    Spiderless cranks and intended use

    Sorry if the title makes no sense. Out of curiosity I'm trying to get a handle on whether manufacturers of spiderless chainring-capable cranks are aware of, or support, the use of spiderless chainrings.

    When looking at product descriptions of cranks with removable spiders (well OK, just Truvative) I notice that they don't seem to try to emphasize, note or promote the fact that the spiders are removable. It would seem that for may consumers this would be a selling point that could cause them to choose one crank over another.

    Also, that there seem to be so few sources of spiderless rings suggests that spiderless use is not something that crank manufacturers are keen to encourage. Does this ring true (no pun intended), or are there other aspects to spiderless chainring supply and demand?

    Also, exactly how safe are spiderless chainrings (which seem to be a bit of an improvisation) compared to standart bolt on cranks? Just wondering about all this since I started reading about spiderless while trying to see if I could get a < 32 tooth chainring.

    Been riding an X7 crank with a 32T HBC spiderless chain ring all year with out any problems. Don't see any downside.

    The crank, rings, and bearings all see the same forces regardless of whether chainring bolts are present. Spiderless is no less safe and actually more reliable since there are fewer parts to come loose or fail, and it's a little lighter as well. There are many instances in which this industry has lead us away from perfectly adequate designs in order to maintain profitability (sorry for the cynicism).

    My White Industries Eno crank has been very solid,
    chain ring has held up great with little wear with
    over a 1000 miles on it, no more chain ring bolts
    to check and it minimizes uneven chain tension.
    Crank is coupled with Phil Wood BB for a very
    smooth drive train.

    Very nice, is that an HBC ring (looking for alternate sources)? Edit: Just checked out the White Industries site and see its a chainring of their own design.

    No need to apologize. Just seems that in this case there is an opportunity for manufacturers to run with this and provide a useful product, but it seems that only a few vendors have noticed this so choice is limited.

    Here is my set up. I am actually surprised SRAM does not make a spider less ring their own.

    I'm running X0 cranks with a hbc ring on my Ragley TD:1 and I just orfered some MRP spiderless rings for a set of X7s I have laying around. The X0 crank, ring and bb come in at 586grams.

    I guess that's about 10 or 20g lighter than crazy8's SS-modded and tuned M960 crankset?

    This is also what I was thinking. Makes me think they designed the spiderless interface with some other purpose in mind.

    It makes sense to me that a manufacturer would go for a spiderless set-up, especially when they're making carbon cranks. Spindle interfaces need to be alloy and it would be cheaper to design for spiderless than to design and manufacture a carbon wrapped one piece spider/crank. It also gives them the option of utilising spiders for 2x & 3x cranksets without needing to redesign the whole crank. Now they still have the option of going 1x on the same crank, without extensive devolopment costs, which they will, especially given the introduction of XX1. No doubt that they were probably involved with MRP and their design. Sram will probably release something better looking soon because quite frankly, the MRP looks "out of place" with that grey colour and the shape of the chainring arms.

    As with most designs, the basis is usually cost driven.

    What I find strange is that the xx1 is spiderless and uses a spider and chain ring set up.

    They did that to facilitate chainring swappage. Yes, swappage. Gotta take the whole crankset off to swap spiderless chainwheels. And the torque spec on that 8mm retaining bolt is 416-478 in-lbs. Try that with a 4" allen key!

    So are there any other sources of spiderless chainrings? Experimental Prototype in Sweden just announced they won't be making rings any more...

    MRP just got in a new batch of rings. Mine were shipped out 2 days ago.

    Who else makes then? Besides HBC.

    The bling-rings are sweet, thanks for sharing the link! Makes me want to go out a buy a sram crank.

    Anyone want to buy an LX (spiderless) crank 175mm?

    Ok, so there's HBC and MRP (SRAM only). EP is out. Any more suppliers i.e. for Shimano?

    Is it possible to buy just the X0 left and right crank arms instead of buying the entire cranks set. I would love to go with a spiderless setup and use a 30 tooth upfront.

    Seriously thinking about using this SRAM X0 set-up as it's the lightest (but strong and tough) SS splined crankset I can think of. Does anyone know where I can buy just the cranks without the spider and rings, and then a decent bling ring to go on the cranks? (in the UK... ??)

    If you have a BB already you might want to look into getting the XX1 crankset. Sell the spider to offset some of the cost and then getting the MRP bling ring or the NSB chain ring since the XX1 crankset can be had for about $240 new(without BB) whereas the X0 stuff usually cost a bit more than that.
    I'm actually building my first SS and should be receiving my XX1 crankset and 30T bling ring in a couple of days.
    I will take some pictures and report back when I get it but there is another thread where others have tried this set up and been pretty happy with it.

    Is it possible to run this setup without a chain guide?

    If you are talking SS, then yes.
    If you are talking 1X then yes if you are running a shimano shadow derailleur or SRAM type 2.

    There are more manufactures of spiderless chainrings for SRAM coming out. Some with the alternating tooth profile like the XX1 rings. Wolftooth is testing theirs out now. wolftoothcomponents.com

    I must admit that makes sense, but I thought I read somewhere that the spider was not removable on the XX1 but is removable on X0 - is this not true???

    The spider is removable both on xx1 and x0. You can use the xx1 spider on a x0 crankset.

    I think you have the xx1(11 speed) confused with the xx(10 speed). The xx crankset spider is not removable. The xx1 spider is removable like the x0

    Yes you are right.

    The XX1 set up will work out 50-60g heavier than X0 though, by my calcs, including BB.

    I have one. 62g for a 34t SRAM spiderless ring. Looks nice, but have not tried it yet. Waiting for my Ti HBC ring to wear out, so it could be a while!

    Just received my XX1 crankset and 30T MRP Bling ring.
    The XX1 GXP Crank arms weigh 476 grams
    The XX1 32T chainring and spider weighs 94 grams
    The MRP 30T Bling ring weighs 56 grams.

    The Bling ring was a tight fit onto the crank but I suppose tighter fit is better than a loose fit.
    Anyone happen to know the torque spec for those 3 bolts?

    pwu_1 - I see you're just across the water from me - please could you tell me where you bought the XX1 and bling ring? (I'm presuming you hunted down a good deal!)

    Any chance of pics?

    The cheapest price I found on the XX1 crankset is upgradecycle.com They are selling them for $241 with free shipping in the US. Took them about a week after ordering before they shipped. Make sure you order the right Q-factor cranks for your bike.

    The cheapest bling ring I've found is $57 with $2.99 shipping in the US at universalcycles.com They are out of stock at the moment though.
    I found another place called benscycle.com where they are selling the bling ring for $69.95 plus $2.92 shipping but they had a 15% discount code(SRCH15) which brought the total price down to $62.38 They shipped the 30T ring a day after I placed the order

    I thought from your profile you were in Dublin (I'm in the UK) but if you're shopping in the US I must be mistaken.

    What BB shell for this spiderless crank set?

    Anyone know what BB shell these cranks are designed for?

    I'd say its a normal 24mm spindle which means gxp bb which means 68 or 73mm English threaded shell. But don't take my word for it. Ask the seller

    I'm using XX1's on 2 of my bikes. The best weight weenie combo I have found is the BB30 cranks using e13 bb and a 28t bling ring. They came in a 584 grams. They are on my On One Scandal. this combo works with most 68mm BB shells.

    Did you ever find a UK online shop that sells it? So far I've only found this link: Ison Distribution
    via the mountainbike forum of Belgium (where I am from).

    Don't know where the dude got the bling ring from but he is in North Wales. I'm in the south east. It was on a set of X0's. Paid £240 for the set, and it hasn't been used.

    It's gonna be on my Ti rigid singlespeed in a couple of days, hopefully... as long as he posted it!

    Cranks arrived. Look awesome. 523g without BB but with the 32T bling ring. Looks like the MRP bling ring came from Evans (UK):
