This aero bike sports some features that likely won't be allowed in competition.

Don't miss a moment from Paris-Roubaix and Unbound Gravel, to the Giro d’Italia, Tour de France, Vuelta a España, and everything in between when you join Outside+.

Stefan — Stefan Küng chose BMC’s brand new Timemachine Road Disc for his training ride in the days leading up to the 2018 Tour de France. It’s BMC’s newest aero bike. Photo: Dan Cavallari | VeloNews.com

Stefan — The Timemachine road features some triathlon touches, like the integrated bottle cages. Photo: Dan Cavallari | VeloNews.com

Stefan — This integrated structure will likely have to be removed before it can be used in competition, since it probably constitutes a fairing. Photo: Dan Cavallari | VeloNews.com

Stefan — The down tube features some unique shaping, presumably for aero benefits. Photo: Dan Cavallari | VeloNews.com

Stefan — That down tube shaping seems to work in conjunction with the integrated water bottle cage system. Photo: Dan Cavallari | VeloNews.com

Stefan — Unlike the shallow D-shaped seatpost on BMC’s Teammachine, the Timemachine Road features a deeper D-shaped post. Photo: Dan Cavallari | VeloNews.com

Stefan — The seatpost’s shape likely adds some aero gains, but it can also make for a harsher ride. Photo: Dan Cavallari | VeloNews.com

Stefan — The stem is quite long. This allows for an aggressive, forward position that sprinters trend toward. Photo: Dan Cavallari | VeloNews.com

Stefan — Like the Teammachine, the Timemachine features an integrated stem that allows the mechanics to route cables and hoses out of sight, down through the head tube. Photo: Dan Cavallari | VeloNews.com

Stefan — The stem features a thin profile, but it’s fairly wide across. Photo: Dan Cavallari | VeloNews.com

Stefan — Aero bikes often appear smoothly sculpted, but the Timemachine takes an opposite tack: there are clear lines and angles visible around the head tube. Photo: Dan Cavallari | VeloNews.com

Stefan — The fork features an integrated brake fairing. Photo: Dan Cavallari | VeloNews.com

Stefan — That fairing certainly adds aero benefit, but like the water bottle cage system, this feature would likely need to be removed before use in competition. Photo: Dan Cavallari | VeloNews.com

Stefan — The fairing helps shield the brake caliper from the wind, since the caliper’s somewhat blocky shape adds drag to the front of the bike. Photo: Dan Cavallari | VeloNews.com

Stefan — Clearance is tight. Photo: Dan Cavallari | VeloNews.com
