Hi,

Can anyone explain to me what are the differences between the ST and
the X that make the latter better and more expensive?

The X has 24 gears, Maxxis Hookworm tyres and a 24'' (alloy rim) wheel
on the back, while the ST has 7 gears, KMX tyres and a 20'' back
(Nylon Mag) wheel.

This are the obvious differences I found. Besides the gears, what
makes the X better? Its wheels are more fragile than the ST's, right?
And they must be the same weight because both models weight 19.5 Kg...

So why is the X more expensive? Does the bigger back wheel offer some
advantage? Why doesn't the X come with mag wheels too? What's the plus
on the alloy rim?

I haven't yet seen (let alone ridden!) an X up close.

Cheers,

Ana
