This product is the successful connection of steel and aluminium blocks that are presently produced. Block rails and support casings are made of zinc covered steel sheet. Supports and adjusting levers are made of aluminium. Having introduced such a "mixed" block to the market we wanted to come up to the expectation of our customers - you are getting the starting block only a little more expensive than steel ones but with the specially formed aluminium supports of the highest quality. The support is the most important block part; its tartan lining is shaped especially for better sticking to the ground. This solution protects lining against scratching by competitors' spikes.
