Sugino 75 Sealed bottom bracket (CBB-SG75)
 

Hello.

I've learned so much from everyone's knowledge - thanks for your expertise!

The Sugino sealed bottom bracket (CBB-SG75) has only been on the market for a couple of years (introduced in 2016). Does anyone have experience using it? I'm wondering if it's in the performance realm of Phil Wood or similar. I understand its specialty is to be used with Sugino 75 cranks, but would like to know if its an above-average bottom bracket and if people recommend it. Unfort I can't find any real-world experience / reviews.

Thanks in advance,
Matt

Having myself learned after the fact...

Note that Sugino 75 cranks and bottom bracket spindle have a proprietary taper. It's close, but not quite ISO.

Answer from Yuki from Sugino corp. 75 are not ISO.

I have that bottom bracket, on sugino 75s. I upgraded to it over the summer. It flies compared to my old bb. But the old one was old and not great to begin with, and eventually wore out. So maybe that is why I notice a difference. Hopefully it lasts longer than the old one!
