After a very successful first year introduction, we will be fully moving over to our own branded Glass filled nylon wheels in a few weeks. The metal wheels will be discontinued, and we will be reducing the cost of all kits affected, (only about 1/4 of our range). Power bogies will carry the metal wheels until our stocks have run out. For customers still wanting metal wheels, metal treaded wheels can be purchased directly from Slaters. These wheels will be a direct replacement on our Swift Sixteen axles.
