With precision sealed bearings and cold-forged, aluminum CNC machined cups, the Box One™ Titanium Square Taper bottom brackets are the best option for young BMX racers and other users. It is a three-piece crank in search of performance gains and weight savings. They have hollow, custom titanium-nitride-coated titanium spindles and carbon fiber center seals, helping keep the weight down between 185 and 190 grams (well below that of other square taper bottom brackets on the market). Other features include cups that are anodized black with anodized gold inner seals and a JIS tapered spindle that comes in either 108 or 113 millimeters. Weight Limit: 115kg (253 lbs) with limitations as per Category 2 of EN 16054:2012 Standard Features: - Precision Abec-5 Sealed Bearings - Lightweight Non-Structural Carbon Components - Extra Rigid Titanium Spindle Compatibility: - Box Five Square Taper Crankset Specs: Process: CNC-Machined Cups Material: - Spindle: Titanium - Cups: Alloy - Sleeve: Carbon Fiber Finish: Titanium Nitride Coated Spindle Type: JIS Square Taper Spindle Length: 108mm or 113mm Shell Width: 68mm Thread: 1.37" x 24 TPI Compatibility: BSA Threaded Weight [108-113] (+/- 5%): 199-204 g / 7-7.2 oz

This bottom bracket is perfect for when you have a PF30, BBright, or 386EVO shell frame and want to install a crank with a 30mm spindle into the frame. All these frame standards have a 46mm inner diameter and smooth insides, though the widths vary from 68mm to 86mm. This bottom bracket features nearly zero loss of power due to friction, thanks to the CeramicSpeed's incredibly efficient bearings. Choose either our Standard or Coated Bearings—both have super-round, super-smooth CeramicSpeed balls rolling on hardened-steel races. The Coated version has a metallic coating laid onto the races, making them even harder and smoother and resulting in longer life and lower drag. They come installed in cups. 30mm spindles on cranks are increasingly popular because of the high stiffness and low weight. 46mm inner diameter bottom brackets are popular for the freedom they offer designers in building frames. Because of the variety of widths, the cups here extend into the shell and come with a telescoping spacer tube to further seal and stiffen the system. The bottom bracket is already stiff thanks to hard ceramic bearings and hardened-steel races. Thanks to CeramicSpeed, it also generates nearly zero drag. Standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That's in the range of a 75% drag reduction versus conventional BBs. The bearings also last at least 3x longer than other bearings. You can change the grease to fine-tune your BB's performance characteristics. TT and Track, All Round, and LongLife are greases CeramicSpeed designed. The first has the least drag, while the last is the most durable. All Round, in the middle, comes standard in road bearings. In The Box - 2 cups with bearings installed - 2 1mm spacers - 2 0.5mm spacers - 2 dust covers - O-ring - Spacer tube - 10ml All Round Grease - Sticker sheet
$359.00 - $459.00
Shimano cranks fit into BB86 frames when you have this CeramicSpeed Bottom Bracket installed. The kit consists of two cups that are pressed into either side of the central opening. The cups come with CeramicSpeed Bearings installed. There are two versions. The first is our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed Balls. The second version is our coated bearing, which uses those same CeramicSpeed Balls installed on coated, hardened-steel races for longer life and less bearing drag. This CeramicSpeed BB86 Bottom Bracket works with cranks that have 24mm spindles, including both Shimano and FSA. CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That represents an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature the CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed Bearings last at least three times longer than other bearings. Coated Bearings drop friction further and increase lifespan. The coated races see a 50% drag reduction and an improvement in bearing life of 60%. In The Box: - 2 bottom bracket cups with bearings installed - 2 dust covers with integrated spacers installed - Spacer tube - 10ml syringe of All Round Grease - Sticker sheet

The new SRAM DUB crank standard, built on a 28.99mm spindle, allows for a more contamination-resistant BB design while retaining the ultra-efficient & long-lasting qualities CeramicSpeed Bottom Brackets are known for. With an integrated dust cover for all models, the snug & secure fit not only fully protects the face of the bearing, but also delivers exceptional performance without any sacrifices. CeramicSpeed hand-built bearings carry the load from crank to frame with unparalleled durability & efficiency. The SRAM DUB crank spindle requires the bearing contact points to be in a set and designated width, and all CeramicSpeed Bottom Bracket options perfectly match the bearing placement on the crank spindle with the required frame interface for nearly any model of bike. Without the use of unnecessary adapters or spacers, a quiet & stable platform is ensured throughout the life of the product. You have two bearing choices. The first choice is our low drag, long life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The second choice is our Coated Bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag. Compatible with: - Frame: BB86 - Opening diameter: 41mm - Shell width: 86.5mm In the box: - 2 CeramicSpeed Bearings - 2x dust covers - Plast-sheet - 4 x 1mm spacers - 10ml syringe of CeramicSpeed All Round Grease - Sticker Sheet

The PF30 standard is widely used. To make it compatible with Shimano and other 24mm diameter cranks, as well as improve the system, select this bottom bracket. The package comes with two cups and CeramicSpeed Bearings installed. The cups have extended inner sleeves and join with a center section, reducing the likelihood of creaking and increasing the reliability of the system while also eliminating spindle rub on internal cables. The cups mate with 24/22mm crank spindles. There are two bearing options. Both Standard and Coated Bearings feature super smooth CeramicSpeed Balls and hardened-steel races. The CeramicSpeed Coated Bearings have an additional feature: a 3-micron thick metallic layer over the races. This addition makes the races smoother and harder, lowering drag and increasing life. The CeramicSpeed Standard Bearings have only 0.3-0.4 watts of frictional drag per set, an average drag reduction of 75% compared to stock bottom brackets. This is the result of great design, including hardened-steel races and CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. They also last longer. The CeramicSpeed Coated Bearings last even longer and feature even lower drag. Life increases by 60% and drag drops by 50% compared to our CeramicSpeed Standard Bearings. All Round Grease is installed in the bearings. It can be replaced for lower-drag TT and Track Grease or higher-durability LongLife Grease, which adds a bit of drag but stays in the bearing when riding through messy conditions. In The Box - 1 bottom bracket with bearings installed - 2 dust covers - 10ml syringe of All Round Grease - Sticker sheet

The BB86 mountain bike standard was designed to integrate bearings into the bottom bracket for weight reduction. This kit works with the standard: it consists of two cups that are pressed into either side of the shell. There are two versions of this bottom bracket. Both come with CeramicSpeed Bearings installed into cups. The first is our long-life, low-drag Standard Bearing with hardened-steel races and our CeramicSpeed super-round, super hard balls. The second is our Coated bearing, which uses those same CeramicSpeed Balls installed on coated, hardened-steel races for longer life and less bearing drag. This CeramicSpeed BB86 Bottom Bracket meshes with cranks that have 24mm spindles, including both Shimano and FSA. CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That means an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed Bearings last at least three times longer than other bearings. Coated Bearings drop friction further and increase lifespan to applying a coating to the races. The coated races see a 50% drag reduction and an improvement in bearing life of 60%. In The Box - 2 bottom bracket cups with bearings installed - 2 dust covers with integrated spacers installed - Spacer tube - 10ml syringe of LongLife Grease - Sticker sheet
