You think that your bike’s performance features could be enhanced with components selected á la carte at your local bike shop — and that you should be able to accomplish this despite the spawn of deviant bottom bracket “standards” that have created component compatibility issues. Conventional threaded bottom brackets like your English-threaded BB shell shouldn’t foil plans to upgrade your ride. ROTOR conceived its Universal Bottom Bracket (UBB) concept to eliminate the complicated bottom bracket/crank compatibility challenge that has increasingly frustrated the mechanics at your LBS. The BSA 30 is the “yes” component to “Is this compatible with my English-threaded BB shell for a 30mm axle?” Versions: BSA30 68-73mm ceramic red – 96g BSA30 68-73mm steel black – 89g Characteristics: – Designed to work with BSA threaded bottom brackets and 30mm axle ROTOR cranksets – aluminum alloy 7075 100% CNC-machined – Silicone seals Color: No BB Size: No Technologies: No Compatibility: BSA68mm, BSA73mm Crank Axle Compatibility: No Discipline: MTB Additional Information - Weight: 0.170kg -Dimensions: 10x5.5x6cm -Type: Steel (Black),Ceramic(Red) Please visit our website at http://www.ecomtb.com.my OR https://shopee.com.my/eco_mtb ** There is 1-3cm errors due to manual measurement.
