The week leading up to the 2018 Tour de France has been packed with aero bike launches so far, with BMC now joining the Specialized Venge and Cannondale SystemSix aero party with the new Timemachine Road.
The new disc brake-only bike sits alongside the Teammachine as the brand’s go-to race bikes for the pro team, with the Teammachine all-rounder now more easily pigeon-holed as a climber’s bike, and the Timemachine taking over the aero reins.
The family resemblance to the Teammachine is undeniable, but at the Timemachine Road’s core is the Aero Module concept – a design that BMC engineers say practically eliminates ride-slowing airflow separation at low yaw angles around the bottle cage area.
BMC Timemachine Road models
BMC Timemachine 01 Road One (Shimano Dura-Ace Di2) - £10,000
BMC Timemachine 02 Road Two (SRAM Red eTap) - £8,500
BMC Timemachine 03 Road Three (Shimano Ultegra Di2) - £6,750
The cages are now recessed into the downtube and curved seattube, while underneath them BMC has taken a leaf out of Specialized’s book with its SWAT storage device and integrated a similar device around the bottom bracket area for aero gain and increased everyday storage potential. This ‘Aero Box’ is removable so that the bike complies with UCI fairing regulations.
The frame itself features Kammtail rear sections, and deeper section aerofoil downtube, seattube and headtube areas than the Teammachine. These profiles were chosen following extensive CFD research and wind tunnel testing, with BMC claiming “consistent and measurable power savings for all types of riders [over the Teammachine SLR01].”
Those claims are said to be corroborated by hours of real-world testing too, although BMC stops short of making specific claims.
Up front, a new ‘ICS Aero Cockpit’ minimises the front-facing profile while neatly integrating cable routing and a computer mount in a package that’s widely-adjustable to help the rider find their optimal position.
Real world speed
It’s clear that BMC has put a focus on achievable speed in the real world with the Timemachine Road, using the proven Tuned Compliance Concept technology to help balance the ride with compliance and road damping through the 01-spec carbon tubes. The ‘Speed’ iteration developed here is focused towards maximising power transfer and ride efficiency without sacrificing the bike’s aero prowess.
In addition to these specific compliance-improving yet stiffness-maintaining tube shapes in the frame and fork, there are dropped seatstays and a D-shaped seatpost for added rear end deflection, while the flattened aero stem also works to improve overall front end compliance.
Three bikes from £6,750
The Timemachine Road is disc brake-only, with three full-build bikes available along with a frameset ‘module’ including bar-stem setup, seatpost and saddle. Evans Cycles (BMC’s UK distributor) will provide all models, with prices starting from £6,750 for a Shimano Ultegra Di2 machine, before stepping up to a SRAM Red eTap bike with SRAM Red eTap for £8,500. A £10,000 machine with Shimano Dura-Ace Di2 tops the range.
