Product Details

Overview & Technology

Eclypse W1 pads pair a semi-metallic friction compound with a full steel backing plate to deliver consistent braking across varied conditions. The semi-metallic blend balances initial bite, modulation and durability — giving confident stops on wet, muddy or dry trails and roads. Construction matters: the steel backing plate stabilizes the pad under load, improves heat transfer away from the friction surface and reduces flex that can cause inconsistent lever feel. The W1’s pad shape is specified as Clarks Mechanical, making these a direct replacement option for Clarks CMD-5 and CMD-7 mechanical disc calipers. Shipping dimensions are compact (6" x 4.2" x 0.3") and each package is very light (0.07 lb), ideal for stocking spares.

Key Features & Real-World Benefits

Semi-metallic compound: engineered for strong bite and fade resistance. Metal particles in the matrix raise thermal capacity so braking performance stays predictable on long descents and under repeated stops. • Consistent stopping power: reliable performance in both wet and dry conditions. • Improved modulation: easier to feather brakes for speed control on technical terrain. • Durability: semi-metallic pads tend to resist glazing and last longer than organic compounds in abrasive or muddy environments.

Fit, Compatibility & Installation Notes

The W1 pads are shaped for Clarks mechanical caliper profiles and listed as compatible with Clarks CMD-5 and CMD-7 mechanical disc brake models. They come with a steel backing plate that matches standard mechanical caliper retention systems used by Clarks. When installing, check pad-to-rotor clearance, ensure the caliper is centered, and follow a standard bedding-in procedure (a series of progressive stops from moderate speed). These pads are designed for metal-backed pad holders; if your caliper uses a different retaining system or spring orientation, confirm fit before purchase.

Who These Pads Are For

The Eclypse W1 is aimed at mountain and all-terrain riders who want a durable, high-bite pad that performs in mixed conditions without the premium price of sintered race compounds. They're an excellent choice for trail riders on budget-friendly builds, commuters who face wet weather, and any cyclist running Clarks CMD-series mechanical calipers. If you prioritize low noise above all else or run high-end hydraulic systems, consider pads tailored to those setups. For riders who want dependable stopping, extended pad life and robust thermal behavior on long descents, the W1 is a practical upgrade or spare set to keep on hand.

Frequently Asked Questions

Will these pads work in hydraulic calipers?

No — the W1 pads are shaped specifically for Clarks mechanical calipers (CMD-5 and CMD-7). Hydraulic calipers typically use different pad shapes and retention hardware, so confirm pad shape compatibility before installing in hydraulic systems.

How do I bed in the Eclypse W1 pads?

Bedding in improves pad/rotor contact and initial performance. Perform 8–10 progressive stops from a moderate speed (walk-up to ~20 km/h), avoiding complete lockups. Allow the brakes to cool between heavy stop sets. This deposits an even transfer layer for consistent bite.

Are semi-metallic pads noisier than organic pads?

Semi-metallic pads can be slightly louder under some conditions due to the metal content, but they provide better heat management and durability. Proper rotor condition, alignment and bedding-in will minimize noise.

How often should I replace the W1 pads?

Replacement intervals depend on riding style, terrain and contamination. Check pad thickness regularly; replace when friction material approaches 1 mm or if you notice reduced performance, scoring, or contamination. Aggressive or muddy riding wears pads faster.

Do these pads require specific rotors?

W1 pads are compatible with standard steel disc rotors used on mechanical systems. For best results, pair them with clean, undamaged rotors of the correct thickness and finish. Avoid mixing very hard rotors and soft compounds if excessive wear is a concern.

Can I use these pads in wet conditions?

Yes — the semi-metallic compound is formulated to maintain strong bite and consistent modulation in wet and muddy conditions, making the W1 suitable for year-round riding.

Buying Guide

When buying replacement disc brake pads for mechanical calipers, confirm the pad shape and retention style match your caliper model. Choose a compound based on your riding: semi-metallic for durability and wet-weather performance, organic for quieter, more progressive feel, and sintered for heavy-duty heat resistance. Also inspect your rotors and callipers — warped rotors, uneven pistons or contaminated surfaces shorten pad life and reduce braking effectiveness. Always replace pads as a matched pair on each wheel and carry spare pads on longer rides for peace of mind.
