 I think everyone knows by now that every major "standard" is nothing more than a trojan horse for some Company's own "standard. sram UDH for example. My theory is why the crankarms are getting shorter is because druvetrain ranges are getting bigger to compensate. wont be surprised if a 13 speed is coming out soon

 @mchenrya: what is wrong with 175? Always used those, never had any issues?
  • 8 5
 @saladdodger: Unless you're over 6'2" you'll be more comfortable and make better power on shorter. Regardless of height, shorter cranks feel nicer jumping, spin smoother over rough ground, and have more clearance.

flag capoeirabg (Mar 29, 2023 at 23:44) (Below Threshold)
 @lelandjt: Cranks length is also defining your feet' position when not pedaling so the short crank length limits your stability because you are stepping at a smaller distance, this gives you less leverage over your bike control from the feet. So not everything is just pedaling
  • 18 2
 @capoeirabg: yeah, I don't know how those poor MX riders do with having both footpegs inline, them riding as hard as they do must be some sort of magic considering how little stability their pegs are giving ... Or you can consider that lunging while going down is just making it harder both physically and technically. Try to move up and down in a lunge position and in both feet parallel, usually called a squat position, in which do you get more range or movement, and strength ? Yeah ...

 been riding 170/175 mm my entire life. 6 foot , 32 inseam. When I see so many of these 160 necesities down here I'm wondering if biking is happening only in Hobbiton and some small other areas.

 @mininhi: The resurgence of short cranks started with ebikes, where you have to imitate a pedaling motion to engage the throttle, no need for long levers there. And then people liked the elevated clearance.
  • 1 3
 @saladdodger: people are on a trend now where they enjoy pedaling at twice the normal speed and and enjoy not having the power/ torque you can put down with longer cranks. People think having 15mm shorter cranks are gonna magically stop pedal strikes but from what Ive seen its just a myth!! When I go through rough shit i usually have my crank parallel to the ground but apparantly most poeple ride one pedal down now lol.
  • 2 0
 @mhoshal: Actually, I want 160s because my calculated ideal crank length is right around there based on 5'8" height and a 28" inseam. Having proportionally sized cranks should make me more torque/power and be more efficient.

In combustion engine terms, having 170 cranks on legs this short is akin to having a long stroke but short connecting rods that can't take advantage of it.

It's something the roadies have actually invested a lot of research into.

 @edthesled: true, but: I didn't torque a ZEE crank properly and when landing a 2m drop both sides were parallel. It feels a bit weird to ride with both pedals down, i can tell you. After some love with a hammer and a large screwdriver i got it off and after some cleaning it went back on and was bombproof for some more years and big impacts. That's a good MTB product.

 @edthesled: i was referring to how the design when used properly basically has nothing to work itself loose, raceface's interface on atlas cranks i have reminds me of square taper shitshow. one ride with the crank screw loose while it's not that easy to notice it's loose and you can toss it into trash while it wouldn't happen with hollowtech II interface, you'd really have to be an ass to ride it while you know it's loose to ruin it.

 @zyoungson: I tend to agree. I don't love the way that carbon fails (abruptly and completely), so I avoid it for my cranks and handlebars. The benefits (few grams, some degree of "compliance") don't outweigh the potential costs (complete failure, more $$).

 @KJP1230: everything fails at the worst(highest load) possible time. lol. its like when people say, "my keys were in the last place I looked!" yeah, I f*cking hope so.....cuz if you kept looking after you found them....Big Grin
  • 3 1
 @KJP1230: your understanding of Modern carbon fiber failure is a bit behind the times. from a guy that has broken more bike parts, frames, wheels, bars, etc than I care to admit......Carbon doesn't fail any more spectacularly than AL does really. I have cracked carbon wheels and finished races with multiple more stages to go, and I have dinged AL wheels that would no longer hold a tire on the bead....day over!

so there are anicdotal examples of failure to confirm your opinion anywhere you want to look. I will say though, I break a lot less wheels, cranks and bars now that they are all carbon from a reputable brand(just say no to Race face and E13).
  • 2 1
 @Mtbdialed: Notice, I did not say that I am personally opposed to carbon rims, frames, etc. Rather, I am concerned about crank arms and handlebars in particular. Because the rim itself is formed in a circle, when it cracks, it will likely stay round in shape. I also know of folks who have cracked rims and managed to finish their ride or otherwise limp down the mountain.

On the other hand, when a carbon crank arm or handlebar fails it may break clean or sheer. Because this is where my body and limbs attach to the bike itself, I prefer to avoid carbon on those particular parts.

I believe there was a case reported on this very site of a broken carbon handlebar under a semi-pro rider just last year - my understanding is fully modern.

 @KJP1230: you are discounting bars and cranks being made of AL and also failing in similar manners. would like to see my photo gallery of AL bars sheared in half? lol

I'd love to see a personal photo gallery of one, much less multiple, AL bars that sheered.

 @Mtbdialed: aluminum does not fail as often as carbon does. Aluminum parts are much more popular because they're better. They do not fail in a similar manner to carbon, the materials are way to different for that to be the case, and you have no evidence of this.

I'm sorry you wasted so much money on bad parts

 Why is the back side not shown at all?

Extensively CNC machined, but they couldn't be bothered to use a radius tool...

Heavier, probably flexier, much more expensive than slx. Why would you bother?
  • 3 0
 The website shows the backside. There's some careful language here about almost every 'visible' surface being machines. So, the backside isn't machined (not does it need to be). These are forged aluminium cranks, with CNC finishing on the front face. That in itself isn't a bad thing (forged will be better than billet or cast). They would want to add some sort of advantage in stiffness over SLX to bother though, and it's not like too many people are complaining of flexxy SLX cranks.

 I had a set of expensive carbon E13 cranks, they failed because of a defect and customer service refused to even look at them for warranty, despite a report from the LBS.

 SRAMTM and ShimanoTM 12-Speed compatible narrow/wide -> what is the warranty process if there is damage to the shimano / sram chainring which might be caused by the E13 crank or vice versa? I have experience being rejected by shimano / sram and also E13, so in my opinion it's better if you sell it in the form of a complete chainwheel instead of a separate crank / chanring only

 Yes, after the crater a flying rock just created on my LG1 crank, by the axle at the opposite end of the left crank, I'd say carbon cranks can be a scary thing to live with because you don't know how those large chips will affect the strength. The location I mentioned is the most exposed one as most people ride with the right foot forwards. Something similar to a downtube protector is a must there.

 @wyorider: there are a lot of hollow cranks out there so it’s not exactly bringing something new anymore. If I’m not mistaken SLX cranks are similar in weight to these so it’s not like it’s doing any good there. Cane creek cranks arguably are sweet because weight and durability, but at what cost? There are $500 cranks that are in the same weight range. These are pushing for that aesthetic driven market. If the cranks look decent, which they do, and the weight is reasonable, which it is, then it’s a decent offering in the subcategory of bling cranks.

 @wburnes: extra strength doesn’t matter if something is already strong enough. 7075 is 3x the cost of 6061. If you were to have a component that works in 6061, all using 7075 would achieve is a higher price for no reason. If you make use of the fact that yield strength of 7075 is 1.82 times higher than that of 6061 and gain significant weight savings that cost is justified.

Cross section and spindle-to-arm interface are probably more important that the alloy.

 @rpl3000: these are forged! 6066 is somewhere in the region of 25% stronger than 6061; it's pretty handy stuff, though not at the same level as 7075. Not sure how it performs with forging compared with others.
