Lightweight thru axle - Extralite?

[ms6073]

avoid them, they often cause rotor rub especially in the rear

Um, what? Sorry, you are going to have to explain how an after-market thru-axle can cause disc brake rotor rub.

Now you can pay $80/axle to save 6grams over a J&L unit.

J&L on eBay. Almost as light as Extralite at 1/4 the cost.

Just make sure you get the correct length.

Always nice to see another Army guy online. Any concerns re: weight limit? I am 190 pounds and my bike is nearly 20 pounds. I would love to grab the J&L's but my setup isnt exactly light.

That I can't comment on; I'm 5'6", 143lbs. Thru axles are easy places to save weight, but, not necessarily the best place depending on application. I'm using them on my road bike. If I was 40-50lbs more, I'd probably be more hesitant. I haven't seen any flaws in the construction of the sets I have on my road bike or my wife's gravel bike but those aren't ridden particularly aggressively.

What's the application? Gravel, road?

Asking for help here, unfortunately a very noob question:
I am completely confused by thru axles. I am trying to understand which size should I choose for my Colnago V3RS.
RobertAxle Project website tells me that it is 12mm x 163mm x 1,5 thread for the back and 12mm x 120mm x 1,5 thread for the front.
Is that reliable?

And, simple but crucial question, what would happen if the axle is too long or too short?
Example.: the "real size" would be 165mm. I buy 168mm, do the extra 3mm stick out from the frame with "no damage" and that's it? on the contrary, an axle that is too short would not hold the wheel in place or just leave 2 extra mm that are not covered, but functionality is not compromised?

It is definitely 12mm diameter, so that part is correct:) about the length you can measure it yourself easily, just measure the length of the axle without the head. And as for thread pitch try google how to measure thread pitch. There are instrument for this but even with basic instruments you can make wild guess. But if the length is correct on Robert Axle project web, I would trust it.

I wouldn't buy shorter axle, 1-2mm longer should be ok, will be slightly sticking out of frame.

While the Robert Axle Project product selector should be accurate, are you really going to save that much weight over the stock Colnago alloy thru-axles? While not the same design, hence and apples to oranges comparison, the ones supplied with my Colnago C64 disc are appreciably lighter than the Robert Axle replacements on my wife's Scott Contessa Solace.

I've had good luck with Carbon Ti thru axles and use them across all my bikes - https://www.carbon-ti.com/products/axle ... k-releases

Carbon-Ti has 2 models, Regular has 5mm hex socket, and EVO models, that have 6mm hex sockets, but the price is 3x of J&L.
