About Dirt Merchants
Dirt Merchants is independently owned by James Duncan and operated by a small but experienced team of local bike mechanics and enthusiasts. We offer top quality bicycle servicing, a wealth of knowledge that we are keen to share, and sell only the best brands that we believe in. We love to ride whenever we can and pride ourselves in having an expert knowledge of our products and knowing how to maintain and tune them so that you get exactly what you need and they achieve the highest possible performance. The satisfaction we get from assisting our customers to get their bikes fitted and tuned in just right is what makes us do what we do.
For customers who like to get hands on with servicing their own bikes we are the perfect solution for sourcing those specific replacement parts, as we can guarantee you are getting the right part. If we don’t have it in stock, we can usually have it in store overnight (on business days). Our mechanics are Shimano certified and with well over a decade’s experience working on all bikes, with specialist tools and a can-do attitude means that we often find solutions to tricky problems saving you costly replacement parts. At Dirt Merchants finding the best solution to make your bike ride like a dream is our focus.
Bio: James Duncan
Owner & Head Mechanic At the age of 10, James bought his first mountain bike from what was Bicycles Unlimited, in Courtenay Place in Wellington – it turned out to be a life-shaping purchase. He has never looked back. He has over a decade of experience in the cycling industry under his belt, Shimano certification and many hours of professional service centre training.

James also rode competitively for several years. His achievements include New Zealand under-23 XC champion, HT DH series champion and he also has a number of respectable Karapoti Classic efforts to his name. His passion for mountain biking has taken him around the world – he has lived in Whistler, Canada and has ridden trails throughout Europe and North America. In August 2010, James decided to pursue his dream of starting his own workshop-focussed bike store, and opened Dirt Merchants in Aro Valley.

  • Quality, honest and friendly service from three guys who know what they're doing, but don't act like know it alls. These guys always take the time to explain what repairs and required and why, plus the shop just has a great vibe and supports tons of local mountain biking events through donations and onsite.
