Project description
Requesting an experienced bicycle mechanic to visit my personal commuter bicycle on-site for a full drivetrain tune-up and brake adjustment. The bike is used daily for a mixed asphalt-and-gravel commute of roughly 12 km each way, and the drivetrain has become noisy under load with occasional chain skip on the middle cassette cogs.
Scope of work: inspect and measure chain wear with a wear-indicator tool and replace the chain if elongation exceeds 0.75%; inspect cassette cogs and chainrings for «shark-fin» tooth wear and replace as a matched set if needed; clean and lubricate the full drivetrain (chain, derailleur pulleys, chainrings) with degreaser and a wet or dry lube appropriate for current weather; adjust the rear derailleur indexing (barrel adjuster, limit screws H/L) so shifting is crisp across all cogs without chain rub in the big-big or small-small combinations; adjust the front derailleur trim and limit screws if a double or triple chainset is fitted.
Brake work: for rim brakes — replace worn brake pads, true the pad toe-in angle, adjust cable tension and centre the caliper or dual-pivot arms so there is no rub against the rim; for disc brakes — check pad thickness, bleed hydraulic lines if lever feel is spongy, true rotors if they are warped, and adjust caliper alignment to remove rubbing noise. Check the cable and housing routing for both brakes and shifters, and replace frayed cable or cracked housing if present.
Logistics: the technician should bring a portable repair stand, a torque wrench, cable cutters, a chain tool, and common spare parts (chain, brake pads, cable and housing) so the job can be completed in a single on-site visit lasting roughly 60-90 minutes. Please propose a visit window within the stated timeline and confirm whether a deposit for parts is required in advance. Photos of the current drivetrain and brake wear can be provided on request before the visit.
