Well, thanks a lot guys! NOT!!
Just ordered the crank for £59.... Didn't think to order the shims.... But I won't use the crank for a while anyway.
Obviously justified this to myself by saying I'll need a 24mm crank soonish anyway.... and that I'll obviously pedal faster on carbon cranks....
Will be selling the oem 32t ring though.
Ahem.... 😊
Blimey.... Don't think I'll bother with a genuine Eagle oval, too expensive.... I'll be fitting a Works/AB oval I think.
I've been running an AB ring for ages on my gx eagle setup anyway and they are great.👍
Still £69 when I looked too.
Good call poops, I’ll bet the upgrade is almost cost neutral by the time you sell you turbines!
Silly question, but isn't SRAM x1 11 speed only? I though eagle was only nx, gx, x01 and xx1?
Can you get an adapter for race face bb9 to gxp?

I think you are right mate. I'm excluding the new BB cost as I will need that soon one way or another anyway.
Quiet a bit of choice for the oval ring these days.... Though I'll probably pay the extra for the AB one as they are so pretty.lol
Okay - I’ve ordered some too (see my post on wobbly race face next rally cranks.....)
So what actually is gxp? Is it just a 24mm b/b? I have a Hope pf30 currently - I think you can get an adapter for that? Or could I use a 24mm hope b/b?

In truth I'm not sure either. Someone mentioned these are oem? Perhaps that's why.
As long as they are carbon and have an eagle ring on I'll be happy.👍
@Charlie
I think you can use an adapter. That's my plan till I have to change the BB anyway.
Mine didn't come with a wavy washer, should one be in the box?
Cheers
Wasn't going to bother, then I saw people selling them on ebay for £160 and thought nothing to loose either way. I was really after 170 32 tooth but ended up with 175 30 tooth, but cant complain for the price of a chainring.
I either need an adaptor for a raceface bb90 to gxp or a non boost chainring depending on what bike they go on.
Cheers for the PSA OP

Good question, anyone?
You dontnuse wavy washer on GXp I don’t believe, my descendants don’t. The smaller non drive side axle fits into the bb so no need to preload. Like I say my current GXP cranks with hope bb have no way of preloading, have no play and are frankly superb
The wavy washer is to hold the DS seal against the bearing. You wouldn't need one with a Hope BB as the seal can't move anyway, but for a lippy contact type seal you need one. One came with my Wheels mfg. bottom bracket (a gxp specific one) as they have that type of seal, it also came with some washers in case the gap was too big for the wavy washer to bridge.
You can get O-rings off ebay etc. to do the same job apparently.
GXP is 24mm then tapers to 22mm on the opposite side so you need a GXP bottom bracket.
A standard Shimano 24mm will not work.
A standard 24mm bb will work with spacers eg the ones for Hope. I used to use my SRAM cranks with a Hope BB and Hope spacers on the NDS, it worked fine and didn't need a wavy washer. And of course, the DS cups/bearings are the same whichever, if you like to pick 'n mix.
Greyspoke & dhrider have the BB compatibility sorted for external threaded BB’s.
As for the X1 Eagle 12 speed question, these look like OEM products - as they come with no aftermarket packaging.
I imagine these are fitted from the SRAM factory with Eagle rings for a production bike.
I think the wavy washer thing is the same for PF92 types, my gxp cranks are currently in a frame with a PF92 shell. The difference from external threaded cups is the way the cups fit in the frame and the frame bb shell. The bearings are the same type and the same distance apart and most bb manufacturers probably use the same seals as well.
Okay - I currently have a hope pf30 bottom bracket. Can this be adapted for gxp or do I need to get a hope 24mm b/b for the hope adapter to work?
Hope that made sense!!
You need a Hope 24 and Hope GXP adaptor kit. That’s what I use.
I dunno charlie I have never used pf30. But there is this:
^^there you are then.
Give Hopetech a ring and they will tell you which parts you need to make it fit.
Never seen that before greyspoke - that looks like it would work fine.
Mine arrived yesterday. As others have said these look like OEM (no packaging) but come with the Eagle (x-synch 2) chainring. Not surprisingly they were a straight swap for my GX Eagle GXP cranks (5 minute job). I’m using a 24mm Hope BB with the Hope GXP adaptors. No need for any wavy washer.
Perhaps a bit more surprisingly the total weight saving over the aluminium GX Eagle cranks was 67g and that includes dropping from a 32 to a 30 tooth chainring. But they look nice and barely cost any more than the chainring, which is what I was after.
I tend to get a bit of heel rub on cranks, so it was nice to see that they come with a bit of tape in the relevant area already.
Oh and the X1 Eagle chain that Wiggle marked as 9-speed in the description is, of course, 12 speed really.
I’m glad quite a few of you found the PSA useful.
Roverpig, what did they weigh with the 30t chainring on?
564g according to my kitchen scales. That’s as they came, minus the protective plastic cap over the splined end of the axles and the two pedal washers in a bag that were zip tied to the other crank.
GX Eagle cranks with 32T ring were 631g in the same state on the same scales.
570g with 32t chainring
The 2 washers obvs for the pedals,yeah?
Yep
Do these cranks have carbon arms? Some descriptions say they do but mine arrived today and are scratched on the nds arm and it’s silver underneath.
I currwntly run 10sp.
If i wanted a 10sp chainring, what do i buy? It has come with an x-sync 2 ring that i think is eagle 12sp.
Perhaps a bit more surprisingly the total weight saving over the aluminium GX Eagle cranks was 67g
By shear coincidence i'd seen those sort of figures just before the Wiggle deal happened - it made them annoyingly hard to convince myself to buy!

Mine are definitely carbon. Are you sure you ordered the right ones...?

As mentioned in the other PSA thread - SRAM make some lower level carbon cranks that don't really save any weight against say, the GX Eagle crank arms.
If you want a decent weight saving, you need to go up to XO1 or XX1.
Well being carbon skinned aluminium/aluminium cored carbon would explain the modest weight saving?
Wiggle quote the X01 as 546g.
This set of X1 Eagle is 568g so there is very little difference in weight. If the X01 is the premium carbon and this is the budget then maybe its juat super hard to make a chainset even lighter.
These are about the same weight as a pair of Raceface Sixc. The new Next cranks are about a 100g lighter but I would not run Raceface carbon cranks again. I actually think these are about on par for a decent carbon crank weight

Wiggle is quoting wrong. There is about 100g difference, according to Sram.
Its a good point, how do you know if these are carbon? Its not like the description was accurate.
I just cant tell. They sound quite different tapping them compared to my x01 dh cranks that I know are carbon.
I needed 170mm 32tooth boost cranks anyway, but would still be miffed if they weren't carbon even at that price.
They sound like normal alloy cranks if you tap them.
Mine arrived today.
Will store them till I need to fit a new BB.... so won't be long! Lol
Weighed in at 590gms on the NASA approved kitchen scales.
That's with a 32 ring and all the packaging plastic etc still attached.
Definitely carbon. I own a metal detector. No really,I do.
Don't care about weight though... they are caaaarrrrrrbbboooowwwwwwwwnnnnnnnn!!!
Also means I can fit a decent/serviceable 24mm BB and get away from non serviceable PF92.
But, it's really all about the ccaaaarrrbbbooowwwwwwwwwnnnn.👍
Thanks op and Tracey on the other thread!
Glad everyone got the bargain they wanted. Fitted the chain ring along with a new chain and cassette last night so she is now ready for the next race. Cranks have gone in the spares box for when we need them. I couldn't tell any difference between the XX1 ring removed and the new one fitted.
