Just wondering, is it really a large improvement over the regular Qr? Anyhow Thanks :cool:

Two factors.

Yes.

First, the 20mm interface is much beefier in several ways because of size, contact area, and bolts (usually). Secondly, most of the forks that come with 20mm axles are usually built stronger also. Some manufacturers do make almost identical forks with QR or 20mm, but most have some significant differences. There is definitely a more positive steering precision in rough terrain with 20mm front axles in just about all cases.

How about the new crop of forks? AM1, Shermans etc with QR and 150mm travel (and 32mm stanctions), do they compare for rigidity with prev gen ~130mm thru-axle forks?
Yes, even the new generation forks benefit from having a 20mm axle. A mate had the QR Nixons and said they were awesome...didnt need a thru axle, then he tried the 20mm and said he was wrong. This guy works for a bike comp wholesaler and rides alot of new stuff.

SMT hit it when he said, once you've tried it you wont go back. I have 20mm set up on my trail bike as well as my DH.

if i have QR and i buy a fork with 20 mm do i get a new wheel set or hub?
I think that you gonna be better off buying a new front wheel ...but if you like your rim you may get a 20mm hub for cheap and put it on that rim.. It may end up costing you more money...go for a new fron wheel.

it depends, when you move to a dual-crown fork...it doesn't make as much difference IMO, especially when you put a BMX-bolt-on axle in your hub (if it can accept it). 20mm is nice, and for all downhill oriented stuff it makes sense to just make it all 20mm so it's all "standard", but for some applications it's not critical, a good solid bolt-on axle can make a big difference too.

I have a P2 that came with both ends 10mm nutted axle (which I thought was good for jumping).

I know the rear end has to be stronger, but I was wondering how the front was comparable to a 20mm thru axle in regards to flexing and steering inputs.

I just upgraded the fork and stayed with a standard dropout.
Hope it was a good choice.

Can you buy cheap and or expensive front and rear aftermarket 10mm nutted axle hubs?
I might want to have a lighter set of wheels built.

Any info would be helpful.......thanks
