We can talk forever about cycling. Sorting out tricky problems, dreaming up adventures or swapping stories of epic trips are welcome diversions. And we're keen as mustard for your ideas about how to improve Ground Effect products to better meet your needs. So write, call, beat drums or send smoke signals to us.

We hold no stock or samples at our office in Ferrymead. However, if you hang your hat in Christchurch or are passing through you're welcome to drop in on us, place an order or arrange an exchange. Orders are despatched directly from our factory and delivered to you by courier the very next day. 

We're generally around Monday to Friday, 9 to 5 (NZ time). Weekends are for biking so you'd be dead lucky to find anyone here then.
