No replies here Dudds wosson ? The bearings are what as known as the sealed type so in theory at least they should require no maintenance,but,theres always one of those-now and again i just put a drop of oil on one side and spin the wheel as sure as eggs a little will get in there.I use auto transmission fluid as this is nice and thin and also has loads of detergent and will dissolve the dirt in there also,had mine now for 2 seasons and a bit and still nice and smooth-(theyll probably go to being a little rough now !!
)-coming down our way again next year ?,cheers PC.
