Shockingly light

A new gram-shaving design and lightweight 500 Series OCLV Carbon make Madone SL nearly 300 grams lighter than the bike that came before it. 

Thrillingly fast

Our fastest Madone SL ever clocks in at 54 seconds per hour faster* than the previous generation.

Remarkably smooth

Proprietary IsoFlow technology shaves weight, improves aerodynamics, and smooths fatiguing bumps in the road.

Extraordinarily aero

A flared, aero-optimized bar and stem, aerodynamic riding position, and newest generation of aero tube shaping cuts through the wind and puts you in the position for power.

Madone SL will be available globally on trekbikes.com and through Trek's global network of retail partners.

Anything I should know about the handlebar that comes on the complete bike?

The RSL Aero bar features a shallow reach, flared design for improved ergonomics and aerodynamics, just like the bar/stem on the Madone SLR. There are a few important fit-related items to keep in mind:
• Width on this bar is measured at the drops
• The tops are 3cm narrower than the drops
• Reach: 80mm
• Drop: 124mm

Example: Looking at a 42mm wide bar? That means the drops measure 42cm center-to-center and the tops – specifically the ‘Control Width’ where the levers are mounted – measure 39cm.

Is the RSL Aero bar compatible with aero extensions?

No. 

Are these bikes tubeless compatible? What additional parts are required?

The wheels are tubeless compatible, but the bike will ship with standard inner tubes and non-tubeless compatible tires and rim strips. Additional sealant and tubeless ready-tires, rim strips, and valve stems will be required to make the conversion to tubeless set up.

What stem and seatpost comes with a frameset only purchase?

Seatposts and stems are fit-specific items and not included with framesets.

What bearing cover comes with the frameset?

The one compatible with the Bontrager RCS Pro stem. Part numbers for bearing covers compatible with other stems can be found in the Madone SL service manual.
