Marginal gains for SRAM’s direct-mount Eagle drivetrains <\/p>

CeramicSpeed has launched a new Oversized Pulley Wheel System designed specifically for SRAM\u2019s Eagle Transmission drivetrains.<\/p>\n

According to CeramicSpeed, the OSPW X for SRAM Eagle Transmission offers improvements in both efficiency and durability.<\/p>\n

The design is based on CeramicSpeed\u2019s new \u2018Further Drive\u2019 technology. This comprises of the \u2018Active Debris Remover\u2019 and \u2018Alpha Disc\u2019 two-piece construction.<\/p>\n

CeramicSpeed\u2019s OSPW systems are relatively common on pro-level WorldTour road bikes, but less so on high-end mountain bikes. Oversized pulley wheel systems are typically accompanied by claims of reduced drivetrain friction and, as a result, improved efficiency.<\/p>\n

Here, however, CeramicSpeed has taken an oversized system and focused on \u201cthe robustness that the Eagle Transmission group is celebrated for\u201d.<\/p>\n

The \u2018Active Debris Remover\u2019 encloses the bearing, according to CeramicSpeed, with a \u201cnew dust cover design that sits safely anchored in a groove in the pulley wheel. This is paired with a bladed groove structure that surrounds the dust cover, which dynamically extracts debris from the pulley wheel when it\u2019s rotating\u201d.<\/p>\n

CeramicSpeed says a prototype version was tested at this year\u2019s Cape Epic XC marathon race.<\/p>\n

\u2018Alpha Disc\u2019, meanwhile, is a 20-tooth solid disc pulley wheel. It\u2019s a two-piece construction, combining the narrow-wide tooth profile \u2013 apparently made from a \u201ccomposite material that offers prolonged wear protection and noise reduction\u201d \u2013 with a solid aluminium disc.<\/p>\n

This, according to CeramicSpeed, eliminates the potential of external objects getting stuck between the spokes of the pulley wheel.<\/p>\n

While CeramicSpeed offers an OSPW Aero system<\/a>, this new Eagle design isn\u2019t accompanied by any aerodynamic claims. \u201cOur development and focus for Alpha Disc was specifically related to the functional attributes and protection afforded by the solid pulley disc,\u201d says CeramicSpeed.<\/p>\n

SRAM\u2019s Eagle Transmission drivetrain was first introduced in March<\/a>, utilising a direct-mount rear derailleur design that removes the derailleur hanger from the equation.<\/p>\n

SRAM says it honed in on the durability of the design, with user-replaceable components, such as the cage, Skid Plate and outer parallelogram links.<\/p>\n

The toothed outer portion of the Eagle Transmission derailleur\u2019s lower pulley wheel can also rotate independently from the spoked centre section. If blocked, the outer portion of the pulley continues to rotate on the stationary centre\u2019s spokes, reducing the chances of chain jam and damage.<\/p>\n

While the stars of CeramicSpeed\u2019s show are the solid-spoked jockey wheels, a new carbon fibre derailleur cage is also included.<\/p>\n

\"CeramicSpeed\n<\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/picture>\n<\/div>
The system is available in two colours: silver and black.<\/span><\/figcaption> CeramicSpeed<\/i><\/span><\/div>\n

According to the brand, the cage uses a weightier construction \u201cwithout adding unnecessary bulk\u201d.<\/p>\n

Presumably, however, the need for an updated cage is to accommodate the massive 20-tooth lower jockey wheel, up four teeth from the standard wheel.<\/p>\n

CeramicSpeed is quick to claim the carbon cage is \u201cin line with the robustness\u201d of a standard Eagle Transmission.<\/p>\n

CeramicSpeed\u2019s new OSPW X system is compatible with XX SL, XX, X0 and GX versions of Eagle Transmission.<\/p>\n

It runs with a 10-52t cassette and the oversized pulley systems weighs a claimed 110g, according to CeramicSpeed.<\/p>\n

OSPW X for SRAM Eagle AXS Transmission costs a cool \u20ac579 \/ $669, comes in two colours \u2013 black and silver \u2013 and is available now.<\/p> <\/body><\/html>\n
