Shimano GRX, with its gravel specific ergonomics, optimized gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world. It isn’t a reworked set of road components made for all-terrain riding, this groupset represents a ground up look at how cyclists want to explore their world. Shimano GRX helps you eliminate excuses, instead urging you to try that rough sidetrack or ride that little bit longer. It offers you the option to Explore Beyond.

All UK deliveries are sent by express courier, usually on a next working day delivery. In stock parts, accessories and clothing orders placed before 1pm we’ll aim to dispatch the same day. All deliveries of bikes are made to order, so please allow up to 3 working days for build time before dispatch.

Built Bikes

Built bikes are shipped in large box, 95% assembled. When you receive
the box all you’ll need to do is insert the wheels, attach your pedals
and set your saddle height. If you’ve provided your bike fit data to us
we will have marked your saddle height on the seat post for you. Torque
settings, manuals and first steps videos are all available in our Vielo
owners area. All deliveries will be dispatched with tracking numbers
emailed to you.

Bikes are sent via Next Working day Courier. Some deliveries in areas
such as the highlands or islands will require additional time for
deliveries. 99.9% of our deliveries arrive on time, however sometimes
delays in transit happen. If your order is time critical please let us
know in advance and we’ll do all we can.
