Even that UK vendor's chart posted above said the benefit was .2 watts. First, being a vendor claim makes it suspect and second, .2 watts is nothing, and third, if you want to pay $350 for a bottom bracket then you drank the coolaid.
I packed my Super Record Cult bearings with grease because there's no reason not to, they will be better protected, and I didn't want to have to oil my bottom bracket every three months.
^ I do read numerous articles saying free-spinning cranks are no indicator of reduced watts but just thought it's a given for ceramic BBs. I didn't get it for the watt savings actually (actually it's for weight savings ha) so that doesn't matter. Didn't install it myself anyway.
Well
My Canyon Ultimate CF SLX is equipped with a Shimano BB92-41B Pressfitt 86,5 Road bottom bracket. The plastic cups of this press fit bottom bracket started to release from the frame, providing 1 or 2 mm. between the cup edge and the frame. James Huang BikeRadar article “I’ve had it with press-fit bottom brackets” in which he covers tolerances, used materials and silencing creaky noises, came with two applicable take-aways:
1. Ditch the plastic cups;
2. Minimize the adapters;
I went for C-Bear because of the aluminium cups, the value for money, customer-driven company with good vision. C-Bear has a long term sponsorship with Lotto Soudal, Wanty Group Gobert so if a C-Bear can withstand the punishment of Andre Greipel, than it's certainly good enough for me.
