Acium, ("Ace i e um") might have started as a spelling error that stuck but once it became our business name it came to represent our passion as riders through our journey to curate products that align with our love for cycling upgrades. We want to bring you products that add value to your riding and be a business that raises the bar on what you expect. 

The Acium Standard 

We don’t list new brands until we’ve tried, tested it ourselves. We have high standards for our gear. Our commitment is bringing you the product and experience packaged, delivered and supported as if were our own new bike day. We know you’ve thought long & hard about it, and we want to overdeliver (Just looks at James' new TIME ADHX on our blog to see how much we love the gear we sell). 

Rider Curated & Supported 

Like you, we ride (or sometimes ride) because we enjoy the peripheral activities; post-coffee shop brew, club race banter, or retail therapy with new bike gear. When listing our brands, know that we’ve pondered, drooled and thought the same question you may have. As riders, ex pro and self-proclaimed weekend warriors, we have tested and experienced the products we list, making us poised to offer feedback or support based on your current or future cycling aspirations. We are not just an online bike store this is the part of the day where we try and repay our staff purchases off internally. 

Like you, we like to shop online and have been let down countless times after placing an order only be told that the product must be ordered from a supplier. We hate that. It can mean lost weekends of riding or ruined holidays because critical parts haven’t arrived, even if you ordered them with plenty of time. 

If a product is available for purchase online at Acium Sports, it is in stock and ready for dispatch from our local warehouse with no added waits to get your purchase to you. 

Use our stock availability counter on the 'add to cart' section of the product to find out how many of that product(s) we have left in our warehouse.
