BB1 ITA
You've decided that your bike's performance features could be enhanced with components selected á la carte — and that you should be able to accomplish this despite the spawn of deviant bottom bracket "standards" that have created component compatibility issues at your local bike shop. Conventional threaded bottom brackets like your Italian-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 BB1 ITA is the "yes" component to "Is this compatible with my Italian-threaded BB shell with a 24mm axle?"

Η μεσαία τριβή PF4630 είναι για πλαίσιο PF30, BBright ή 386EVO στο οποίο θέλετε να εγκαταστήσετε άξονα BB30. Έχει εσωτερική διάμετρο 46 mm και λείο εσωτερικό, αν και τα πλάτη ποικίλλουν από 68 mm έως 86 mm. Ο άξονας έχει διάμετρο 30 mm.
Αυτή η μεσαία τριβή έχει σχεδόν μηδενική απώλεια ισχύος λόγω τριβής, χάρη στα ρουλεμάν. Τα ρουλεμάν έχουν εξαιρετικά λεία σφαιρίδια CeramicSpeed που κυλίονται σε ράγες από σκληρυμένο χάλυβα.
Οι μεσαίες τριβές ΒΒ86 είναι συμβατές με τους άξονες Shimano. Το κιτ αποτελείται από δύο κύπελλα που πιέζονται σε κάθε πλευρά του κεντρικού ανοίγματος.
Τα κύπελλα διαθέτουν ρουλεμάν CeramicSpeed. Οι μεσαίες τριβές προσφέρουν χαμηλή οπισθέλκουσα, μεγάλη διάρκειας ζωής, σκληρυμένο χάλυβα και τα εξαιρετικά λεία σφαιρίδια των ρουλεμάν CeramicSpeed για μέγιστη απόδοση.
