This is the biggest ever discount on the prettiest-ever performance bikenav. Hammerhead is now owned by SRAM and has a rosy future. Karoo 2 is already renowned for its ease of use, fantastic screen and a plethora of metrics, charts and navigation. What’s not to like? A: Nothing.
Karoo 2 normally retails at US$399 / £359 – knock of a third in today’s sale
Also, buy in the USA at PowerMeterCity – uses code THE5KRUNNER10 for 10% off, it MIGHT work over and above the sale price but works normally if you miss the sale
