My XT Hollowtech II BB needs replacing, and I notice that the new ones have smaller bearings, and therefore require an adapter to fit the existing BB tool. Shimano claim that they have better sealing than the older style, and weigh less.
I thought that the larger bearing of the old design would help improve bearing life? Am I wrong? And are the new MT800 any more resilient than it’s predecessor?
If they are still a bit cheesey, what do people use? Hope is too expensive for me. I have seen people mention Gusset and Token, but those posts are a few years old now and they are out of stock on some sites. Is there anything better for similar money?
Thanks
