Shimano Gravel Groupsets
Here at MEC Bikes we are a proud dealer of Shimano who supply a wide variety of complete models and parts within their gravel selection.
Shimano is our most common brand that's used in our workshop for replacement parts/upgrades and is a popular option for our custom bike builds.
Please note that due to low stock we are currently unable to sell individual Shimano parts/components on their own as we are trying to accommodate stock for our mechanics to use in bike servicing and bike building.
If you are interested in a quote for a groupset, you can click ‘Make Enquiry’ above or please reach out to us and our team can help.
Below are the most common and recent Shimano gravel groupsets worldwide. Older versions of each groupset still exist on the market, so if you don't see what you are after please reach out to us and we will be happy to assist. Shimano GRX - The world's first dedicated components to adventure
