Recommended Additional Upgrades
The RCB E3+ (E3 Plus) is the mid-range heavy-hitter in the RCB “Plus” family. It sits strategically between the E2+ and the E4+, offering a balance of refined ergonomics and improved fluid displacement.
Like its siblings, the E3+ is a CNC-machined master pump that focuses on durability and a “premium” cockpit feel.
Key Features of the E3+
-
14mm Piston Bore: While it shares the 14mm piston size with the E2+, the E3+ is often tuned for a slightly different stroke feel, providing a consistent and reliable pressure for single-caliper setups.
-
CNC Alloy Body: The body is fully machined from high-grade aluminum, offering better heat dissipation and a much cleaner look than cast-iron stock parts.
-
Adjustable Reach: It features a 6-stage adjustable lever, allowing you to fine-tune how far the lever sits from your handlebar. This is a game-changer for riders with smaller hands or those who prefer a specific “trigger” point.
-
Refined Reservoir Design: It typically features the signature transparent integrated tank, but with the updated “Plus” series styling—cleaner lines and a more “square-cut” aesthetic compared to the older rounded E2.
How it Fits the Lineup
Choosing between the “Plus” models usually comes down to your specific brake setup:
-
E2+: The entry-level CNC upgrade. Great for standard commuter bikes.
-
E3+: The “balanced” choice. It offers the same 14mm pressure as the E2 but often with a more robust body design and better lever ergonomics.
-
E4+: The “performance” choice. With its 15mm piston, it is designed for those who want a stiffer, more aggressive bite or are running larger calipers.
Performance Insight
The E3+ is perfect for riders who want the aesthetic of a high-end racing pump but don’t want the “on-off” twitchiness of a larger 15mm piston. It keeps the braking feel progressive, making it very safe for wet weather or heavy city traffic where you need to modulate your braking force carefully.
