Carbon Cranks On The Shore?

What is your experience with carbon cranks on the shore? How are they holding up and what brand models are breaking?

I had SRAM X01 Carbon cranks for 3 years. They were pretty ugly by the end, with scuffs and a bit of the arms’ sections worn down from rub against my foot. But they held strong over that time and I ended up selling them with a bike.

That said, I now have alloy cranks and don’t notice a difference in performance.

I'm a park rat in Whistler who's ran carbon cranks for the last four or five years there, with tons of mileage.  I've broken an X01-DH, but only after I replaced an older X01-DH because I was scared it'd break because I used it so much.  Then I broke two e13's in rapid succession.  This year, a SixC held up all year.  I went to alloy a few times in there when the others were down, and if I were honest, I couldn't see a difference.

That said, if you ride a lot, the wear on the arm your front foot uses is going to be punished.  Keep it super-taped.  Callum at ride wrap has a new, super-thick 3M piece that is now mandatory for me.

I've gone through two Next SLs and one SixC crank, always the pedal inserts.  Fortunately RF has warrantied each time.  I'll probably try Shimano XTRs next time.

Do you run flat pedals? I’m thinking wider flat pedals are a longer lever and perhaps are more prone to ripping out of pedals threads or ripping the insert out. I have cracked an XX1 crank but it was a tiny crack. The creaking was unbearable though and it was warranted.

Broke 2 sets of Next SL's (pedal insert) within about 3 months of riding each set. RF warrantied them but sold my last set to try something new. Tried the new E13 TRSr cranks and they have been going strong all year on the Shore, Squamish, Pemby and a few Whistler park days. So far so good. My buddy rides Hope and likes those as well...

Carbon cranks and bars are 2 components on my bikes that I only now trust to aluminum....

Alloy is only marginally heavier given how much tougher they are at half the price. Turbines are very tough and Atlas even tougher. Put those little boots on then smash away.

RF Turbines... strong, light and not that pricey.

If you stick with alloy XT's are hard to beat. $99 on Jenson right now and weigh basically the same as Turbine that are $70 more. Get a nice OneUp ring and call it done...

Get the XT ring. It’s steel with a carbon reinforcement. Longer lasting.

100g more than say an XT is "way too heavy"?
