After several development stages Craig Robertson and Chris Williams of Empire Cycles are ready to go into production with the AP1. The unique cast frame construction is designed and manufactured in the UK, and while it’s a popular manufacturing technique for motorcycles, this is the first time we’ve seen a cast downhill frame.
The suspension design is a high single pivot with an idler to help reduce pedal feedback. Swingarm spacing is 150mm, but the AP1 actually uses a lighter 135mm hub to allow space for the sliding disc mount, which is also mounted on the 12mm rear axle. An added bonus of this set-up is that the disc mount is always perfectly aligned with the hub and rotor. Chainstay length is adjustable between 426mm and 446mm and travel varies from 203mm to 216mm depending on the chosen chainstay length.
The AP1 frame will come as standard with a Marzocchi Roco WC shock with a Ti spring for £2,099. If you want the ultimate in shock technology you can have a Cane Creek Double Barrel upgrade for an additional £300.
The frame kit includes a rear shock, 1.5in reducer headset, seat collar and custom chain device. At present Empire Cycles will only offer the AP1 in one frame size with an anodized finish; colour options are still TBA. Contact:
