Just a couple of weeks ago BMC unveiled the angular new Timemachine Road Disc that took inspirations from the tri bike to integrate aero storage. Now that original Timemachine which debuted back at Kona in 2016, finally gets its own update with disc brakes. The core of the Timemachine 01 Disc’s aero shaping and integration remains mostly unchanged, but the move to disc brakes does free up BMC designers for clean caliper integration.
2019 BMC Timemachine Disc integrated triathlon/TT bike
Called by BMC their ultimate triathlon machine for its improved aerodynamics, the new Timemachine 01 Disc promises the best in handling and control for technically demanding triathlon and time trial courses. Developed to be a multi-sport bike the Timemachine Disc honed in on “a rider-focused fit, cockpit versatility and aerodynamic disc brake integration.” Doing so a number of aero storage and fair solutions are included, all of which seem removable to meet the demands of a race official.
Aerodynamic Tech Details
With regards to aerodynamics, BMC works with what they call a revised SubA concept based on minimizing exposure to the wind. The new bike works with 3:1 truncated aero tube profiles & shaping developed to be stable in crosswinds, an external straight 1.125″ steerer/hinge-fork design, maximal component integration from front to back, and integrated disc brake caliper covers.
Of course disc brakes just move the calipers away from the outside of the spinning wheel, and they introduce rotors. But discs also allowed BMC to more cleanly integrate brake routing, and the calipers themselves get totally shrouded by clean fairings – taken to an extreme even more so than found on the Timemachine Road Disc.
Those integrated aerodynamic caliper covers optimize airflow around the flat mount disc brake calipers ahead of the 12mm thru-axles, while keeping airflow across the rotors to maintain full heat dissipation performance.
BMC carries over their adjustable Position-to-Perform (P2P) system that adapts to high or low fits on the bike. So whether you are a time trialist or triathlete, you’ll be able to set the Timemachine Disc up for style of racing while still getting the most out of the bike’s aerodynamics.
Beyond the base stem+bar height setup itself, the overall unique V-Cockpit offers plenty of stack height adjustability, and claims comfortable vertical compliance without a loss in handling precision.
The more conventional Flat-Cockpit setup still delivers to most in aero efficiency, allowing for the lowest extension stack configurations. The Flat-Cockpit basebar can even be mounted upside down to get riders even lower
For integrated storage like we saw on the Timemachine Road Disc, this race against the clock Timemachine features removable rear-mount equipment storage box, top-tube fuel box mounts, and downtube dual-mount bottle cage options.
But drop those boxes, run the Flat-Cockpit, and the adjustable seatpost in its rear-most position (actually mounted behind the normal seat cluster), and the Timemachine Disc becomes UCI compliant for your next pro time trial.
Geometry, Spec & Availability
The new Timemachine 01 Disc is available only as a framekit for you to build up as your ultimate tri or TT bike with up to 27mm tire clearance. For 5500€, it includes the 1300g frame, 425g fork, V-cockpit basebar + Profile carbon extensions, and the seatpost (Flat-cockpit bar available separately).
The Timemachine 01 Disc comes in fours standard size (S, S/M, M/L & L) and only in stealth black, but includes five sticker packs to add a touch of color in the logos. Get one now from your local BMC dealer.
