Spent last weekend on the hills again, but was spoilt by Samco hoses being force off halfway up hill on both Sat and Sun.I am using Mikalor clamps of correct size, but the samco is pulled from under clamp leaving this on alloy. I use 1.7 bar on practice runs and switch to 1.9 bar on final runs. Anyone with good ideas. I have read steve,s idea, but somehow doubt wether this will stop the clamp from being slid off end of samco. I am thinking of trying to weld dimples under clamp to penitrate into hose. cheers den.
