Maybe LX or XT level??

anyone know?

Can you post a pic? There are a handful of cranks out there that use the Octalink spline.

Well the chainrings suck, thats for sure. As far as the arms, they aren't that bad for XC/trail.

The tech behind it has been eclipsed by 2 piece outboard cranks, which are so much stiffer with a larger bearing.

Um, Sugino cranks? I thought Specialized made the Strongarm cranks in house.

They definitely aren't Shimano.

Spec. has never made a crank in house to my knowledge, they shop in Taiwanese parts distributer catalogs and slap a logo on 'em.

I've seen Spec. branded FSA and Sugino cranks.

My StrongArm 1's had Sugino clearly stamped on the back of the arm.
Don't know about the SA2s.

Hmm... Mark, the more I look at those, the more they look like LX/XT cranks... They must have changed their crank supplier, since the old SAII's that I've seen several sets of weren't like those. The self extracting crank bolts aren't the same, though, and that seems like an odd detail to change.

:think:

btw, it would be more helpful if you took a picture of the other side of the crankarm, where it actually mounts to the bb

They're Octalink... I already looked it up.

btw, i don't think crankarms are anything that special. you don't want ones that break and that are very light. xtr would be bad for fr and hussefelts for xc.

also weightweenies have Stongarms at 506g, 03 XT at about 450

What about the new carbon road cranks? Those are completely in house.

And what you said above about outboard bearings, can you really prove that the bearings themselves are stiffer, or just the crank arm design is stiffer, which happened to be released at the exact same time? The stiffness coming from the bb spindle and bearings is going to be pretty unnoticeable compared to the stiffness of the crank arm. I.E. when you switch from a steel to a ti spindle, can you notice the difference, honestly?

IIRC, the XT and LX crank arms were exactly the same, but the chainrings that came with the XT cranks were lighter.

I don't buy that the huge jump in sizes for that big hollow spindle for outboard cranks doesn't give you a big increase in stiffness.

I haven't ridden any of the outboard bearing cranks, but given how much torque is on that spindle, it should provide a noticable increase in stiffness.

Don't know about the new carbon cranks.

As for the other part. Can I prove it? No, not an engineer:D The bearings are larger and sit further away (compared to ISIS/octalink) with a larger spindle. They "feel" stiffer. Hop on a bike with octalink XT cranks, then on one with the new 2 piece and you should notice a difference. I do at least.

Does the crank have an big ole indent on the inside? You wouldn't see that on the Shimano offerings

pretty sure my XT cranks looked like these on the inside.

I'm 85% sure that mine are smooth on the inside. Don't forget the XTs are 'hollow' and I suspect that those are not.

I'll give you a definitive answer after I get home...

Yup... that's my old roommates stuff - working on the shipping right now (bunch of stuff finished at the same time).

Shimano doesn't make private-labeled stuff for people. Spesh and Trek (Icon) Cannondale (Coda) used to be big into that stuff. There was a big push a couple of years ago to have bikes with bike-company branded bars/stems/posts/cranks. Saved the company TONS of money, because they didn't have to pay more for a similar product with a brand name on it, but also didn't have some no-name stuff on there.
Not saying they're not nice cranks, look great. Careful though, some of those cranks tended to have slightly softer aluminum which made them really easy to round out a little if ridden loose. The older XTs were notorious for that.

Shimano doesn't relabel. They only sell their branded stuff through authorized dealers only. They due however license their proprietary deisgns and interfaces to other manufacturers.
