Pretty sure JM has some carbon cranks on sale cheap.All about the... cranks for weight..
ouch! what did you hit, tire and pressure do you run?That's how my LB rim ended up a few days ago

This one is just 50g lighter than the ex471 that will replace it.
That's a 100g or 0.22lbs difference for a pair of wheelz... what rims did you had to loose so much weight?
Mine were 1st gen LB "trail" rims. I was not kind to them. Replaced with 2nd (or 3rd?) gen LB all-mountain rim. No issues with that one... yet.knocking wood
I've been beating on these for two seasons now and they're perfect. enduro rim, extra layup on the rear, dt comps and real tires.
I hope they don't explodify like both of yours have.
823 are definitely on the heavy side of things!ouch! what did you hit, tire and pressure do you run?
I went from 823s to their 30mm 'endurbro' rim. I'm going by posted weights so take it as a +/- amount. Regardless it was very noticeable.
Tell me more.As for anything build with carbon fibers, it is very strong when new and slowly loose strength mostly locally every time you bash it a little hard until you reach the point where it breaks once you hit it hard enough on a weak enough point.
Ahh, so you just made that part up then.When you buy me a beer
ok materials nerds ... educate me.As for anything build with carbon fibers, it is very strong when new and slowly loose strength mostly locally every time you bash it a little hard until you reach the point where it breaks once you hit it hard enough on a weak enough point.
Yes - if you ride at midnight.knowing that there are tons of variables, is it accurate to generalize that within a certain window or movement/compression/etc carbon can be built up to have an infinite fatigue life?
Here's the long and short. You could build a carbon bar that will not fatigue (or have essentially infinite cycles until failure) under normal mtb loads but it will not be light so then what's the point of Carbon? It's not about the movement but about the force applied and the resulting yield/flex. If you make it stronger it won't flex at lower forces but then it will be heavy cause you needed a bunch of material to make it that strong. You could do the same with aluminum.knowing that there are tons of variables, is it accurate to generalize that within a certain window or movement/compression/etc carbon can be built up to have an infinite fatigue life? and only be at risk of deforming/degrading/breaking if pushed beyond that window?
But only on cloudy or moonless nights.Yes - if you ride at midnight.
Yo!! Stop getting hurt. You gotta show me the goods at Briones this winter.Thankfully I just fucked up my back so I couldn't ride it if I had it anyways...I guess that's better?
