Strummer Traverse CF2 is designed to deliver optimal performance in a variety of conditions, from paved roads to gravel routes and rocky roads.
The frame and fork use Toray T800 carbon fiber to provide a combination of stiffness, strength, light weight, and riding comfort.
The asymmetric chainstay design helps increase stiffness on the drivetrain side, maintain stability on the non-drive side, and provide more optimal clearance for chainring use.
The top tube features a Vibration Dampening Zone designed to help reduce vibrations from the road surface, improving comfort when riding over rough roads or long-distance gravel routes.
Integrated Downtube Storage
Traverse CF2 is equipped with internal storage in the downtube for carrying an inner tube, tire levers, repair tools, a compact pump, or other small equipment.
A special storage bag that fits inside the downtube is included with the purchase.
Fully Internal Cable Routing
The fully internal cable routing system in the frame and fork creates a cleaner, neater appearance.
Traverse CF2 is compatible with mechanical, Shimano Di2, and SRAM AXS groupsets. The frame also supports a dropper post with internal cable routing.
The product is sold as a frameset consisting of the frame and fork.

Chainring Compatibility
| Crankset Brand | Configuration | Maximum Size |
|---|---|---|
| Shimano | 2x | 54/40T |
| Shimano | 1x | 42T |
| SRAM | 2x | 54/41T |
| SRAM | 1x | 42T |
For 2x configurations, the numbers indicate the maximum outer and inner chainring combination. For example, 54/40T means a maximum 54T outer chainring and 40T inner chainring.
Smaller chainrings can generally be used. Final compatibility still depends on the crankset model, chainline, chainring offset, spindle length, front derailleur position, and safe clearance between the chainring and chainstay.

Product Weight
Actual weight may vary depending on frame size, color, and the number of finish layers.
Weight of Size 52 Frame ±1.15 kg
Fork Weight ±0.55 kg (including thru axle)
Because the carbon frame and fork undergo production and finishing processes involving manual work, slight variations in weight and finish appearance may occur between products.
Tire Compatibility Notes
Maximum tire clearance can be affected by:
-
Actual tire size after installation
-
Internal rim width
-
Tire casing shape and tread pattern
-
Air pressure
-
Production tolerances of each tire brand
Tires with the same labeled size do not necessarily have the same actual width after installation. Ensure there is adequate clearance between the tire and the frame and fork before riding the bike.

Size Selection Guide
| Size | Recommended Rider Height | Estimated Minimum Inseam |
|---|---|---|
| 490 / Small | 165–174 cm | Approximately 79 cm |
| 520 / Medium | 172–180 cm | Approximately 81 cm |
| 550 / Large | 180–186 cm | Approximately 85 cm |
The height ranges overlap because size selection is also influenced by inseam length, torso, arm length, body flexibility, and the desired riding position.
Prioritize inseam length and standover clearance. As a guide, allow approximately 20–30 mm between the crotch and the top tube when standing over the bike.
If your height falls within an overlapping range:
-
Choose the smaller size for a lower position and more agile handling.
-
Choose the larger size for a higher front position and more stable riding characteristics.
Stem size, crank length, handlebar width, spacer amount, and saddle position can also affect comfort and riding position.
Installation and Usage Notes
Use a torque wrench when installing components on the carbon frame and fork. Do not exceed the torque limits specified by the frame or component manufacturer.
The installation torque limit for the front thru axle is 10 Nm.
Frameset and component installation should be performed by an experienced bicycle mechanic.
