Answering your cycling questions

you can run pegs, and it is a 14mm.

Yes, it is 14mm and you can run this with pegs.

Yes it can, and yes it is

Yes, you can run pegs on this hub. And yes, this has a hollow 14mm axle aswell.
( I used to run these same hubs and they run really well.)

Hope this helps.

Sorry but you can not.

unfortunately not, no you can't.

There are no titanium upgrades for this hub at this time

the current specs are
CNC 7075 shell. Forged and heat-treated axle. Ceramic driver bearing, SKF 6902 axle bearings, 36h, 9t as standard. Left hand drive (LHD) and right hand drive (RHD). Weight: 369 grams/ 13oz

Yes, it will fit your bike. This hub is pretty loud but this is what you want on the BMX.

It is ok to use on any bmx, but i cannot confirm how loud the hub is

With the female axle the bolt threads inside the hub and the male axle the nut threads onto the axle

both models with fit your frame

Hi there, generally, female axles tend to be stronger, and if you wear down your nuts, you can simply replace them, that tends to be the general idea of a female hub. Male hubs tend to be slightly heavier with a one piece axle. Because their lighter, they tend not be as strong.

And this will also fit on your mongoose chamber perfectly fine.

Hope this helps.

This depends on the rim and lacing type. There is a special calculator here:

Just follow the steps.
Hope this helps.

Depends on what rim you are building it on to

Hub flanges vary on different hubs as do rims so there is never a standard size spoke
