I have one.
I can't really put across what it's like, but I'll try.
Mods feel really small and really really bouncy to me.
Stocks feel slow and high up.
24"s just feel nice.
From what I gather, from a stock rider's point of view, I think it's very like a stock, only it's faster responding.
She first came up on 4chan when she made a video, in which she seems to be quite strange, and it was posted in a 'you rage you lose' thread.
Half of them hated her, half of them loved her, chaos happened, I think moot turned /b/ off because of it.
What to do -
Make a screenshot of your current desktop.
Paste that in paint. Hopefully then it will resize the document size to be your desktop size.
Cover the screenshot in your collage of pictures.
Save it.
Set it to background.
In the case of freewheels and freehubs and what have you, getting a good one also improves the amount of EPs, which can also improve your riding. For this reason it's pretty useful.
Now for the OP... If you want a new hub, you might actually want to pick up a pro 2 t from the for sale section on here.
