Hammerhead Karoo 2


At some point, bike computers went the wrong way. They got small - too small - hard to read, hard to use, and more often than not, totally stressed you out when it came to creating or sharing a route. In other words, they took away from the experience of cycling.

The Hammerhead Karoo 2 bike computer is refreshingly different. It’s easy to use - really easy to use. It makes nice with routes. It can get you home at the rush of a button. It reroutes on the fly and shows you interesting POIs along the way. In other words, it adds to the cycling experience. And for those of us who don’t want to spend long minutes outside the cafe holding up the group ride or stuck in the middle of a field while we wait for our device to connect, the Hammerhead Karoo 2 is a revelation.

We’ll have a long ride review coming up soon, but for now, drop us a line if you have any questions. Or shop it right here and try it out right now. The road awaits.

Shipping & Returns

We ship the same day for everything other than entire bikes if you order before 11 am P.S.T. But if it's the weekend, we'll be out riding, and your order will leave Monday. Shipping costs are detailed on checkout, but we offer a few different services depending on your preference for speed. So if you need those new shoes for next week's ride or tomorrow's - we got you. And returns are easy, too. Send us a mail if something doesn't work out, and as long as it's unused and in its original packaging (naturally for apparel and footwear, you can try things on at home), we'll happily take it back within 30 days of your order.

If you have any questions or just want to say hi and talk about bikes, drop us a line.
