Your New Bike

Thank you!

First, thanks for purchasing your new bike from us. We really appreciate it. You should already be set up and ready to ride. Secondly, we'd like to take a second to give you some more help and info on your new bike.

Record Your Serial Number

If your bike gets stolen, you'll need the serial number. Even if you find it for sale online and 100% know it's yours, the police will require a serial number. The serial number for pretty much all bikes is stamped somewhere on the bottom of the bottom bracket (where the cranks are). Take a photo of that and write it down.

Specialized bikes have a "Peel Me" sticker that includes the serial number. This is found on the bottom of the down tube. Take that off and stick it somewhere safe with your receipt.

We generally record your serial number at the time of purchase, but ultimately, it's your responsibility to record the serial number.

Regular Service

Like anything mechanical, bikes need some love here and there. Let's take a moment to explain what a new bike will generally need in your first year of riding.

Free 6 Week Check

We offer a free 6 week check on all new bikes to guarantee that everything is still running well. Sometimes gear cables can settle in and start to make a little bit of drivetrain noise. This check is basically the last step in a bike's quality control. Contact us and we'll get you booked in.

 Comp Service

If you ride regularly (commuting or 1-2+ MTB rides a week), you really should be in every 6 months or so. As chains wear and "stretch" in length they start to wear everything else they touch. If you stay on top of your drivetrain, it lasts longer and rides better. A Comp Service is from $80 (labour only).

Annual Service

These are add-on services for full-suspension bikes and bikes with dropper posts. Both of these should be done once a year and are easily added on top of a Comp, Expert or Pro Service.

Fork and Shock Service

All full-suspension bikes and hardtail bikes with an air-sprung fork ($1300+ bikes, usually) need regular suspension service. We recommend an annual fork and shock service to keep your fork and shock buttery smooth. Dust and dirt eventually work their way past the seals and into the oil, degrading the forks performance. New seals, oil and a thorough cleaning will restore the fork/shock to like new. You'd be surprised how much better they'll feel afterwards. Like night and day.

Dropper Post Service

Just like shocks, dropper posts need service to keep them smooth and trouble-free. The Specialized Command Post should be serviced once a year, sometimes more if ridden heaps or in harsher conditions. If your post is having trouble extending or just not as smooth as it once was, it probably needs a service. This service is only $90, which includes both labour and parts.

Want to Learn More About Your Suspension?

We have this clever little device called the ShockWiz that takes the confusion out of setting up your bike's suspension. It analyzes a fork/shock's performance and makes straight-forward recommendations on what you can change based on your riding style.

Good for all experience levels and riding styles. Even if you have a pretty good handle on how a shock works, you might still gain some insight and have fun tinkering with it anyways.

They're expensive on their own, but we hire them out for just $60 per weekendLearn more.
