700 Series OCLV Carbon Aero Race Frameset with Adjustable IsoSpeed

The Trek Madone SLR Gen 6 BB90 Rim Frameset is a lightweight aero road race frame built from 700 Series OCLV Carbon - a higher-grade construction than the 500 or 600 Series used in lower-tier Madone models, delivering a more performance-focused blend of stiffness, weight, and compliance. The SLR designation places this frameset at the top of the Madone Gen 6 lineup, representing Trek's highest-grade carbon construction and most advanced frame technology available in the Gen 6 generation.

This is a rim brake frameset - an important specification for riders building on a classic rim brake platform who prefer the weight and simplicity advantages that rim brakes provide over disc alternatives. The BB90 bottom bracket standard is Trek's proprietary interface, requiring BB90-compatible cranks or an appropriate conversion sleeve when building with third-party drivetrain components.

As a custom build platform, the Madone SLR Gen 6 frameset accepts a wide range of component choices. The availability of Madone Project One ICON paint schemes - mentioned in the manufacturer's information - reflects the frameset's heritage as a custom build canvas as well as a race-ready performance platform.

• Madone Gen 6 takes tried-and-true road-smoothing IsoSpeed comfort technology and bundles it into a lightweight, race-ready package for fast rides
• Adjustable Top Tube IsoSpeed lets you adjust compliance to your preference, and it's damped with an elastomer so it rebounds in a smooth, controlled, stable motion
• Let's be honest: this bike looks awesome, like it's breaking speed records even when it's parked at the café for a post-ride espresso
• Madone Project One ICON paint schemes make the ultimate race bike a true piece of artwork

Adjustable Top Tube IsoSpeed with Elastomer Damping

The Madone SLR Gen 6 features IsoSpeed technology with a distinguishing upgrade over standard IsoSpeed implementations - the Top Tube IsoSpeed is adjustable. Riders can dial in the compliance level to their personal preference rather than accepting a fixed compliance setting, allowing the frameset to be configured for either more compliance on rough or long courses or stiffer response on smooth, sprint-focused riding.

The adjustable IsoSpeed system uses an elastomer to control the rebound of the compliance movement. Rather than allowing free, uncontrolled flex that could feel wallowy or unpredictable, the elastomer ensures the frame's compliance motion rebounds in a smooth, controlled, and stable way. This damped rebound means the IsoSpeed system absorbs road input and returns without oscillation or a secondary bounce that would interfere with pedalling efficiency or handling stability.

For riders who race on varied course profiles - smooth tarmac criteriums one weekend, rough cobbled gran fondos another - the adjustable compliance means the frameset can be configured appropriately for the event rather than being fixed at a single compliance setting that is a compromise across all conditions.

Aero Performance, Race Geometry, and Project One Availability

The Madone SLR Gen 6 is built around the aero tube shapes and race geometry that defined the Gen 6 Madone's competitive identity. The frame is designed to be fast - aerodynamically, in terms of weight, and in terms of the handling precision that race geometry provides. Trek describes the bike as looking like it is breaking speed records even when stationary - a reflection of the tube shapes and overall visual identity that communicates speed through the frame's silhouette.

Project One ICON paint scheme availability makes this frameset a candidate for a fully custom visual build as well as a performance one - relevant for riders who want their race bike to be a personal expression as well as a competitive tool. The Project One programme allows bespoke colour schemes beyond the standard catalogue finishes.

FAQs

What carbon grade is used in the Madone SLR Gen 6 Frameset?

The frameset is built from 700 Series OCLV Carbon - Trek's highest-grade carbon construction used in the SLR tier of the Madone lineup.

What bottom bracket standard does the Madone SLR Gen 6 BB90 use?

The frameset uses BB90 - Trek's proprietary press-fit bottom bracket standard. Cranks must be BB90 compatible or use an appropriate conversion sleeve.

Is this frameset rim brake or disc brake?

This is a rim brake frameset. It is not compatible with disc brake callipers or disc brake wheels.

What is the adjustable Top Tube IsoSpeed on the Madone SLR Gen 6?

The adjustable Top Tube IsoSpeed allows the rider to set their preferred compliance level rather than accepting a fixed setting. An elastomer controls the rebound motion, ensuring the compliance movement is smooth, controlled, and stable rather than uncontrolled or bouncy.

Are components included with the Madone SLR Gen 6 Frameset?

No. This is a frameset only. All components including the fork, drivetrain, wheels, cockpit, and bottom bracket must be sourced separately.

Is the Madone SLR Gen 6 available in Project One custom paint?

Yes. Madone Project One ICON paint schemes are available for this frameset, allowing fully custom colour configurations beyond the standard catalogue finishes.

How does the Gen 6 Madone SLR differ from the Gen 8 Madone SLR?

The Gen 6 uses 700 Series OCLV Carbon, rim brake, BB90 bottom bracket, and adjustable Top Tube IsoSpeed. The Gen 8 uses 900 Series OCLV Carbon, disc brake, a different bottom bracket standard, and Full System Foil aero tube shaping with refined IsoSpeed. The Gen 6 is a previous generation platform that suits riders who prefer rim brake or want a Project One custom build from this generation.
