Is a thru axle a thru axle, or are there differences?

I have a Cannondale Habit with a Rock Shox Recon fork and Formula hubs. The rear is a 142 x 12 mm thru axle and the fork is a 100 x 15 mm thru axle.

The thru axles are different brands (front is KCNC and rear Formula)

I am keen to replace both with stealth type axles.

 

Are all 142 x 15 mm and 100 x 12 mm thru axles compatible, or are they bike / fork specific?

so, thru axles have different thread pitches. The fork will be easy to figure out as RS use a 1.5 pitch and a replacement axle usually specifies if it's a RS replacement.

 

The 12mm rear axles differ. Some have a 45 degree bevel, some are flat and, the pitch as well as overall length.

 

So measure your length, check the bevel/flat lever end and then google the thread pitch.

 

That way you can get the right one

  • M12x1.0 — Scott / Santa Cruz

    • Fine thread. 168mm length with 12 mm thread length

  • Used by Santa Cruz and Scott. Santa Cruz models come OEM with a DT

M12x1.0, 167mm length with 20mm thread length. Maxle Stealth is available for Santa Cruz / Scott

M12x1.0 — X-12

  • 161 mm length

Used by Specialized. Syntace X-12. Inga’s BMC hardtail uses this.

M12x1.5 — E-Thru

  • Shimano rear E-thru 12mm “standard”

171 mm length, 18 mm thread length.

Used by BMC, Giant, Lapierre, Rocky, Yeti, Evil Following, some Kona models (not mine)

M12x1.5 — 160mm length, Road

  • 160mm length, 20mm thread length

Available as Maxle Stealth

M12x1.75 — Maxle

  • Rear Maxle used by Ibis, Niner, KTM, some Trek models, a BMC model. Some Kona models too (turns out this was the size I needed)

174 mm length. 20mm thread length

This is just for a regular non-boost rear thru axle. There’s also the boost 148 length. In the 12x148mm “standard” you need to choose from multiple thread pitches as well.

  • M12x1.5 — Boost E-thru

    • 170mm length, 10mm thread length

M12x1.75 — Boost

  • 180mm length, 20mm thread length

Plus there are additional lengths for Split Pivot bikes and Trek Boost ABP.

Really handy that manufacturers make guides like this, One-Up has a similar one on their website.

 

I thinks something like the SRAM Universal Derailleur Hanger is a step in the right direction, it has M12x1 thread and the idea is to be compatible across a number of bikes.

 

 

Have found the attached Wolf Tooth rear axle guide very useful especially when ordering axles for IDT setups

As long as bike manufacturers can sell hangers at 500 plus ZA rondts I can't see them going for any standard... I mean there's that one that even sells a different hanger depending on whether you are running SRAM or Shimano for crying out loud [emoji848]

the thread may be different

someone made a thru axle first.

please can we name and shame the moron who was:

a)too lazy to keep it universal

b)evil enough to make their TA proprietary

Its like Cannondale does EVERYTHING different just for the sake of being different.  In afrikaans its the oke who is always "dwars".  

 

(And I own a couple of 'dales so I think I'm justified to bitch about this).
