Not sure if you managed to find any but here is my experience. 20 mins of riding from brand new, 2019 s-works. First minor pedal strike.Hi I’m looking at purchasing a set of carbon cranks from Praxis for my 2018 Expert Levo, does anyone know the stock crank length 170mm or 165mm? Or has anyone tried these cranks yet?
Thanks
Thank you so much and sorry that happened hopefully they give you your money back.Not sure if you managed to find any but here is my experience. 20 mins of riding from brand new, 2019 s-works. First minor pedal strike. View attachment 14670 View attachment 14671 View attachment 14672
Sadly no, Praxis stated no manufacturing fault. Personally, if that is the case, I cannot see how they can be fit for purpose. I have replaced them with alloy and will not put carbon cranks back on. Pretty poor for a $15,000 bike.Thank you so much and sorry that happened hopefully they give you your money back.

Another set?
i dont see the logic behind putting cf cranks on a 45 lb bike w a motor. aside from bling factor
whats the difference in grams like 50 grams total? you can shed more weight by taking a piss.
They are totally cool and every gram you save extends your range and cool factor. I was about to buy them but this has stopped me totally in my tracks. When they break they also look very sharp wouldn’t want to get speared by carbon shards in a big off.
None for the reasons I stated but 30+ years windsurfing where I have seen both success and dismal failure of carbon components.I have hitted SW carbon cranks to rocks very hard several times. No problems so far. I don't know how much experience Mikerb have carbon mtb frames and parts. I've had zero issues with carbon frames, cranks, seatposts, handlebars or rims since 2013. So I think carbon is fine. However, looks that Praxis cranks could be the first exception.

Composite lay up will always be stronger followed by inpreg.You can make carbon composite more impact resistant by using a biax weave with kevlar but that is hard to lay up other than as a flat surface so usually added to a composite in small vulnerable sections. Strange with the broken crank pics There was no obvious laminate layers almost as if they were moulded using epoxy with micro fibres rather than a composite lay up.
