Dirt Merchants is a mobile servicing workshop equipped to deal with all your mountain bike servicing needs. James Duncan, Dirt Merchants’ owner and operator, has a wealth of knowledge and experience and is now handily operating from a mobile servicing van (aka Vanzilla). James is able to come to you for on the spot servicing, or pick your steed up for a more detailed service.
James is still equipped with all his usual quality parts and is ahead of the game with set-up and servicing requirements and the latest products. He has a policy of test riding and double checking all bikes for performance and safety before you ride away.
The list below outlines Dirt Merchants service packages from basic tune-ups to complete overhauls. You can easily make a booking on our contact page, telling him when you would like your bike to be serviced and what sort of service it requires. Pick up days are Mondays and drop back days are Fridays each week. James will endevour to have your bike for no longer than the week if he cant service it onsite.
Its worth noting that for a call outs there will be a minimum $100 charge which can be comprised of both labour and any parts used. This covers up to the first hour of servicing for your call out.
The Basic Service is a great option for a pre-race check and tune or if you are on a budget and are simply looking to keep your bike running smoothly. Parts additional. Includes pick up and delivery or on site van service.
The General Service is our most popular service, ideal for any bike that has completed its share of missions and now needs a revival. Parts additional. Includes pick up and delivery or on site van service.
The Deluxe Service is a thorough overhaul, great for hard working commuter, mountain and road bikes. Bikes are often exposed to a lot of muddy, gritty conditions in New Zealand so bottom brackets, seat posts, hubs and headset fastenings need to be removed, serviced and refitted periodically to avoid components becoming seized. We highly recommended this as an annual service or in preparation for the coming race season. This is a full inspection of your bike and covers the labour component of replacing all worn or damaged parts other than frame pivot bearings required to bring your bike back up to tip top condition. It also includes the labour for a rear shock air can service. Parts additional. Includes pick up and delivery or on site van service.

Recommended at 50 hours. Removal of forks lower legs, all oil in open bath dampers, air spring chamber and lube oil drained. Castings cleaned and reassembled with new oil and dust wiper seals. This is a great service to protect your fork from expensive upper tube “stanchion” damage that can occur when dust seals fail letting fork leg lubrication run dry and dirty. We recommended this service be conducted between full fork service intervals.Key aspects of this service:
Recommended at 100hours. A full suspension fork service should be conducted at least every 12 months on forks that get regular use throughout the year. Over time contaminants build up inside forks that eventually impede performance and accelerate wear on internal parts and seals. Your fork will be completely disassembled during the overhaul so that parts can be cleaned, repaired or replaced.
Removal of the forks lower legs, all oil in open bath dampers and damper cartridges drained, air spring chamber and lube oil drained. Castings and internal components disassembled as required to clean, inspect and replace all seals.
Key aspects of this service:
Recommended at 30 – 50 hours. It is generally recommended that your air sleeve be serviced more frequently at 30 hours of riding in wet and muddy conditions, to maintain optimal performance and avoid shock body damage.
Key aspects of this service:
Dropper posts are subject to eccentric loads by nature and are often exposed to mud buildup from the rear tyre. As grit builds up and grease no longer lubricates moving parts well enough, bushings and seals begin to wear and over time dropper posts sag, stick down and develop excess fore and aft play. For Rockshox Reverb posts this is an extensive service where we completely dismantle all parts, clean and inspect, replace o-rings, bushings and dust wiper seals as well as bleed the post’s damping circuits and hydraulic remote. For KS dropper posts having sealed cartridge units and cable remotes it is a simpler procedure where we dismantle, clean and inspect, and replace bushings and dust wiper seals as required.
Key aspects of this service:
Shimano Brakes $30 each. Other brands $40 each. As a result of wear or damage to the braking system, hydraulic braking fluid can become contaminated with air and sediment that will often cause brakes to fade under hard braking and generally feel spongy at the lever. Brake fluid also degrades as it ages and regular flushing of the fluid is recommended. Provided there is no lasting damage to the braking system a brake bleed will have them feeling as good as new. Pressure test inspection for sealing issues (trouble shooting).
Note: Any repairs that are required before the bleed if done may not be included in the labour charge
