you can get monty brake pads for smooth rims as that is what i use they are brill, i use mine with a bit of tar work ausome. if you send me your brake including a £3.50 and a S.A.E with the right size to fit the brake in and i will bleed the brake with proper magura mineral oil. the cost is to cover the cost of the oil an time. i have never been a great fan of grinds as they wear your pads down faster and weakens your rim i currently run a magura on the front and this is just right. i am now going to disk as a matter of preference. Here's the link for the brake pads LINKY
