So the dreaded 141 x QR question. Anyone know of an off the shelf cheap 27.5" rear wheel?

I'm pretty sure its a boost 148 hub with narrower adapters - but?
That's exactly what it is. What's your definition of cheap? Do you prefer to shop online or do you like keeping money in your local economy?

Anywhere i can get one in the UK. Shimano MT200 hub fits the bill, but can't find a built wheel. But ideally around £120

All axles thread like a regular bolt. Righty-tighty lefty-loosey. If you shear the handle off, be prepared to drill and use an easy out.

Yea we used an easy out so now i have another question. Idk what thru axle to get, i.e. do i have to get a maxle thru axle or can i get a regular one?

20mm Maxles on Boxxers should be replaced with genuine maxle replacements. Any other maxle (15mm front or 12mm rear), I would strongly advise replacing with something else. Maxles are overly expensive and more prone to failure than many alternatives.

However bear in mind I hate quick-release things in general, so I am a little biased here...

I'm a fan of Burgtecs offerings re: aftermarket axles. They are well designed (for example not having a stupid taper that leaves your driveside rear hub main bearing completely unsupported!!! Looking at you Syntace...) and a good price.

Yes, the Suntour Zeron cranks use a 24mm bottom bracket, which is compatible with Shimano Hollowtech and RaceFace. It is NOT GXP compatible.

So, Shimano Zee cranks with a 73mm width are probably your best choice.

Thanks for the response. https://vitusbikes.com/products/mythique-29-vr-bike-deore-1x10

So is this a typo on their website? A Shimano Zee would be ideal, I think, if correct. What about the chainline? The 53mm BOOST issue.

Upon checking with micrometers, the crankset has 23.97mm and 23.96mm axle diameters. So I guess we'll be using a Shimano or Raceface Crankset. The next question is about that chainline. It appears a Shimano Zee will NOT work.

Yeah, non-Boost cranks often work fine on Boost-spaced bikes, but in your case, it's unlikely that the Zee cranks would fit unless you mounted the chainring on the outside - which would give you a chainline closer to 57mm and limit you to a 30t ring as the smallest.

SLX cranks are a great option for the money, except for the proprietary chainring spacing...

I suggest RaceFace Aeffect. You can use the same BB, and you'll have a large option of RaceFace and third-party chainrings - direct mount, and otherwise.

You'll need a cassette, microspline freehub body, chain, derailleur Shifter and compatible chainring.

You'll need the appropriate freehub body for your hub.

But yes, Hope make a microspline freehub

Pretty sure Sunrace make a 12sp hg body cassette. Might save the cost of the freehub body swap for now.

You can also work a Deore/SLX 11/12 speed rear derailleur with your 11sp shifter and run a wider ratio 11-51 cassette if thats what you are looking for.

New question for a pretty new bike with a SRAM (Eagle?) AXS derailleur.

Ideally I'm hoping to fix myself or work with SRAM. I noticed sometimes when shifting to a harder gear, I hear the digital AXS noise right when I hit the paddle, but the derailleur doesn't move. I've noticed this happens mostly when riding statically on the bike, like on a climb on the saddle, and when I change the compression/sag, it does something to initiate the shifting, and does shift fine into gear. So usually it's fine on the trail. Taking a closer look putting the bike on a stand, the issue is more apparent: I hear the noise but the derailleur usually doesn't move, especially going to a harder gear. The only thing I can think is that it's a chain length issue? Firmware has been updated, but same issue. I don't think it's a micro adjust thing, because there's no shifting noise or delay besides the main pause, but I could be wrong. Basically, it's almost like it works fine on trails as they're usually bumpy enough for any small bump/change in shock compression to 'help' the shifting, but if I were say climbing up a road and not moving around a bunch, the derailleur many times doesn't respond, until I get off the saddle. Thanks for any help.
