Very clear and insightful videos. Keep them coming. I have been riding a carbon Truvativ Stylo crank for a couple of years. No problems and much cheaper than XX1 without much of a weight penalty
nice. I like the self pulling system a lot more than Shimano cranks, but other than that...well Shimano cranks are cheap and they just work. If you get a deore you can't change the ring, but that price is just great.
And also, not only are Shimano alu cranks strike-proof, they also use 24mm steel spindles that are of a material arguably better suited to the kinds of loads they experience, and allow for larger, much more resilient bearing ball size (especially in very popular BB92 and similar pressfit systems).
The 3 bolts don't really need locktite. They are not load bearing bolts just to hold it on. And the spacer ring would stop them from backing out anyways.
I have never considered carbon cranks to be honest and this video didn't convince me as well. BUt anyway, as a usually very good review and interesting to watch. Thank you!
Wait...hold up. Shimano SLX crankset with the oval chainring is only 15 heavier than Sram carbon? I would bet a mortgage payment it would be at least 100g. I'd probably go with Shimano + AB oval if that's the case.
The X1's came on my V4 nomad that I got over a couple years ago and theyve survived everything I've thrown at them! Only one of them required a helicoil at one point
I love my X01 carbon crank, but holy crap is that 8mm crank arm bolt a nightmare to remove. I have always used Park grease on the bolt and spindle threads, but I still always need a 3 foot cheater bar to break it loose.... and it sounds like it literally breaks too when it finally lets go. 3 days ago I swapped out my chainring and used some Park Anti-Seize compound for the first time and hope that helps in the future.... man that bolt gets frozen on there!. That can't be by design??
Update: The Park Anti-Seize compound made a world of difference but it was still tight. I spoke to SRAM and they said the issue was on the 'older' crank bolts where the design of the aluminum bolt's threads would gall with the aluminum spindle's threads. SRAM changed the aluminum bolt design on the newer cranks and it's supposed to eliminate the issue. You can also buy their steel bolt which eliminates galling and uses a 10mm outer cover instead of the standard 4 pin cover ( SRAM part number 11.6118.066.000 ). Be aware that 4 pin cover is a total beotch to remove though (left hand threads and tight as hell for any pin spanner wrench ) but Abby tools makes a great tool for it and makes it a cinch to remove www.abbeybiketools.com/products/dub-crank-dust-cap-tool I Love SRAM DUB cranks and bought the Abby tool and will keep a generous supply of anti-seize on hand.
Been soaking 8mm driveside bolts in TriFlow Oil the night/day before removal. * There are 4 small holes that allow oil or grim into the 8mm bolt area. * Seems to free up the 8mm bolt substantially.
LBS ordered 3 sets of SRAM XX1 carbon cranks and all 3 had loose debris rattling inside the hollow crank arms. Im wondering if this is a known issue and it’s just a manufacturing defect that won’t affect safety or performance. I mean I can warranty them but I’m 3 for 3 with such issues so I don’t know if SRAM has a set that doesn’t have this problem.
@@LoveMTB people are reporting their hollowtech-ii cranks getting stripped. Specially the deore 12 speed ones. Do you know if it's the metallurgy? Or an installation problem? (not tightening equally and using a torque wrench as Gud-N-tite will weaken the threads and the clamping force). People reported on MTBR forums along with our local Facebook groups as well with their Shimano Hollowtech-II cranks flying off (non drive side) - even on new bikes.
@@LoveMTB not nagging , I am old and out shape. So 15g not a big deal 4 me right now. I just like the looks of it, is nice to have some cheap good quality CF available. Glad SRAM is doing it. Thanks for the videos

I have the XO1 cranks and sram Force carbon, and for what I can tell is that sram cranks (arms) are all the same. I think that even sram XO (10spd) are the same, at leas mine XO1 look like the XO.
Im running Raceface turbine cranks on both my bikes. I wonder how they compare in weight to those cranks. Oh also the Sram cranks you got have 30mm spindle? Shimano is 24mm.
