SKS are the Rolls-Royce of mudguards; they are virtually unbreakable & are very elegant. Their beauty is not just skin-deep. The stainless steel v-shaped stays make for easy fitting & the quick release Secu-clips are far safer than standard fixings, preventing front wheel lock up in case of a foreign object getting trapped between guard & wheel. The mudguards have no sharp edges & are amazingly flexible. The production process involves the encapsulation of fine aluminium foil within a matrix of high performance plastic. This process provides high resistance to corrosion & resulting in a high degree of flexibility. Mudguard set for front & rear: with traditional & unmistakable decorative stripes 3.4 mm stainless steel bolts & nuts from stainless steel front fork crown fitting, sliding bridge & fixed bridges of stainless steel including stainless steel assembly kit security fastening Secu clip (DIN 79100)
