Iso square CrMo axle with alloy forged cups and carbon body and sealed bearings Patented CNC ISO Square BB/Campagnolo Compatible.
The bottom bracket is a key component of every chainset. Smoothness movement is critical, yet must be balanced by enough sealing technology to sustain a reasonable lifetime of use. FSA MegaExo bottom brackets are the result of years of development and feature exclusive innovations to guarantee the best balance of efficiency and durability. FSA uses the state-of-the-art materials like Silicon Nitride formed ceramic ball bearings, or highly polished chrome steel ball bearings, depending on the level of the bottom bracket.
MegaExo and 24Ømm spindle cranks to press fit BB86 frame.
Ceramic bearings for improved performance and longevity.
Rather than relying on the pressfit shell for alignment, the UBB4630's threaded sleeve locks both cups in place, increasing BB shell stiffness. This also ensures a smooth, uniform spin free from creaks that often plague pressfit while preventing bearing overload. The perfect alignment also means longer bearing life while the sleeve also prevents cable guides rubbing against rotating parts. "The motive for the UBB4630 was to address challenges related to bottom bracket installation and durability with specific frames," said David Martinez, head of engineering at Rotor.
Ceramic Bottom Bracket compatible with 30mm axle chainsets.
The cups permit extensive adjustment of the chainline and feature a sealed bearing construction which provides durability and long lasting smoothness.
This product from Token offers a great upgrade alternative over its main stream competitors for BB30 and BB386 frames.
Suitable for both road cycling and mountain bike (MTB) riding disciplines, this versatile bottom bracket (MTB) provides excellent strength and reliability wherever your next ride takes you. Thanks to its forged CrMo steel spindle, it provides a durable interface between your JIS square tapered cranks for maximum toughness. Another highlight is its industrial 6002KRS cartridge sealed bearings with oversized 3/16 balls, which offer dependable protection against water and dirt alongside its double seals. FSA has a long history in the sport of cycling and a strong heritage of innovation in design and manufacturing. The brand produces world class bicycle components for road cycling, MTB, and triathlon for World Tour teams, club riders and people who just love to ride their bikes.
Manufactured to create a precise and functional interface between your frames bottom bracket shell and your 24mm cranks, our ThreadFit™ 24 bottom brackets ensure that your cranks will spin lightly and without interference. To help with bike fit issues we have developed a range of conversion kits that allow our ThreadFit™ 24 to be used with a wide selection of road and mountain bike cranks. As with all Chris King components in our ThreadFit™ 24 bottom brackets it all starts with the bearings. We make our bearings in-house and our process allows us to place more balls per bearing than our competitors. More rolling elements per bearing translates to a stronger overall bearing system. A bottom bracket-specific upgrade to our legendary sealing system allows the bearings to be purged and re-greased using our precision made injector tool. This combination of strength and serviceability gives us the confidence to offer an industry-leading 5-year warranty on our bottom brackets.
