    Fifteen G cranks??

    Does any one have any information on these cranks other than the post in bike mag and on the hives site. http://bythehive.com/?page_id=610/ They are looking to be a promising crank with BB30, 104/64bcd, polygon spindle, 802g complete and probably tunable to 740g maybe.

    They are badass cranks, I have been talking with the guys there about a BB30 crank for my bike. they have a 30mm spindle but aren't BB30, they use a standard thread in BB so they are more versatile.

    I think they are worth every penny. plus they are made in California!!!!!!

    Bump....

    Avail.?

    I like the current standard bb and large bearing set up.
    I'm building up an new AM rig. The interface that they're using at the bb crank arm makes a LOT of sense. Great for this application.

    I'd love to use these cranks on this build!

    Anyone know anything more?

    any update on these? I tried to call, no answer. Also, is it for sure that the BB is proprietary (forgive me if that's a stupid question)

    Yeah...I'm seriously thinking about them to finish my Sinister Gruitr build...
    Since the BIKE mag article...there hasn't been much "buzz" about The Hive and these fifteen.g cranks! Bwahaha!

    hardtailnation.co.uk had a blip on them and said something to the effect that "they're new...so new that they won't be released in the US until June."

    Does any one have an idea as to whether the BB will accept speci's carbon crank?

    Whose crank?

    By, "speci"...do you mean Specialized? Unless they've somehow just adopted this new crank interface...I'd say, "No".
    If I've somehow missed something in your question....please...elaborate!

    it should work with the Specialized BB30 crank, the inner spindle diameter on each crank is 30mm

    I have been wondering myself if you can use the 15G BB on a normal frame with the Spec crank or the 15G cranks on the Spec BB30 frames.

    that's exactly what i meant. Thanks for reading between the lines . I've been back and forth between getting the fifteen.G setup or a specialized crank with the fifteen.G BB on my new bike (stumpjumper marathon 29er HT), but it'd be an expensive experiment if it didn't work out :/

    Just bought a set from my LBS for my singlespeed build - 32T - 175mm SS cranks. Seems very strong and decently light. I like the "theory" about the strength of their design, etc. We'll see.

    Are they compatitable with Shimano BB?

    bycy, did you get the version with the bashguard? any chance you'd post pictures of them on your build (haven't seen them on a bike yet)? what's your lbs?

    Yes - I got the one with the bashguard. I'd definitely post pix....unfortunately, still waiting for my frame from Soulcraft. Any week now...

    They really don't look too different from any bashguard equipped SS crankset, such as the Stylo. Although a bit cleaner lines and significantly lighter. The visual difference is really the spindle / bb.

    Nope - their new spindle design requires their BB.

    ah, hope it gets there soon! What I'm curious about is the bashguard setup, and the ring. I thought it looked a bit clunky in one picture I saw, but then I saw another where it looked alright. Do you know the bcd of the chainring? If you post a few pics of just the crank, I'd be really grateful!

    Couple of pix. The bashguard looks like it would fit if I ever changed to 34T chainring (NOT!)

    Let us know when you install em and start to use them. I have been interested in them, though the triple ring variety. My large ring acts as my bash guard and leg grater in one.

    Here is a picture

    Not the greatest picture, but here are the Fifteen.G triple cranks on my Salsa Ala Carte. I have a few rides on them now and like them a lot. They are well built and shifting performance is as good as any other crankset I've used before. Plus, they just look cool.

    If I understand the fifteen.g setup correctly, they will not work with a BB30 68mm bottom bracket shell? Kinda silly given the BB30-sized spindle and bearings.

    but the bearing width is 84mm so it adds more stiffness, they should work with the Specialized OSBB30 frames

    Once you guys have an impression on this crankset please post.

    Specifically if you notice any difference with the new spindle system.

    I definitely plan on getting this, been waiting for some first hand real word experience for these.

    Ok, so I put another 34 hard miles on the cranks this morning. I haven't notice any perceivable difference in the way the cranks feel while riding compared to other external bearing systems I've use (specifically Shimano XT and Truvativ Stylo 3.3). They are stiff and smooth.

    The biggest difference is with the BB/spindle setup when you first install them. With the Shimano and Truvativ BBs, you basically just screw it in and slap the cranks on. With the Fifteen.g, there are sets of shims and washers that must be put in to fine tune the spacing (between the BB cup and crank arm). I've tried to show a comparison in the pictures below. The first one is of my Stylo 3.3 setup. The second on is from the Fifteen.g setup. You can barely see the very thin spacers that had to be installed. It really isn't a big deal though because I don't pull my cranks off very often.

    Hopefully that was the kind of data you were looking for. I still have less than 100 miles on them so I can't really say anything about durability.

    Picture 1 - Truvativ BB
    Picture 2 - Fifteen.g BB

    For those that currently own them....

    Would you say they are strong enough for aggressive trail, AM type use?

    I have yet to ride them as I am still waiting for my custom frame, but I have friends that use XT on their DH bikes and I feel the 15G are up to the task as well. I would call and talk with Charlie at The Hive and get his response, I know he has been riding them for 6 months or so

    so far good

    I have been on my set for a month now, 175mm 32 tooth SS with bash guard. Setup took a little longer with the spacers but no big deal. I have been very happy with them so far. Especially since the q factor is low. (They play nice with my knees). Durability wise, I have smacked them into the usual rocks and what not we have here in New Mexico. I primarily ride and race on my single speed. My initial impressions are good. It is still too early to tell if the BB is any better than the other options out there. They are stiffer than my old xtr m952 cranks. I don't really ride aggressive trail, so I cant say if they are strong enough for surviving a cased 6 footer, so if your that worried about durability try out those new shimano SLX cranks maybe? I'll try and post up how they have done in a few months, for more of a long term view.

    Hi Calvinjp

    Regarding the Q-factor - did you have a chance to measure it? Please share it with fellow creaky knees riders.

    Thanks,
    Stefan

    q factor for fifteen g cranks

    I emailed the guys over at the hive and here is there response to me.

    "The Q -factor on our cranks is 84mm from pedal face to center. Like everyone we like a narrow q-factor but any lower than this and you start running into frame clearance and front der. clearance issues."

    This is very similar to the older xtr m952 cranks, this was one of the main reasons I switched. So far I have not had any knee issues Hope this helps.

    The 952 cranks are 163mm Q-factor, vs. 168 for the fifteenG. That's a fairly significant difference to me. On frames with clearance for ultra-fat tires I can see a lower Q being an issue, but I'd much prefer to give up a little tire clearance for the lowest possible Q.

    Maybe when the Hive comes out with a true BB30 crank (non-external) they'll take the opportunity to lower the Q a bit. I'm sure the new SRAM XX has a lower Q than this - it's doable.

    Edit: Just googled - SRAM XX at 156mm Q-factor option (!), also available at 164mm for frames that require it.

    I'm looking for a crank set that has significant clearance even with 180 mm crank arm length for my DW Sultan...wonder if fifteen G might be good choice ? Anybody know the Q-factor for RF Atlas crankset in comparison ? Thanks ! TIG

    Got my set of fifteen.g's installed. They seem awesome except...

    I'm having weird chain skip issues under torque, on the middle ring. I either get chain slip in the rear, or disastrous chain drop in the front (one or the other, seemingly randomly). My fifteen.gs replaced a crank with new chain rings, and I'm running the same (almost new) cassette, and rear derailleur. No chain skip before. Checked the hanger for bending, frame alignment, QR tightness, and the cassette for broken teeth and play.

    Any ideas or similar issues?

    How old's your chain. It is probably that or the cassette (even if the latter is almost new), or both.

    The issue is arising with a cassette and chain that had equal wear, only about 200 miles or so on them both. No problems with that chain and cassette with previous set up (though these were 1x9 and 2x9). Somehow, it seems this is related to the new crank. Or I am missing something...

    Try switching the old rings onto the new crank and see what happens.
