I test rode an Enigma Ego Steel at the weekend, absolutely amazing, very light and responsive. I also test rode the Ti version which to be honest wasn’t as much fun. I went to the Enigma open day on saturday, great bunch of guys, met the frame builder, actually held the raw steel and Ti tubes they use, the weight of the steel was incredibly light.
Benji from ST also gave the St Ego raves reviews, I’ll be ordering mine soon I hope.
