A bit about the 456 frame

We've been designing long forked hardtails specifically for technical UK riding for years. The 456 blends all our experience into an unshakeably surefooted, yet responsive steel frame with massive tyre clearance for all conditions use.

What's in the Finishing Kit?

A range of really nice components and upgrade options. You'll get:

Handlebars, Grips, Headset, Saddle, Seatpost, Seatclamp, Stem
