Workshop

Keep your bike running smoothly through winter with a service.

Forks take a beating in the winter months with mud and grit all over your stanchions. If you didn't service your suspension after summer, don't let it get too grimy!

Also consider your tyres. Some Specialized bikes come with the Slaughter in the rear, which is a super fast summer tyre, but not all that great in the wet. A Ground Control or even a Butcher is a great rear winter tyre. We can also top up your sealant.
