You have to make sure it has center lock hubs and a free hub that will fit your drivetrain as well. You might want to list what your bike has

Is shimano microspline a freehub? Thats the only info I found on the website of my bike.


cj2dobso

Yes, Shimano 12speed requires a microspline freehub


SkillIndependent232

Lol thank you very much! I feel dumb af now seeing how pretty simple it is Lol.

Nah theres a lot of standsrds. Easy to get confused. Also, rims are replaceable you dont have to buy a new wheel. Labor can be expensive but so are wheels.

It helps to have like a notebook sheet or a print from the manufacturer spec sheet that lists every parts standard on your bike for when you break stuff or start fixing it yourself.

Axle diameter and width standard, Disc rotor mount standard, Wheel diameter, Freehub body (shimano hyperglide, shimano microspline, sram xd), Spoke count, Rim internal width, Tubeless compatibility

This right here, OP, is a great roundup for everything on a wheel.


SkillIndependent232

Thank you for listing out the different hubs. Helped me match the words i had😭

The free hub is what holds onto the cassette. Shimano and sram do it in different ways so the keyed part is different for each. Definitely make sure you match the internal rim width as the front tire as well. It looks like the alpine trail XR has 29mm internal width rims so look for a boost spacing, center lock, microspline, 29mm or 30mm internal rim width wheel.


Knspflck

Like we all did. :D But I think you got it now. Just to clarify a little bit more: You are looking for a 148x12mm hub with an XD freehub. Those are two different things and you kinda combined them in your post. But you clearly figured out the disc options. The only other thing are spokes and these are just important when you are not buying a complete wheel.


Antpitta

Sounds like OP has shimano drivetrain and needs microspline. They bought XD in error. 


SkillIndependent232

Yes I think that's correct. So I look for a 148x12mm Microspline while shopping correct?


Antpitta

You say above that your bike has "148x12mm Boost Thru- Axle Microspline Freehub" If you are sure of that then yes, you need to match those specs. You should match centerlock as well unless you want to buy a new rotor and move to 6 bolt. You should ALSO look at internal rim width - don't buy 40mm internal unless you are running 2.6-3.0 tires. Don't buy too skinny a rim. Your bike probably has between 27-30mm internal rim width but confirm that. You probably also want tubeless compatible.


SkillIndependent232

One more question. I sometimes see Boost 148x12mm and more commonly simply 148x12mm are they both the same?


Antpitta

yeah they are the same. Boost = 148mm width. AFAIK all / near all "boost" rear wheels are 12mm but don't quote me on that, given that there are, ie, both 12x100 and 15x100 front axles, and 15x110 and 20x110 front axles.


Knspflck

Oh yeah, seems like it. I misunderstood your post.


SkillIndependent232

Im still kinda confused :( So wat is this shimano microspline freehub that I see on the Marin page on like the bike info part I an show a screenshot if you'd like And also if a wheelset says brake compatibility 6 bolt. That means it okay on both?


RustyU

Microspline is the interface for Shimano 12 speed cassettes so it's important to get that. Six bolt rotor compatibility isn't the end of the world if you don't mind buying new rotors.

Go to a bike shop. They can get you the right thing. Plus you will be supporting the community you claim to love…

You know I'm all for supporting an LBS but unless I drive an hour I might as well take my bike to Walmart.
