Grinds Lovely Anti-Nanging Device is still going very strong. Now in it�s third incarnation, the principal of protecting the spokes as well as the hub and using the immense strength of the spokes for structural support is well proven. The G.L.A.N.D.is actually made from proprietary plastic to keep the weight low and spread impacts evenly whilst grinding with as little resistance as possible. The G.L.A.N.D. MkIII is fixed to the spokes via cable ties or nylon webbing using the unique bobbles to keep the guard central and fixed. Super light, super low priced, will fit virtually any hub, with any lacing pattern, front or rear, without effecting spacing. Weight: 40g / 1.4oz (typical fitted weight) Price for 1 hub guard.
