Rotor 3024 bottom bracket bearing with industrial bearings and non-contact labyrinth seal for road. This ensures optimum protection against dust, water and dirt, while at the same time ensuring the smoothest possible operation. Compatible with all Rotor, SRAM and other cranks with 24 mm axles. For road frames with the standard BB30, a housing width of 68 mm and inner diameter of 42 mm.
BB30 to BB24 converter. which allows the installation of conventional BB24 cranksets in BB30 frames
New plastic caps provide significantly improved lateral compression and resistance to deformation, enabling crisp shifting
Broke BB30 chainset in my synapse and wanted to replace with Shimano to match rest of groupset. Internal cable routing around bottom of frame meant other converters wouldn't work (Praxis/Threaded insert for Hollowtech/etc). I took a punt on this due ot he narrower mid-section, it fits like a glove, easy to install and seem to work really well. Just be careful not to knock out the bearing cap when pushing the chainset spindle through the centre hole. I did and broke it, Bikester kindly sent a replacement. In summary: Highly recommend.
