The finest addition you could ever make to your machine, the Hyperpro Combination Kit ("combi kit") comes as a complete package that includes the Hyperpro rising rate front springs, matching Hyperpro rising rate rear spring, as well as matching fork oil and a thorough manual that tells you how to set your bike up for a perfect ride. Softer initial travel, smoother action through the stroke, and greater resistance to bottoming mean that you will finally have the suspension setup you have always dreamed of, but did not know how to get. Best of all, the kits for most machines are barely more then the cost of a good tire, so you can now have vast improvement to the ride and control of the machine without the huge expense of major suspension replacement or re-working. We even offer a 15 day return policy (please call US sales for details), that is how confident we are that you will join the ranks of those in the know!
