Description

The Kool-Stop KS-D241S is a sintered disc brake pad engineered for Hayes Stroker Ace 4-piston calipers. Built with a copper-plated backing plate and a sintered friction compound, these pads are designed to handle the kind of punishment that aggressive descents and demanding conditions throw at them — making them a strong choice for riders who push hard on steep technical terrain.

Our Take

For riders tackling the ghats around Pune, Lonavala, or Khandala, where long descents demand consistent stopping power even when rims run hot and hands start to fatigue, the KS-D241S delivers. The sintered compound maintains friction performance under sustained braking loads, and the copper-plated backing plate adds structural integrity where it matters. If you run Hayes Stroker Ace 4-piston calipers, this is a pad worth keeping in your toolkit before every big ride.

Sizing for Indian Riders

These pads are caliper-specific — they fit Hayes Stroker Ace 4-piston systems only. There is no size variation by rider weight or build. Riders in high-humidity regions like Kolkata or coastal Chennai should note that sintered compounds handle moisture and heat particularly well compared to organic alternatives, making them suitable year-round including through the monsoon season.

Compatibility Notes

Designed exclusively for Hayes Stroker Ace 4-piston disc brake calipers. The spring is included. Not compatible with other Hayes caliper models or third-party 4-piston systems. Clean rotors with isopropyl alcohol before installation. Bed in pads properly with a series of progressive stops to achieve full contact and consistent braking performance.

Pairs Well With

Complete your braking setup with compatible disc brake rotors, hydraulic brake fluid, brake bleed kits, and rotor truing tools. Riders doing sustained descents in Coorg or Ooty will also want to look at heat-management accessories and lever upgrades that complement high-performance pad compounds.

Frequently Asked Questions

What is the Kool-Stop KS-D241S best used for?

The KS-D241S is best suited for aggressive mountain biking and downhill riding where sustained braking over long descents is required. The sintered compound resists heat fade and performs reliably in wet, muddy, or dusty conditions — making it a strong choice for riders on technical ghat routes around Pune, Lonavala, or Coorg where braking demands are high.

What size Kool-Stop KS-D241S should I order?

There is no size variation for these pads — they are designed to fit Hayes Stroker Ace 4-piston calipers only. Simply confirm that your brake caliper is the Hayes Stroker Ace 4-piston model before ordering. One pair is included per pack. If you need help identifying your caliper, the Cobbled Climbs team is happy to assist.

Will the Kool-Stop KS-D241S hold up in monsoon conditions and Indian heat?

Yes. Sintered brake pads like the KS-D241S are specifically formulated for demanding environments including wet monsoon conditions and high-heat riding above 35°C. Unlike organic pads, sintered compounds do not degrade as quickly when exposed to water, mud, or heat, making them well suited to Indian riding conditions across all seasons.

How does the KS-D241S compare to organic disc brake pads?

Sintered pads like the KS-D241S offer superior durability, better heat resistance, and more consistent performance under extreme conditions compared to organic pads. Organic pads tend to feel slightly more progressive and quiet initially but wear faster and can fade under sustained braking. For downhill use or heavy riders on long descents, sintered compounds are generally the better long-term choice.

Is the Kool-Stop KS-D241S worth the price in India?

For riders running Hayes Stroker Ace 4-piston calipers, the KS-D241S offers genuine value through its durability and all-condition performance. Sintered pads last significantly longer than organic alternatives in Indian conditions. Cobbled Climbs offers free delivery on orders above Rs. 2,500 and cash on delivery across India, making it easy to keep a spare set on hand.
