BMC Time Machine Road 01 Sram Force E-Tap

by Hepzi Jasmine November 19, 2025 1 min read

The BMC Timemachine Road 01 SRAM Force eTap AXS represents the top tier of BMC’s aero road engineering — designed to deliver maximum aerodynamic gain for competitive riders and speed-focused endurance athletes. Marketed as a pure “wind-cutting performance machine,” it combines a highly advanced TMR01 carbon frame, fully integrated cockpit, and SRAM’s wireless electronic drivetrain. My evaluation focused on understanding how these technologies translate into real-world speed, comfort, and control.

“This isn’t just a bike — it’s engineered to turn every pedal stroke into uncompromised velocity.”

: The core of the TimeMachine Road 01 is its TMR01 aero carbon frameset — an ultra-refined structure using truncated airfoil profiles, deep headtube shaping, and an integrated cockpit that removes visible cables from the wind. The geometry leans toward an aggressive aero fit, ideal for racing or high-speed endurance riding, while still maintaining some compliance for longer days in the saddle.

“Each aero tube surface is shaped for one objective — to reduce drag and preserve pure speed.”
: This model is equipped with SRAM Force eTap AXS 2×12, a fully wireless electronic system that stands out for its smooth, crisp shifting and clean cockpit appearance. The drivetrain usually pairs a 48/35T crankset with a 10–33T cassette, giving wide gearing for both high-speed efforts and steep climbs.

"
“Wireless precision ensures every shift is fast, fluid, and perfectly in sync with your effort.”
: Despite its status as a speed-first aero bike, the Timemachine Road 01 delivers respectable comfort for endurance riding. The carbon layup strategically absorbs vibration, especially in the seatpost and stays, reducing fatigue on medium/long rides.

The stock 700×28C tyres provide a balance between speed and cushioning, and upgrading to 30 mm enhances comfort without affecting aerodynamics significantly. The wide tyre clearance is an underrated advantage, especially on uneven or poorly paved Indian roads.

"
“With modern tyre clearance and tuned carbon flex, it smoothens the ride far more than traditional aero bikes.”
: Braking is handled by SRAM Force hydraulic disc brakes, which provide strong bite, smooth modulation, and predictable stopping power even at high speeds. Descents feel controlled, and braking distances remain consistent in wet or dry conditions.

"
“Reliable braking and razor-sharp steering make high-speed manoeuvring feel effortless.”
: Most builds of this model come with deep-section aero carbon wheels (often 50–60 mm), perfectly complementing the frame’s aerodynamic design. These wheels hold speed with remarkable momentum and feel exceptionally stiff during sprints.

“Deep aero wheels amplify the bike’s ability to maintain speed effortlessly on open roads.”
