Re Shutter Precision, what is the experience with how long (kms) the bearings last as they (and Son's) are said to be only factory replaceable?
I ask in that 6 years ago I was having an audax bike/wheels made and had the option of SP or Son dynamo hub, the SP distributor said the warranty was only 12000kms but they had a factory bearing replacement program for a reasonable amount except that meant getting the hub out of the wheel, posting it off and then getting wheel rebuilt when the hub was returned, all a bit of a fluff if I was doing 10-12,000kms per year (ie potential replacement each year?)
Son bearing warranty was 50,000 kms, much more to my liking but twice the price.
So I went with Son and as it turns out I am approaching the 50000 later this year, all looking good so far but I will want everything rebuilt leading up to 2023, the Son might last 100000 or ?? but I am thinking options, probably just get the Son factory bearing replacement and I have a backup Shimano dynamo hub in a compatible wheel on my tourer I can just swap while the Son is on holiday in Germany.
PS My Shimano dynamo hub originally lasted about a week, horrible noise on my third ride and blackness, replaced by the touring bike dealer and has now lasted 8 years, only a fraction of the audax bike kms in recent years although the tourer was my audax bike too before the new one born, did my first 20x200 brevets on it. Thanks
