I suppose Extremely-Torque doesn’t glance so dangerous now, does it?
[“In faccia, Shimano!“]
However the issue isn’t the entire Hollowtech II backside association; it’s the truth that some years again Shimano began bonding their high-end cranks in combination for some reason why. The outcome? Carnage!
Wait. Is {that a} measly six folks injured out of a whopping 760,000 cranks bought? Or do they only imply that once the crank fails you’ll enjoy six thrilling forms of damage? Both approach, I had no thought I used to be flirting with crisis right through the time I used to be driving a motorbike with a contemporary Dura-Ace crank:
