Computer, GPS & HRM Accessories Information

While head units for cycle computers, GPS and heart rate monitors are a sealed unit, there is a wide range of accessories, upgrades and replacement parts available for the fittings. Everything you need to fit a device is supplied with the original purchase but if you have several bikes and don’t want to have to keep switching the fitting attachments then fear not as these are available separately aftermarket. The good thing about the fittings is that practically all parts are available individually saving you buying a complete new system. From the humble wheel magnet, upgrading your GPS mount to a titanium one, adding an ancillary device such as cadence sensor or replacing the HRM chest strap, it’s all in here.
