Cycle Technique is a great shop catering both to pure cyclists and to the triathlon crowd. Their friendly and knowledgeable staff will be able to give you great advice for all you cycling, running and swimming needs.
In addition to all the great stuff you can buy at the shop they are the only store in town that also has a full blown training centre, which includes a spin room and endless pool. Whether you've worked up your appetite as a result of a big workout in the spin room or a shopping spree, there is also a cafe right in the shop where you can grab a sandwich and a cappuccino before hitting the road.
The guys at CT have always gone the extra mile for me, getting my bike ready on short notice when their in peak season and even lending me a bike to race on when they found a crack in my frame.
