Real Info? 15mm V 20mm Through Axle

So for awhile now I've read constant complaining and talking down upon Shimano and Fox's new 15mm TA standard. It seems that most internet suspension guru's say that the 15mm is useless since it doesn't offer much weight savings and that its much weaker than the 20mm.

I know there was a thread awhile back when this stuff first showed up, but I still have not once, read a bit of solid facts proving that 20mm is that much better.

I am going to be buying a 15mm QR Fox fork soon since my wheels won't accept a 20mm. Let me say however though that I would prefer a 20mm pretty much based on what everyone on this forum says even though I don't feel like there is any real evidence. Also it seems from reading feedback that the rockshox chassis is more stiff than the Fox which was another reason I was going to go with the Rockshox with the 20mm TA, plus the price, etc, etc. At the same time though I can't imagine that there is really that much of a difference between the 15 and 20 but it seems some people believe there is?

I'm not really tripping too much, I'm not in denial and I'm okay knowing that the 15mm might not be as stiff as the 20mm. I would however like to see some actual proof to these claims though so I can know for sure what I'm getting and why it isn't as good as the other option.

So please share some data or evidence if you have any that 15mmTA is just a marketing ploy and inferior to the 20mm that its really worth mentioning and not buying a 15mmta.

Thanks

Your going to like the 15 mm TA alot. I have one and it is a huge difference from a QR. On the other hand, the difference from my 15mm to my 20mm is not as noticable. Of course this is a pure "feel" thing on my part, no data backup,charts or graphs. Enjoy!
I don't remember where the charts are..but there were some around..

I remember that also and if I remember correctly, a fox 15mm fork had roughly the same level of stiffness as a 9mm zoke or Rockshox.

There was a lot of disparity in those charts, and as far as I remember nobody ever commented on my posts regarding conclusions drawn based on it in some old long thread...

Thanks for the link, a good read but the magazine test is far from a conclusion

Both are better than a quick release.
For sure.
I have been wondering, after better than a year of the 15mm TA being around, what the general opinions would be.

I have been on the talas 150 15mmTA since nov of 08, went with a new bike at that time so not a back to back, but for what it is worth, my two cents.

My old bike had a talas 130. I run 203 rotors on both bike. On the 130 QR the rotor rubbed a lot going through turns. On the 150 15TA I have yet to get a rotor rub. Is it due to brake adj, updated lowers or the TA? Cant say for sure, but the front end feels great. :thumbsup:

I would never go back to a QR after having a TA, no comparison.
Stiffness is more than just axle size too. If you feel like 15mm isn't stiff enough check out this hub. Well priced and very stiff. Also with that hub you have the ability to switch between 15mm and 20mm axles.
