A good choice for commuters, gravel riders, recreational mountain bikers and workshop replacements where your bike uses a compatible Shimano 2-piston caliper and you want quiet, controllable braking.
The Shimano BP-B05S-RX is a resin disc brake pad for a wide range of compatible Shimano 2-piston hydraulic and mechanical disc brake calipers. It is supplied as one pair, with a stainless back plate and a wide Type B pad shape. Check your caliper model before ordering, as the shape is specific to the listed Shimano systems.
The 5th-generation resin lining is tuned for lower noise and smoother modulation, giving you easier control when feathering the brakes in traffic, on descents or over loose surfaces. Customer feedback commonly highlights quiet operation, straightforward replacement and predictable everyday braking, although resin pads remain better suited to general riding than sustained aggressive braking or exceptionally demanding conditions.
The revised friction material offers 50% better wear resistance than B03S and 110% better than B01S, so these are a sensible upgrade when you want longer service intervals without moving to a metallic compound. They are listed for calipers including BR-MT500, BR-MT410, BR-MT400, BR-MT200, BR-UR300, BR-TX805 and many other Shimano 2-piston models.
5th-generation resin compound
Designed to reduce brake noise while providing smooth, predictable modulation at the lever.
Improved wear resistance
The updated friction material is rated at 50% better wear resistance than B03S and 110% better than B01S.
Wide Type B shape
A specific pad profile for compatible Shimano braking systems, so confirm your caliper model before purchase.
2-piston compatibility
Made for listed Shimano 2-piston hydraulic and mechanical disc brake calipers.
Stainless back plate
Provides a durable support structure behind the resin friction material.
No radiator fin
A simple, non-finned design suited to compatible standard brake calipers.
Quiet everyday performance
Resin construction is a practical option when low noise and easy modulation matter more than maximum heat resistance.

Shimano is a Japanese component brand founded in 1921 in Sakai, Osaka. The company began with bicycle component manufacturing and has grown into a global business focused on bicycle components, fishing tackle and rowing equipment, while keeping its headquarters in Sakai.
In cycling, Shimano is best known for building complete component ecosystems that span road, mountain, gravel, commuting and e-bike use. Its range covers drivetrains, brakes, wheels, pedals, shoes and related parts, and the brand has had a long presence in Australia through a local business established in Sydney in 1992.
