There is a guy (JoB, I think) who has a couple – a steel elite and another, I assume a steel, single speed CX. The CX is on Enigma's site in the users bike's section. Not seen him post on here for a while though
A guy at work also has a steel elite with couplings. He speaks very highly of it he also has a Colnago C50 and a Van Nicholas so know a bit or two about bikes. Only complaint he had was that their lead times for custom are little on the long side – but that may not be an issue for a stock Ti geometry.
I don't have an Enigma but have two Omega's (Ti Alchemy and a carbon one) from what was then Mark Reily's own company. Two friends also have Omega Radix's I think which is in effect what evolved into the Echo. All of us are very happy with them – although to be fair for my friends these are their only serious road bikes.
I am looking for an excuse to buy one – but thinking more along the lines of a steel one. I am at that age 😆
