Description:
01 / ALL-ROAD INTENT
From smooth tarmac to rougher roads
S4.A is for riders whose routes include deteriorating pavement, firm gravel connectors and longer endurance rides but who still want the speed and responsiveness of a carbon wheel. Its 30 mm outside rim width and slightly shallower 42 mm profile position it differently from the 45 mm road S4.
03 / SPORT ESSENTIALS
Technology you can rely on.
The following systems are part of the Sport wheel engineering described by Scope. Product-specific hardware, fit and limits are detailed in the technical reference below.
SPORT 3-PAWL HUB
The established Sport hub mechanism differs from the Diamond Ratchet used in the newer R-Series models.
SAPIM CX-LEADER
Scope uses reliable steel aero spokes for a practical carbon-wheel construction.
LOCAL REINFORCEMENT
Extra carbon is placed at selected high-stress areas of the rim rather than increasing material throughout the whole structure.
THE SCOPE RANGE / THREE DISTINCT APPROACHES
Find your place in the Scope family.
Sport, Race and Artech share Scope's focus on carbon wheel performance. The difference is in the construction, technology and application; always compare the exact models and compatibility before choosing.

Scope wheelset / Compatibility answers
Frequently asked questions about Scope S4.A
Is the Scope S4.A the same wheel as S4 Disc?
No. S4.A has a 42 mm profile, 21 mm internal channel and 30 mm optimum tire. S4 Disc is a 45 mm road wheel with a 19 mm inner rim targeting 25 mm tires.
What is included in the Scope S4.A listing?
Complete disc-brake front-and-rear wheelset. Tires, cassettes, rotors and accessories are included only if specifically listed in the Scope package details.
What does the Scope S4.A weigh?
Scope publishes 1,622 g as its wheel weight. It is not a shipping-package weight, and actual manufactured weights can vary.
Which tire should I use with the Scope S4.A?
Scope identifies a 21 mm internal rim and 30 mm optimum tire width. The tire manufacturer must approve the tire on this particular rim width and bead system, and the frame must provide adequate clearance.
Will it fit my bike?
Check the axle standard, brake interface, tire clearance, and any rear cassette/freehub compatibility. A wheel-model name is not enough to establish drivetrain compatibility.
Can Brimstone help confirm compatibility?
Yes. Brimstone Bicycles can help you check rim/tire approval, axle type and—when applicable—the correct freehub body before you order.
