Just in: Enigma Ezona ST, steel road bike with Shimano 105

Enigma's brand new £799 steel frameset comes in for testing

Winter is the ideal time of year to be riding a reliable and comfortable steel road bike equipped with mudguards, and that is exactly what the brand new Ezona ST from Enigma Bicycle Works is. It’s their latest steel frame and costs £799, with the complete Shimano 105 build we’ve got in for review coming in at £1,549.

Based down in Sussex, Enigma has carved itself a reputation for beautifully made titanium road bikes in the past decade or so that it has been in operation. It also offers steel for those that don’t have the budget to stretch to titanium, or simply prefer the ride of a good steel frame.

The new Ezona ST aims to make owning a steel frame a little more affordable. It uses a Columbus Zona double butted tubeset throughout. The frame is handmade in the UK, and there is no doubting the quality of workmanship on show here; it’s exquisitely well made.

Enigma uses the same geometry as the long-running Etape titanium touring bike, designed for those who like to ride fast but favour a bit of comfort. It’s slightly higher at the front but not as much as many of the modern sportive bikes with huge head tubes.

The frame will accommodate 25mm tyres with mudguards fitted. It’ll go wider if you remove the mudguards but we reckon most people interested in this frame will be wanting to use mudguards for winter and year-round protection. All cables are externally routed, the headset is integrated and the seat tube accepts a 27.2mm seatpost.

Frame weight is a claimed 1,650g for a 56cm, with the complete bike pictured here weighing in at 10.3kg (22.49lb). The frame is available in a choice of three colours; Jaguar Red, VW Ice Metallic or Fiat 500 Blue.

Just one build is available for the new Ezona ST, and that features a Shimano 105 groupset with Enigma’s own Etape carbon fibre fork. Enigma also supplies its own aluminium handlebar and stem. Mavic’s Aksium wheels are solid and reliable, and fitted with Continental Ultra Gatorskin 25mm tyres. A Selle Italia saddle sits atop an aluminium Deda seatpost.

Enigma doesn’t offer a bespoke option for this new frame, but it is offered in six sizes from 52 to 60cm. Measurements for our 56cm test bike include a 577mm stack and 383mm reach, a 560mm top tube and 175mm head tube with 425mm chainstays.
