We view all our riders as individuals and as such all our stock geometries are unisex in design – offering 11 finely tuned stock sizes from 50cm to 60cm, with the additional option of a full custom design and build (+£300).


Because every Endeavour frame is made to order here in our Sussex workshop, we have complete control from start to finish. This allows us to control every step of production, and allows you to fine tune your Endeavour your way. From custom geometry through to bespoke finishes and more. So if a stock geometry frame doesn’t work for you, we’ll make you one that does, and with careful consideration on components we can further customise every build to ensure the fit is perfect.


We feel that having a frame that fits you perfectly is a critical part of the process. We have over 20 years of bike fitting experience and data to call upon to ensure your riding position is absolute pinpoint. You can make an appointment here for a fitting. No obligation.


Alternatively you can send us any fit data you have or if you have a bike that fits you perfectly, let us know and we can go from there.


Further information on our sizing and frame geometry can be found here.

Opting for an individually crafted frame presents the benefit of total customisation, tailored specifically to match your distinctive style and riding preferences. This flexibility enables the meticulous adjustment of each frame to cater to riders' specific needs, encompassing personalised frame geometry, customised cable routing, the addition of extra eyelets, and the option for unique frame finishes, including bespoke paint designs. Virtually anything is within the realm of possibility.


When considering complete bike purchases, the range of achievable specifications is extensive. If you have a specific vision for your upcoming bike build, just let us know, and we can turn your ideas into reality.

Endeavour

Steel bikes have been present in the Enigma range for over 12 years, and although we are more widely known for our titanium frames, the roots of frame building lie in the tradition and skills honed over generations of steel frame builders. In a world of carbon and aluminium bikes there is something ‘Enigmatic’ about a modern steel bike, that provides a beautiful ride quality and modern performance blended with classic, timeless styling.

The Endeavour is handcrafted from a carefully considered blend of Columbus and Reynolds tubing with geometry optimised for stability over challenging terrain. Generous tyre clearance for 700c x 43mm or 650b x 47mm tyres ensures a wide range of wheel/tyre options for real versatility. There are mounts for mudguards, a pannier rack, and fork mounted cargo cages along with a versatile cable routing system to keep things tidy whether you’re using 1x, 2x, mechanical, Di2 or Wireless groupsets. Aimed at off road and endurance riding, the Endeavour frame features a higher stack height than some of our other models to enhance comfort levels over long distances.

The Endeavour is a striking, versatile, modern gravel bike for lovers of steel machines and sports a beautiful ‘Fade’ colour scheme for a stylish, contemporary look.

A feast for the eyes. Enigma dealer LightWolf Studio from Dresden, captured this stunning Steel Endeavour build assembled by their mechanic Nills.
