Would thoroughly recommend - Michael answered my query very quickly, supplied feedback and I was able to order exactly what I wanted in a quick and efficient manner. Did I mention that the prices are also excellent? On the basis of my experience I have no hesitation whatsoever in giving a five start review.

Michael is fantastic and knowledgeable. Had my new bike fitted with new rims and tyres. He also installed the extras to the bike at a brilliant price. Highly recommended and great for local cyclists in the area!

Excellent service. Ordered Ultegra Di2 Groupset. Unfortunately my choice of chainset was out of stock. Michael gave me option of refund or send remaining items of groupset, and forward Chainset when available,date supplied. I chose the latter. Excellent communication and look forward to using again.

Great communication during the process of purchasing (and subsequently getting a refund on a product). The owner is responsive and the process couldn't have been smoother.

Super happy with the service. This is the second time Michael's serviced my bike and both times provided exceptional quality of work. I wouldn't take my bike anywhere else.
