BigRock carbon crankset with 24mm titanium spindle

Can someone with an Xcadey PM and Shimano Chainrings confirm the correct Xcadey spider is the SRAM 3-BOLT 110BCD-4 version?

Exactly the same issue I was trying to resolve yesterday. My main reason for tinkering was to try to eliminate intermittent outboard chain drops with an Ultegra 12sp FD w/Pass Quest chainrings & Xcadey PM on a Speeder SC-R55.

The FD's limit is maxed out and still tries to push the chain too far at least once or twice a ride, which is significantly more than I feel is acceptable. 3mm & 2mm - shifts on point, but completely binds up at torque. 1mm DS torques down properly with the ability to adjust preload, but it's then back to the same issue. Having said that, in the bike stand, you can bang the chain up and down no worries, and only around 1-2 times will the chain either drop or ride the teeth before popping into gear. Take it out on the road and it's roulette. For the most part, it's been fine, and the chain will jump back on after a few pedal strokes. However, it's not without a few cursory scratches to the cranks.

I've not got around to trying it yet, but my next port of call will be to try to remove the preload from the equation and attempt to use spacers to load and shift the crankset over into a decent chainline. Wonky Q factor or not, I'd rather not have the chain keep dropping mid-ride.

Keep us updated. I have chaindrop issues too and I cant replicate them for now. Not sure the issue is in the crankset, it shifts fine under the load and on a stand... Might consider tinkering in this direction.

I can confirm

Did anyone try to remove the decals? Was it easy or is there a load of clear coat on top?

Doesn't look like the seller can ship these cranks to Europe, which is a pitty. Is there a way to purchase them directly from Bigrock? Anyone got a contact?

There are a bunch of shops/storefronts selling these. Some of those ship to Europe - usually on the more expensive end of the range, but ship they do nonetheless (or at least they don't say they don't).

Just for reference, XFRRY BIKE Store has several listings. This one should say ~250 USD shipped to Germany before coupons and stuff: https://de.aliexpress.com/item/1005009175039163.html?

AFAIK there is not a single listing below import duties threshold and neither any seller offering prepaid import handling. Not the end of the world, just a bit more hassle on your end (depending on local customs and stuff).

I am in touch with xfrry store in whatsapp since aliex store cannot send the cranks directly to me, though I’m having trust issues atm lol, did anyone here transacted to xfrry store directly in whatsapp?

I'd use a credit card with strong buyer protection and roll the dice buying direct. Less likely to get a shoddy crankset versus a shoddy frameset.

Just received a 165mm chainset to replace my 170mm following a bike fit. The box is marked 165mm Road but the Q factor is massively wider and the 170mm being a much flatter design. I messaged the seller, xferry, who told me they have changed the Q factor “to be more compatible with shimano systems”. Afaik shimano 12 speed cranks have a 148mm Q factor. Are they gaslighting me  and they’ve sent me the mtb ones by mistake? Or does this seem genuine? It’s not listed on the ad.

I’m going to try them anyway since the bike fitter already added 4mm total spacers to increase my stance.

Have you installed the cranks and measured the outside-to-outside from there?

Looking at the different listings on Ali the older ones are 140 and the newer ones 146mm. The difference between yours do look a lot more, but yes, you would have to mount them first to get a good reading. If they are MTB I would expect the axle to be much too wide for your roadbike... 

I bought these cranks a few months ago, and found them too narrow for me. Had to max out spacers on the BB and the pedals.

Edit: It also looks like the MTB crank arms look totally different and the axle is DUB, so no way they could be swapped.

Since I am also interested in these I just asked XFRRY on Aliexpress.
They replied the two listings (q factor 140 and 146 mm) are the same product, just one listing has an actual photo of the crankset.
Q factor is 146 mm except for 165 mm crank length, where they sent me a photo that shows about the same Q factor as on the picture here. Sounded like other crank lengths will also get a wider Q factor in the future.

The crank arms in pics are both at their maximum insertion on the spindle so if anything on the bike it will slightly wider depending on spacers used. Both old version and new version have the same interfaces and arm thickness.

True about mtb being dub I hadn’t considered that. Yeah actually I’ve been struggling with increased knee pain since switching from ultegra 12s cranks to the 170mm bigrock, hopefully my new 165mm’s increased Q factor will help if they were just too narrow

Interesting! so they’re not having me on it seems they genuinely are increasing it.

These stupid fucking assholes! Those were the only cranks with a somewhat acceptable tread width. It's going to be such a nightmare to return these and get the import fees back ...

Haha calm down dude! I have a set of 170mm for sale if it’s off interest?
