We aim to have all ‘Core’ model frame sizes available ex stock.

Eolus, named after the God of the winds, is the culmination of 5 years work developing and testing a new MTB platform. The design is based on the type of riding we do locally: singletrack trails in the woods, XC and bike packing rides across the South Downs and the occasional trip to more extreme terrain such as Wales or the Lake District.

The progressive frame geometry has a confidence inspiring 65-degree head angle and relatively long reach design, helping the rider to remain composed and in control when descending and tackling obstacles on the trails. The frame is packed with all the latest features including a super-tough 44mm head tube, internal dropper seatpost and 12x148mm boost rear axle spacing. The CNC chain stay yoke gives generous tyre clearance for at least 29 x 2.6”, with the possibility of going even wider depending on the tyre/rim combination. Our braced top tube/seat tube design offers improved stand over clearance to enable the rider shift their weight easily to maintain grip and balance. This feature also allows cables to be routed internally all the way from front to rear for an ultra-clean look.

The custom butted 3Al 2.5V titanium tube set is drawn from the same stock as our tried and tested road frames, benefitting from 16 years of titanium frame development. Tube shapes are optimised for stiffness, weight saving and compliance resulting in a durable frame that can be ridden all day long.
