I own a 2018 Bianchi Infinito that for some reason used a 12x135mm through axle. Anyone know of any carbon, disc brake, rear wheels that would fit this frame? Plenty of 142mm wheels around.
A link would be great.

How did you arrive at that number?

135 is generally a quick release size and 142 is the exact same hub set up for thru axle. Even the spacing is the same, just the dropouts are machined 3.5mm on each side.

Have you tried a 142mm hub. I bet it’ll slip right in.

Probably because that is how Bianchi spec'd it...https://www.bianchiusa.com/archives/...-disc-ultegra/

OP, 135x12 is rare, as you know. The only ones I found (doing a 2 minute search of google) were on European websites, and built wheels with 135x12 hubs were exorbitant, like 5000+ Euros for a wheelset. I'm sure with a bit more searching, Google has lots of neat stuff, you may be able to find them for less....or find a reputable wheel builder, explain your issue, and I bet he/she will recommend buying a 142x12 rear wheel, and then swapping the end caps to reduce the overall dropout to dropout dimension from 142 to 135...which requires a reduction of 3.5mm per side, as stated above.

That's a bit more unfortunate of a spec. I don't think you can machine the end caps off a 142mm hub, because it'll place the last cog too close to the frame if done on the DS, and alter the location of the rotor on the NDS relative to the Frame, if I'm not mistaken. Most builders can probably get Chris King hubs in that configuration--also, Bitex makes a hub that's available in 135x12, but it's hard to come by, found one here: https://bitexhubs.co.uk/product/bx207r/. Some vendors also have Hope Pro 4 in that sizing. if you're considering carbon the Pro 4 is a pretty nice sanely priced hub. There's also this: https://bdopcycling.com/product/xd612sb-cl-11/ .

You could just buy a hub set from bdop and hand them to a local builder, with or without rims (I like Nextie for good, inexpensive consumer direct carbon from China). Don't try to shop for spokes for them--they will probably want to confirm measurements themselves before committing to spokes. Could have a pretty nice wheelset for well under a thousand.

No, a 142 will not fit. The axle is clearly labeled as 135x12.

Thanks man, these are some good leads and ideas.

Wow, I guess it does exist. Bike manufacturers are awful sometimes.

The early disc road bikes were a ****show of standards. We have, in rough order of commonality:
135x9mm qr
142x12 ta
130x9 qr
135x12 ta
Specialized scs (weird 135x12mm ta, but slightly different!)

I'm probably missing a few abominations.

There's also the slightly annoying, mostly useless transition from 100x15 ta to 100x12 ta front axles, but I can live with that.

I don't know about wheels, but hubs in that size are not that hard to find. It's somewhat common for heavy duty stuff like DH bikes. The Shimano Zee hub is available in 12x135mm: https://www.ebay.com/itm/18423240776...oAAOSwkztgOmkU

You can also order these kinda generic hubs with various axles, inlcuding 12x135mm: https://www.bikehubstore.com/MTR-p/mtr.htm

cpach is correct. 135 mm through-axle hubs were a transitional stage before we settled on 142 mm hubs (which are really the same, except for the addition of "shoulders" that fit into recesses in the dropouts, making it easier to position the wheel). They're orphaned technology now.

DT Swiss has caps available for 135x12 TA.

What would be different about the Specialized? I assume the scs means short chain stay, which also means a slightly asymmetrical frame, but apart from dishing the wheel toward the non drive side, what other gotchas could I expect?
I ask because I have a prospective customer that wants a new wheel set for her 2017 Specialized Crux, which she tells me has a 135 x 12 rear hub. I have not yet laid eyes on the bike to assess the situation, but she has an appointment with me on Monday so I can scope it out.

I deep dove on this year's ago, but can't find the document detailing exactly the dimensions now. Scs is designed around road chainline, other 135x12 hubs are designed around mtb chainline so the spacing is subtly different and they are in fact incompatible. I'm sure there are hacks with end caps etc but the literal only two hubs that Just Work that I could find are the 24h Specialized hub the stock wheels came with and a specofic run of Hope Pro 4s. I ended up getting a Specialized hub from a dealer in our area and building it to the burliest rim I could source with ds nipple washers and the highest tension I felt comfortable with.

Dan Burkhart 

Thanks for that. Good to have a heads up going in.

135mm M12 Rear hubs are plenty available.

Otherwise my customers wouldn't be bringing em to me all the time for custom builds.

I've gone down the rabbit hole on this issue thanks to you. No really, thanks a bunch, because you alerted me to the fact that this will not be a simple plug and play. Lots has been written about this, some of it by people that actually know their stuff, but it takes some sorting.
This is one of the more informative sources I found. https://builtbyjerry.com/blogs/news/...ail-me-i-guess

They sure were. I own a road bike that has a 100x15* ta front wheel, a 135x9 qr rear wheel, a flat mout disc fork, a post mount rear end and wouldn't you know it, a rear rim brake bracket ... Talk about a **** show! :-)
