I’ve been fortunate enough to be giving these little guys a tour of the trails up here on the sunshine coast in an attempt to find out how long they last.
These are of course some external ceramic bb bearings that Duncan from DIYMTB has kindly forwarded on to me to ‘thrash test’. To speed up the process, I thought it might be worthwhile to throw them in the deep-end, so to speak, & run them without the external cup seals as well. So I did.
Out in the rain, sand, mud, dust, & some more sand. After months & months of this, & including the wintery (yes qld has a winter!) conditions prior to the 24 hour worlds, I am just now onto my 2nd set. I can safely say that the ceramic option not only free’s up the cranks in terms of resistance but I’d have a stab at saying the off-road longevity of these compared to a standard set is improved by roughly 3 times. And that’s with pure neglect & running them without the seals. A figure confirmed by some bike shops around the area as well. Nothing like a click free bottom bracket for months with the added bonus of increased rotational freedom.
I’ve just received a set of ceramic bearings for my pedals too. I dare say I won’t need to be getting new ones of these for quite some time. Thanks Duncan.
