Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

2026 Forbidden Heathen Ti Frameset

Season:2026

Brand:Forbidden

Code:000.102.000

A slack aggressive hardtail MTB featuring our ONERIDE proportional sizing designed around a 130mm fork. A bike to be cherished or to be neglected. Build it up to beat it down year-round or bless it up with bespoke bits ‘til your friends start asking what you really do for work.

Smaller sizes (S1 & S2) run an MX wheel setup, while S3 & S4 are full 29. This size split allows us to maintain our front-centre to rear-centre ratio and preserve the intended ride characteristics across sizes.

The slack head angle might raise eyebrows for a short-travel bike, but it’s deliberate. A shorter fork keeps the geometry consistent under compression. Meaning the Heathen remains composed when it matters most. This trail-ready chassis is intended to be a comfortable companion on everything from spicy XC loops to loaded up haul through the backcountry. A metallic mentor ready to guide us back to a life of mechanical minimalism.

● S1 & S2: MX | S3 & S4: Full 29
