Ok so I have an opportunity to run either a 12mm or 10mm on my new dh bike and I am on the fence as to which to run. At this point I am running a 135mm x 10 I9 hub with a hadley bolt which is really great but I am being forced into the 12mm option due to availability.

My question to everyone is do you notice a difference with the larger axle? Is it worth just going to the 12?

I am trying to keep this bike light as possible because i will trail ride on it a bit but i am not sure if there is even a weight penalty with the 12, if that is case i might just stick with it and build a new rear wheel.

Thoughts? Thanks.

the main difference would be that most 12mm systems are dedicated through axles. which in theory would be stiffer.

i dont know what your 10mm drop outs look like.

the vp free has a 12x 150 hub, but uses a conventional drop out design, so it kinda doesn't take advantage of the 12mm axle.

 

[demo8razor]

not to steal the thread, but are you familiar with a demo 8 frame? it has vertical drop outs and a bolt on hub right now, they call it a hollow thru axle and 135 spacing I will be building wheels later in the year. what hub would i want just a bolt on if made, or a 10 or 12 thru axle?

 

[demo8razor]

also with regard to the first question, what i asked, can kind of answer it too, but i don't think theres that much of a weight penalty from a 10mm axle to a 12mm axle, i just am not sure if all bikes will accept a 12 or a thru axle at all

The 10 mm was just a standard mtb dropout on my bottlerocket. My new bike comes with either a 10mm or 12mm (blindside) but the 10mm are not available. I wanted to stick with the simple 10mm but that just isnt an option.

I am wondering if i should plan to go back to the 10 once available or just run the 12mm. Keeping in mind i like the simplicity of the 10mm and low weight. Like said above i cant imagine the 12 weighing much more few onces possibly which i could care less about.

 

[demo8razor]

so the 10 was like mine, a bolt on? where the 12 is a true thruaxle?

 

[demo8razor]

you're from pittsburgh? where do you ride normally?

 

[manhattanprjkt83]

All over man, as for dedicated dh trails we have none but spend most weekends at resorts...Springs, snowshoe, wisp, diablo...we are working on some stuff...travel alot as well.

yeah just like a qr dropout im only 160 lbs never had a problem with it anywhere even at whistler and places so i dont want to go overkill. I am assuming the 12 is the closed true through axle system i just dont know i need it

I couldn't see much of a weight difference, especially if the 12 mm axle is aluminum.

 

[demo8razor]

how is springs and wisp? im from northeastern pa, and sometimes am in state college so wisp and springs arent too bad of a drive from there

weight wise, no noticeable penalty unless you jack off to your bike on a scale more than you ride it.

stiffness wise, you'll be much happier.

This is exactly what im thinking...This might end up being a good thing for me...I watch weight but dont go crazy...

if you're going from a standard QR/bolt on 10mm to a through axle, and you ride DH, there really isn't a reason to stick with the 10. Go 12, the stiffness will pay off.

 

[dhkid]

definitely go with the 12mm man.

IF you do still want to run the 10mm, you can get 12mm to 10mm step down axles that just fit in your standard 12mm hub.

Do you know anyone who makes them in aluminum? I just could find them in steel.

Ok well I will chime in here as I am upgrading to a 12mm from my current quick release. I did as much research on this as possible prior to making any decisions and I had kind of the same criteria; low weight, added stiffness. I know just going from a QR to a 10mm thru axle made a huge difference in stiffness (I swapped wheels for a weekend) so I figure going to 12mm would be a little better without really sacrificing much in weight. I found a site that sells Hadley parts and they have the weights listed for the thru axles. The 10mm axle was listed @ 56g and the 12mm axle was listed at 74g. Both of these axles are for 135mm spacing and are aluminum axles.

To the OP: you said you were running an I9 wheel. If its the right hub you can change it from QR to 10mm to 12mm. That's what I'm doing to be able to run the same wheel with a 12mm thru axle.

I used that instead of the axle that came with my gran mal. They are pretty damn light.

This is not a 12-10 mm 135 mm step down axle?

hadley does them if i am not mistaken. but wouldn't be surprised if they are steel too, not much material there, outer limit is 10mm, inner limit is a 9mm quick release shaft.

but then again i know that the axles in hopes qr hubs are alu, so might be possible.

sorry, just thinking out loud here.

Holy crap are you kidding...oh man i gotta send them a note

NYC Freeride makes one:

Hey manhattanprjkt83 don't go through I9 for the axle kit. I emailed them and they said it was going to cost $75 to $80 and that didn't included the axle. I was able to find the conversion kit at competitivecyclist for $50. You still have to buy an axle as the I9 kit only changes the hub to allow you to run a 10 or 12mm thru axle. If you need an axle I recommend the Hadley ones and if you want I can let you know of another place online that has those for a decent cost.

o rly? do share.

im pretty sure there isnt a human that can ride a bike thru a rock garden and tell a difference between a 12mm and 10mm axle. who cares. go with 10 so you have more wheel options.
