Vet ikke om dette hjelper, men det står spesifikt på slutten at ting er kompatible.......hele greia om kranker her :http://www.bikeradar.com/gear/article/complete-guide-to-bottom-brackets-36660/
Hvis du kommer frem til at det passer og ønsker bedre greier så er jo

The Specialized OSBB system
"The 30mm bearing is a good choice when using thinwall aluminum spindles," he said, "and the narrow bearing stance (relative to outboard bearings) works perfectly with our carbon arm design needing to make the turn into the spindle. The OSBB is basically the same as BB30 but with a little tighter tolerances and a 0.5mm difference in the clip-to-clip dimension. Cranks of both systems are compatible with each other."
Sånn som jeg forstår det så er radial vs angular uavhengig av om ting passer eller ei, det ser for meg ut til å handle mer om hva som funker best mtp slitasje....tatt fra omtalen av det dyreste PF 30 lageret deres (XD-15)
Angular contact bearings are a step forward in outboard bottom bracket design. Why? Deep groove radial ball bearing cartridges are not designed to be "adjusted." Any inward or outward pressure on the inner races put them out of alignment with the outer races, forcing the balls to ride up the side of the groove and exerting greater pressure on the races. This results in increased friction and premature wear. Since almost all outboad cranksets exert some inward pressure on the bearings when installed, it only makes sense to use a bearing designed specifically for such loads. Likewise, the BB30 wave washer keeps pressure on the inner races of the bearings, making the angular contact design of the XD-15 ideal.
