Looking for a Pro experience on all roads and more? The Diverge STR is here to carry you to more places, more comfortably, whether loaded up, or built to race. It is a game changing solution for those who seek the greatest efficiency, control, and ride quality in a gravel / adventure bike. Specialized tossed status quo out the window to deploy a progressive gravel geometry that amplifies the confidence that Front and Rear Future Shock Technology delivers. It’s the most elegant, adjustable, and seamless solution to Suspend The Rider the folks in Morgan Hill have ever created. And this from the company that offers Epic BRAIN technology. With this 2023 Diverge STR Pro Carbon Bicycle featuring a ride ranging SRAM Force/X01 Eagle AXS drivetrain and HRD disc braking, you can pedal as hard or as far as you want, and fully enjoy the riding experience.

All the R&D, brainwaves, and testing of all kinds that drove the Diverge STR design can be read about elsewhere, but suffice to say the result is what you see today, a Diverge STR with front and rear Future Shock. As a system, Rear Future Shock delivers up to 30mm of travel in the perfect curve, is fully tunable for riders from 110lbs to 275lbs, features hydraulic damping to control travel, and has 3 levels of adjustability, as well as rebound adjustment. To provide the right “spring” for every rider, each bike size comes with two different frame posts, and each frame post can be oriented in a stiffer or softer orientation. While the vast majority of riders will find the perfect setup with the posts that are included with their bike, Specialized makes nine different posts, each with a soft and firm setting, so every rider can experience the incredible ride Diverge STR delivers. This framepost works with the seat post to provide the optimal amount and path of rear travel for every rider, regardless of their bike size, weight, or the length of exposed seat post. Riders can even dial in the optimum level of compliance with an alloy dropper post, thanks to the Future Shock Rear system. Future Shock Rear travel is controlled by a hydraulic damper fitted in the top tube and attached to the frame post by the “tendon”. A lever on the damper provides three levels of compression damping, while rebound speed can be adjusted with a hex key through a hole in the base of the top tube. Yes, there is some testing and set-up for you to work through, just as there is with a mountain bike, but it is simple, and most riders won't make many adjustments once they feel right.

Keep in mind this Diverge STR Pro is still a Diverge, with largely the same geometry, and the same great, tunable Future Shock 2.0 and SWAT storage- just made even more capable as an STR.

  • Front and Rear suspended Diverge developed to be even more versatile, efficient and effective on more surfaces and in all conditions
  • Built here in a complete Pro package featuring a Force/X01 Eagle AXS "mullet" drivetrain for massive gearing range and overall capability
  • STR: Suspend The Rider concept to keep riders comfortable and in control on rough "roads", and retain the instant acceleration and direct handling of a rigid frame
  • Adjustable, damped, tunable travel- 20mm front/30mm rear- Future Shock Technology absorbs bump forces to boost your control and capability while retaining efficiency/responsiveness of a rigid frame
  • Future Shock 2.0 front with 20mm of adjustable response
  • Rear Future Shock system for 30mm of travel that you can adjust for flex, compression, damping
    • RFS components and basic functions
    • 1- Framepost: Acts as a Spring; as the rear wheel impacts a bump, it moves up- the ‘framepost’ works a spring moving backwards in response; direction of travel is equal and opposite to the wheel’s path
    • 2- Damper: Controls the movement of the framepost spring action backwards and forwards, ensuring a smooth ride
    • 3- Compression Adjustment Lever: Allows for manual adjustment at 3 levels of damping rate; rebound is adjustable via hex key
    • 4- Tendon: Connection part that ties framepost and damper together
  • Frameposts available in 9 lay-ups that each can be clocked to offer a softer or firmer ride within a stiffness range
  • Each frame/bike comes with 2 frameposts dictated by frame size and average expected rider weights; others can be purchased separately
  • Seven of the frameposts can be used with 52-61cm sizes, the 49cm has two specific options (FP8/FP9)
  • Numbers on either side of the arrows indicate the frame post’s stiffness; arbitrary measurement- indication of the stiffness in N/mm (ex- a FP might offer 30N/mm or 60N/mm (twice as stiff) by the way it is installed
  • Alloy dropper posts are compatible with the RFS system
  • System weight: 275lbs (rider/gear)
  • Frameposts by N/mm / System weight range: FP: 30|38 / 110-160lbs, FP2 35|43 / 135-180lbs, FP3 40|48 / 150-200lbs, FP4 45|53 /165-210lbs, FP5 50|58 175-230lbs, FP6 55|65 / 205-255lbs, FP7 60|72 / 215-275lbs, FP8 28|34 / 110-155lbs (49cm only), FP9 40|48 / 155-275lbs (49cm only)
