Hi chaps. wondering if there is a reason you recommend replacing the top bearing with a different type? (poly la la thingy)
I can see from the pics its a cracking alterative,
but I live close to a bearing shop and was wondering if there is a reason people arnt just putting in a like for like bearing ? (roller bearing I think it is)
The reason that people use the polyurethane bushes is that the original swivel bush is VERY expensive and tends to wear out quickly.
I would not try to use a roller bearing (or any bearing) as this will be worn before you get more than 50m down a rough lane/trail. Bearings are not designed to take that much load and will not last!
