At J C Cook we offer comprehensive range of cycle maintenance, servicing and repairs in our dedicated workshop. Whether it's a simple puncture repair or in depth maintenance our friendly staff will be happy to assist whatever your needs. On top of our regular servicing our specially trained technicians are able to carry out Shimano Di2 and Sram Etap software updates and fault diagnosis and also electric bike servicing and maintenance.
With every new bike sale we offer a free 5 to 6 week bike check up from date of purchase.

How to book a service

Simply drop the bike into us at any time and one of our trained staff will talk you through anything you require. If you require a quick turn-around it is best to call the workshop first on Grimsby 01472 210384 or Scunthorpe 01724 277718 to pre-book, this way we can pre-determine if any special parts are needed to complete the job.

How much will my service cost

Every bike that is received into the workshop will go through a pre-service inspection to outline the work required and the cost to carry out the work. Our specially trained workshop technicians will be able to talk you through everything that will be carried out and provide you with the quote for work.
All bike services are carried out on a case by case basis although some basic service costs can be seen below.

How long will my service take

During the pre-service inspection our staff will be able to give you a rough estimate for completion. This may depend upon specialist parts that may have to be ordered to complete the job. When the job is completed one of our friendly staff will call to let you know your bike is ready for collection. When you collect your bike one of our workshop staff will talk you through what work has been carried out a supply you with any advisory issues they may have found.
