Have you found what you are looking for?

Is this mount compatible with the Hammerhead Karoo 1 or 2? It will fit, but requires an adaptor. These computers are heavy (especially the Karoo 1) and when used with their adaptor, sits in a raised position. This allows it to rock during use, increasing the likelihood of failure. Our mounts are not designed with either Karoo in mind and we will not stand over any that break while being used with a Karoo computer. If you still wish to go ahead and use a Karoo with one of our mounts we strongly recommend the use of a safety tether.

Carl Blake
Best upgrade for Cannondale SystemBar

The stock computer mount on the SystemBar was always disappointing for me as it was too high and the plastic puck often wore out due to the single central screw design. The JRC mount is brilliant as it solves both issues. Excellent quality materials and fast delivery.


Great quality, rock solid compared to plastic alternatives!

Quality computer mount

Absolutely top

Mark Verrall
Great company

Very high quality components and the service level is above and beyond so many other companies. When my mount was lost in the post Josh the founder personally took the time to call me and made sure the replacement got to me within a couple of days. Great items and a great company .
