They were lining up around the block for the last one, and the second Rouleur Classic promises an even bigger rush for the doors when it returns in the autumn.
The venue for this year's event is Victoria House in Bloomsbury Square and brands confirmed to exhibit include Colnago, Campagnolo, Castelli, ZIPP, Lightweight, Specialized, Cervelo and Scott.
But the Rouleur Classic is unique not for its stalls but for the guest speakers. This year the lineup includes Tour de France race director Christian Prudhomme, Jan Ullrich, former pro rider and founder of Storck and Sean Kelly, also a former pro rider and the almost unintelligible commentator on Eurosport.
Additionally, Sean Kelly has raided his attic and will bring along a wheelbarrow full of memorabilia including trophies, bikes, jerseys and medals. Just in case you wanted proof of his palmares.
Alongside the stalls and the speakers there is a cookery workshop from Team Sky and Dimension Data chefs, Henrik Orre and Hannah Grant.
The Rouleur Classic 2016 takes place between November 3-5 at Victoria House, London. Extremely limited Super Early Bird tickets start from £25 and are available to buy now from www.rouleurclassic.cc.
