Headset spacers aren’t on the top of most folks’ lists as a way of saving weight but these splined alloy spacers from Ison are as light as ones made from carbon and cheaper too. Not that headset spacers are collectively a cheap product — 70p for a 2mm ring of alloy is still pretty expensive. When we queried the original price (£1) Ison did decide to drop it, bringing the spacers in line with the competition. It’s only a small saving but it’s still worth it if you have to buy a handful of them.
