The ABEC 5 MRA 2437 bearing raises the bar for military standard, high precision bearings. Featuring HRC-64 hardened Chromium Steel Balls, and 52100 High-Carbon Chromium-Alloy mirror polished races, this model operates without any noise. The stunning ball retainers allow virtually frictionless movement and provide constant lubrication to maximise the life of this bearing. Technologies: Kyodo Yushi PS-2: This grease has a protective interface between ceramic balls and metal races and for it’s high speed properties and minimum rolling resistance. Speed and Protection for high precision bearing systems. LLB Seals: Two NBR 70 rubber seals with low contact seal, which rides in a matching groove machined into the bearing for low drag or friction.
The ABEC3 6806 LLU Max raises the bar for military standard, high precision bearings. This MAX model was engineered without retainers and 40% more balls than standard ABEC 3 or 5 bearings, enabling them to carry a much higher load and perfect for frame pivots. This bearing is packed with CRC Marine Grease, which will not wash out or break down when wet ensuring your frame bearings last longer than ever before. Technologies: LLB Seals: Two NBR 70 rubber seals with low contact seal, which rides in a matching groove machined into the bearing for low drag or friction. CRC Sta-Plex Marine: This grease will not wash out or break down under any extreme conditions including power washing, salt water intrusion from the salted roads, or even dirt getting into the rolling areas. The High Pressure properties of this grease provides a cushion for the sharp blows that suspension pivots will endure. Tough and Tenacious for high impact and extreme conditions.
The Wave pattern applies alternating lateral force to each chain link to actively retain links to the ring - going beyond narrow/wide implementation that relies solely on friction. MRP’s Wave tooth pattern swings right to left, grasping the interior of the chain for retention, but allowing room for mud, debris, and grit to escape. The Wave design creates more open areas for mud and debris evacuation and preserves chain retention in adverse conditions - one of many “Achilles’ Heels” of narrow/wide designs. Designed with mindful consideration of system friction, the Wave design actively engages the chain but yields much less concentrated wear than competing designs, spreading the load over large surface areas instead. Machined from durable, long-wearing 7000-series aluminium. Wave Chainring Technology Advancements The MRP Wave chainring technology utilises a host of features to provide robust chain handling and retention characteristics while providing market-leading durability. - 50mm (standard). - Tooth faces displaced from nominal centreline to provide active and positive lateral engagement of every chain link with a chainring tooth. - Alternating lateral force to each chain link to actively retain links to the ring. - Less surface contact between chainring and chain creating minimal friction and maximum retention. - Equal tooth thickness on the entire chainring to allow for maximum mud-shedding clearance. - Tooth design allows for reduced weight chainrings over competitor technology.

This stunning chainring grips your chain perfectly, prevents chain drops and will increase the confidence you have in your bike's drivetrain. Thanks to its ovalised design, you'll benefit from easier pedalling when your leg is at its maximum power output and a smoother power balance when your legs are at the weakest point in their rotation.
This stunning model is constructed from strong CNC'd 7075 T6 aluminium and has been specifically built for use with Shimano's XT M8000 cranks. Lightweight and reliable, this version shows off a highly praised tooth profile that's specially designed for 1x drivetrains. By adding a more constant torque to your rear wheel, you'll benefit from maximised traction and grip during climbs while also eliminating the chance of stalls and spinouts.
Pushing you on with precision, this Blackspire Snaggletooth chainring features a tough aluminium build. This makes it perfect at handling all the abuse that the woodland throws at you as you blast over rock gardens, tree roots and debris with style. Blackspire has also raised the bar by putting this sleek model through a CNC-machining process which shaves off any unnecessary weight. This allows you to enjoy its incredible strength without weighing down your ride with excess grams. Ovalised MTB Chainring Designed for ease of use, this ovalised chainring grants the benefit of making it easier to pedal when your leg is at its maximum power output. It also creates a smoother power balance when your legs are at the weakest point in their rotation. The power going to your rear wheel will be linear, making traction consistent, in turn making it less likely to lose power or spin your wheel on hard climbs by avoiding the dead spot in your pedal rotation.
Manufactured from steel with a black anodised finish.
This superb model is machined from AL7075-T6 and is ramped and pinned to ensure that shifting is precise and smooth with no chain suck. Additionally, its pins are stainless steel, which resists corrosion.
Designed for versatility, this model uses Wolf Tooth's renowned Drop-Stop technology, which improves chainring life and allows clearance for mud and debris. This makes it a great choice of upgrade for riders who want greater strength and reliability on every ride. Wolf Tooth was first to market with Cyclocross 1x specific chainrings because we saw Cyclocross as the perfect use for our Drop-Stop® technology. Since their release, the uses for these rings has expanded beyond Cyclocross to commuting, gravel riding, mountain bikes with 5-arm crank power meters, and even full on-road applications with the giant 50t rings. Drop-Stop technology. On Wolf Tooth’s patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction. Alternating wide/narrow tooth pattern prevents chain derailment. Compatibility: These rings are for use with 110 BCD 5 arm cranksets. Stock 2x bolts will not work. You will need bolts like Wolf Tooth's 6mm bolts which are optimized for single ring mounting. Chainline - varies - these rings can be mounted in either the big or small ring position on a double cranksets. The most common mounting is in the big ring position because of chainstay clearance. The ring centerline is ~2mm from the ring's mounting face so they usually sit about 2mm closer to the frame than the stock big ring (depends on the stock ring).
Whether you're pedalling around the city or exploring the countryside, this versatile component is designed to give you maximum performance. Equipped with a patented Drop-Stop technology, this model's wide side of the tooth has superior contact on the drive side which spreads the loads and improves chainring life. Its narrow side allows clearance for mud and debris which reduces friction, so you can benefit from a more reliable chain engagement as you move. Compatibility: - All sizes compatible with Dura Ace 9000, Ultegra 6800, 105 5800, RS510, Tiagra 4700 or 4703, Sora R3000 or R3030, and Claris R2000 or R2030 cranks. - 38-50T are compatible with 105 R7000, Ultegra R8000, and Dura-Ace R9100. The 36T chainring is NOT compatible with these cranks. - Size 42T and larger will work with the Dura Ace 9100 power meter.
Specially developed to fit Blank Compound hubs on Blank Compound wheelsets, this kit contains three pawls and one spring.
