e13 by the Hive - First Look and Overview
e.13 has recently been purchased by The Hive, a newer company that has a number of brands under it. Brands like Revel, Chub hubs, and now e13. There has been some images of the cranks floating around the internet, however here is the first video explaining the new crank arms, and technologies.

After doing some research and figuring out exactly what's going on, here is a product feature video with Chris Costello on the new e.13 cranks, along with some information on the availability, and technologies that have gone into them.
Details about the new DH crank are as follows:
![photo]()
![photo]()
- Forged and then machined 7050 Aluminum arms.
- 7050 is 40% stronger than most common hollow forged alloys.
![photo]()
- 30mm heat-treated cromoly spindle.
- It is 200%+ stiffer than 24mm steel spindles commonly used in external bearing cranksets.
- German DIN 32711-P3 Polygon interface provides 100% surface contact between spindle and crankarm
- Eliminates fretting corrosion – the prime cause of dreaded crankset creaking and loosening.
![photo]()
- 14mm pedal thread engagement + 7050 arm construction + quality pedal washers.
- Eliminates the need for costly and unreliable pedal thread inserts.
- High quality titanium-nickel hybrid spindle coating.
- Increases durability and extends material life (to just about forever). Tell your machinist friends. They might hug you.
- Standard 104 BCD

Lengths:
- 165mm, 170mm and 175mm lengths.
BB
- Larger BB 6806 (7×30x42)Bearings carry 20% greater static load and dramatically increase BB durability.
- 68/73mm and 83mm BB shell versions.
- New: 24-38 Shift ringset option available.
- For you core freeriders who like to earn your downhill.
- Inner ring bolts to outer ring requiring no inner ring tabs on crank.
Weight: 870g: Crank weight: 759g (165mm x 83mm) / BB weight 111g.
MSRP: $349 w/BB and BB install tool.
Ring Configurations
- e*thirteen guide rings: 32-40T in one tooth increments. Available in black, silver, blue, red, green, and purple. 36-72 grams.
![photo]()
- 24-38 shiftrings: 9 & 10speed compatible. The 24T chainring bolts directly to the 38T chainring to optimize tooth location and provide the greatest amount of modularity and compatibility seen in a heavy duty All Mountain / race weight DH crankset. No grinding of granny tabs and eliminating front shifting options. 138 grams.
- 22-36 shift rings: same as above, slightly lower gearing for our comrades in steeper locales. 130 grams.
Release Date: Global availability by the end of July 2010.

They are non-hollow forged cranks with a non-replacable pedal interface that are heavier than the already insanely durable and stiff Saint, use a model specific bottom bracket (that though the bearing is bigger so is the spindle so likely the balls are the same anyway!)and inner ring.
What am i missing?
I think this is likely the result of a business decision, the Hive dont have brand image in comparison to the big players, so why not merge with E13 pool resources in all aspects and to signify the union create a product = the DH crank is born & ties the two brands together.

e-13 crank weight 870g: Crank weight: 759g (165mm x 83mm) / BB weight 111g
atlas fr crank weight 835g: Crank weight: 715g (165mm x 83mm) / BB weight 120g
saint crank weight 862g: Crank Weight: 762g (170mm x 83mm) / BB weight 100g
Also, the lack of pedal thread isn't an issue because they're using 7050 alloy. Atlas use a slightly higher strength alloy than 7050 (optimAL) in their cranks and I haven't heard of anyone ripping peadal out of those yet. Pedals mostly get ripped out of 6000 series alloy
Pedal inserts? - for sure an issue with Shimano cranks.
Apparently SRAM is holding well...also Race Face with their Atlas cranks is bloody strong even without the inserts...but personally, like the other guys here, I'd rather see the steel inserts on these for a piece of mind.
Exactly. They are DH cranks. AT LEAST they should think about a pedal insert. not saying it`s UBER necessary. Just something nice to have, and losing that damn steel washer is certainly something I hate.
Honestly, the additional weight of 4130 cranks is much worth the strength IMO... but hey, most people are so caught up with weight savings they don't ever think of them as a possibility. Absolute shame also. I saw my buddies raceface arm snap and go in his calf and that was enuf to completely put me off anything close to aluminum cranks. (it's about the same time that I destroyed my profile race arms and upped to profile dj arms).
I wonder why companies aren't using more carbon technology in their aluminum cranks. Forge right over a carbon inner shell with aluminum pedal inserts mounted in the carbon... then forging right over both and machining. Would be a whole lot stronger than threading metal inserts into an aluminum arm. No reason you couldn't pre coat the carbon in high temp epoxy to handle the forge process.
Hmmm maybe something we will see in the future?
- It is 200%+ stiffer than 24mm steel spindles commonly used in external bearing cranksets.
So in other terms, a hollowtech type arm will be many times stronger than a solid arm (machined with i beam or whtever other way to strengthen and stiffen that they can think of.
Reason why you don't see those 2,000 foot tv towers using i beams. They use tubing all the way up, with i beam reinforcements. Tubing is better against flex, and more evenly distributes load, wear, and fatigue.
just to let you guys know, profile dj arms are disappearing from the market

heehee. For those of you anti breaking products, check em out. How much do they weight... well, less than your frame and more than your balls. lol
Now crank arm works as a cantilever beam, both for bending and for twisting, as the length of the pedal adds a leverage. While doing these G-outed burms it also works for stretching, but well in case of this material it plays absolutely no role comparing to previously mentioned forces. If we talk buildings, you find tubes quite rarely for beams both in steel, wood or concrete, doesn't matter. T and C sections are most common. An that's what that crank arm is about
