Exactly what I was looking for
I’ve been using Zwift with the Wahoo Kickr Core and it has completely transformed my indoor cycling experience. The trainer pairs seamlessly with Zwift, and the ride feels incredibly smooth and realistic, with responsive resistance changes that mimic climbs and sprints perfectly.
Setup was straightforward, and the Kickr Core runs quietly, which makes it ideal for home use. I especially like how immersive the Zwift routes feel – the combination of the platform’s visuals and the trainer’s accurate power readings really motivates me to push harder.
Overall, the Wahoo Kickr Core and Zwift are a fantastic combo for structured training, group rides, or just exploring virtual routes when outdoor riding isn’t an option. Highly recommend for anyone serious about improving their cycling fitness.
Great quality from a reputable company. I also have their knee sleeves.
Shipping was fast and efficient and reliable.
Would definitely purchase from the vendor again
James replied to my online inquiry promptly and in less than 24 hours my items had been sourced and the order dispatched. Very impressed with the professional and quality service. I highly recommend this business, in particular it's online service and sales platform.

I bought the fulcrum front wheel and the item was spot on. There was an issue with the bearing cap which was missing. I called the store and Conor, one of their technician resolve the issue without hassle.
Excellent customer service! I highly recommend.
Delivered quickly and good price. Campagnolo, always good.
I'm very happy with my Campagnolo Centaur 10 speed Powertorque Alloy Crankset. It was delivered very quickly in a sturdy box. It looks brand new ( it was manufactured in Italy in 2012 ). The crankset looks fantastic. All I need now is a bike to put it on. Thank you.
