Saris H3 Discussion/Issues

A lot to ask, but next time you have it apart again could you measure the filed down top hat please. I have a brand new H3 & think this may also be part my issue.

Thanks for all the above input, in my case I’ve now found the main culprit & unfortunately its the Avio power meter. The “one time calibration” after fitting, which involves hanging a 10KG weight from the crank is actually not one time at all. In the year since then, its gone from 10KG = 98NM to 125NM !
Not sure when or how this happened but I’ve now got to recalibrate my brain with dropping from 314w FTP to 245w & years worth of useless power data, very disappointing to say the least.

I guess on the plus I’ve still trained & will hopefully see the benefit ?
Anyone want an expensive 105 crank arm :roll_eyes:
