Specialized Diverge 4 Pro LTD - Shimano XTR/GRX Di2
Limited Edition: Only 150 Bikes Worldwide
The Specialized Diverge 4 Pro LTD is a premium gravel bike created for fast racing, long-distance adventures and demanding mixed-surface riding. Its FACT 9r carbon frame combines Future Shock 3.3 suspension with SWAT 4.0 storage, while Shimano GRX and XTR Di2 shifting, a 4iiii power meter and Roval Terra CLX III wheels provide a genuinely high-performance build. With only 150 produced worldwide, this is also one of the most exclusive Diverge models available.
Responsive FACT 9r Carbon Frame
The FACT 9r carbon frame balances low weight, efficient power transfer and the durability needed for gravel riding. It responds quickly when accelerating or climbing while retaining the stability required for rough roads, loose corners and long days in the saddle.
A threaded bottom bracket simplifies servicing, while 12 x 142mm thru-axle spacing, a UDH dropout and internal cable routing provide modern and practical frame standards.
Future Shock 3.3 Control
Future Shock 3.3 provides 20mm of travel beneath the handlebars, helping isolate the rider’s hands and upper body from corrugations, potholes and repeated gravel impacts. The suspension operates above the head tube, allowing the front wheel and frame to remain directly connected for accurate steering.
Its adjustable and tuneable design helps reduce fatigue while allowing riders to maintain better control and speed across rough terrain.
Shimano GRX and XTR Di2 Shifting
The drivetrain combines Shimano GRX Di2 controls with an XTR Di2 rear derailleur and wide-range 10–51T cassette. Electronic shifting provides precise gear changes with minimal lever effort, while the mountain-bike-derived derailleur and cassette deliver the range needed for steep and loose gravel climbs.
A single 40-tooth chainring keeps operation simple and removes the weight and complexity of a front derailleur.
Easton EC90 ALX Power Meter Crankset
The Easton EC90 ALX carbon crankset reduces weight while providing efficient power transfer during hard accelerations and sustained climbing. Its integrated 4iiii power meter gives riders accurate information for pacing, training and measuring performance.
Power data can be particularly valuable during long gravel races, where controlling effort early can make a considerable difference later in the ride.
Roval Terra CLX III Carbon Wheels
Roval Terra CLX III wheels use lightweight carbon rims and composite spokes to reduce rotating weight and improve acceleration. Their 27mm internal width provides stable support for high-volume gravel tyres, improving cornering control and tyre performance at lower pressures.
The wheels are tubeless compatible and fitted with Specialized Tracer 700 x 50c tyres, creating a fast but capable setup for loose gravel, rough back roads and mixed-surface racing.
SWAT 4.0 Internal Storage
SWAT 4.0 provides internal storage within the downtube for tools, a tube and other ride essentials. This keeps equipment secure and accessible without requiring a saddle bag or overloading jersey pockets.
The larger storage capacity is especially useful for long-distance events and remote rides where carrying repair equipment is essential.

Our Thoughts on the Specialized Diverge 4 Pro LTD
The Specialized Diverge 4 Pro LTD is a particularly well-considered build for serious gravel riders. Its FACT 9r frame provides the responsive feel expected from a premium race bike, while Future Shock 3.3, 50c tyres and SWAT 4.0 storage make it practical for rough courses and long, unsupported rides.
The Shimano GRX and XTR Di2 drivetrain is a standout feature.
