Yes, this frame comes with ISCG05 tabs. If using a chain guide the rubber cable guide plug is not needed.

For customers ordering directly off our website, we are no longer accepting pre-orders due to uncertainty in global supply chains and production and with ETAs continually changing. However, we have added a "Notify me when this item is back in stock" feature for all our models. Just click the model, build kit, color and size you'd like then click on the notify me button and add your email. Once that bike arrives and is available for purchase you will receive an email notifcation.

If you are a customer who is looking to order a bike through your local Transition dealer or through the Transition Factory Outpost Store you will want to reach out to them directly.

Yes. This bike is designed to work with both air and coil shocks. We know there are a lot of great shock options outside of what we spec, but we have worked extremely hard to develop the tune in our supplied shocks. We believe they perform as good as anything else available in the aftermarket options.

Transition Bikes is not responsible for any damage to a frame caused by a shock that we do not spec. To verify shock fitment please email us at info@transitionbikes.com

Yes. Running 10mm more or less travel than stock is okay. Any more than 10mm in either direction can negatively affect the handling.

Yes, but this bike is built with SBG technology, which utilizes an offset in the range of 42-44mm. Running a fork with more or less offset would be taking away from the SBG technology package.

We offer three ways to demo a bike. If you find yourself in Bellingham, you can follow this link to schedule a demo through the Outpost. If you live somewhere else, you can follow this link to see what shops currently have demo bikes available. And finally, you can view our events page, located here to see which upcoming demo events we'll be participating in.

We don't offer any in-house financing. However, we do accept Paypal and you can apply for financing through them. Transition Bikes encourages you to use financing responsibly. We want you to get a new ride as much as you do, but we also want you to eat and live well.

Sizes MD-XXL will fit a standard sized water bottle. Size SM will fit a 15oz/450ml Fidlock water bottle
