-contaminated) DOT fluid, which some will point to as an advantage of DOT fluid. Mineral Oil is also often more expensive than DOT fluid, another flag-waving point for DOT-fluid enthusiasts.
