Hello. On my Cannonadale Supersix Evo SE II model 2022 bike, I want to replace the BB30 bottom bracket with one where I can use cranks with Shimano GRX chainrings with an axle diameter of 24 mm. The diameter of the hole in my frame is 42 mm and the distance between the bearings inside is 67 - 68 mm and the distance outside is 79 - 80 mm. Will this bottom bracket fit there? Thank you for your answer.

Dobry den,
zial nie, Cannondale Supersix EVO vyuziva pre Cannondale typicky asymetricky Ai stred, potrebne je tak pouzit aj Ai stred. Zial vhodny stred pre 24mm Hollowtech II kluky dostupny nie je u ziadneho z vyrobcov.
Dostupny je momentalne len standard DUB pre kluky s 28.99mm oskou - https://www.mtbiker.sk/shop/komponenty/stredove-zlozenia/press-fit/sram-dub-pressfit-30-cannondale-ai-stredove-zlozenie-cestne-83mm-.html.
Hello. Is this bottom bracket suitable for carbon frames? If I understand correctly, you don't need a press, but the pressing is done by tightening the threads? Which wrench is used? Hollowtech 2?

Dobry den prajem,
ano, stredove zlozenie sa umiestnuje bez lisovacky priamo do BB30 ramov pomocou akychkolvek standardnych 16-drazkovych 44 mm klucov. Pouzitie v karbonovych ramov vyrabco akokolvek blizsie nespecifikuje/nezakazuje.
I have Shimano Ultegra cranks on my bike, which is a 24mm axle (if I'm not mistaken) and the bottom bracket (cups) have the inscription BB30. Will this crank fit me?

All the answers to questions about delivery, payment, security, returns, warranty and much else.

Amazingly accurate and of outstanding quality. Cannondale Habit 2016 was used. I highly recommend the brand to everyone. I was not disappointed with the quality.
