First step, look at your cranks to get an idea of the type you have. We support the most popular fitments which covers 99% of the market. There are lots of very niche ones and old standards, unfortunately we cant do everything.

Second step, check the offset you need, please dont ask as googling it for you is pretty inaccurate.

Third choose the size and colour to suit your style!

All our rings are 100% manufactured in the UK from high quality 7075 T651 aerospace grade aluminium. Its alot more expensive than 6082/6061 but its hardness means it lasts much longer. Watch out lots of the Ali-express specials out there are 6061 with 7075 lasered on them, we have tested them with a Niton gun (X-ray Spectragraph) and yet to find one which is actually made of the good stuff!
