5 / 5 stars
All Terrain Cycles

Bought this for my Madone 4.7. Very easy to install and also to set up. I am using this with a Garmin Edge 500 and despite the fact that they are not from the same manufacturer the Ant+ system allows the units to work well together. I've been riding with this unit for approx 8 weeks now and have had no issues at all. The service from All Terrain Cycles was first class, the product was well protected by the packaging and delivered in a couple of days. I highly recommend All Terrain Cycles and this product
