Is there any major difference between the Nimbus II and the Nimbus X? If so, what is it?
One’s silver and one is black:D
Nimbus II frame has clearance for a 2.5 trails tyres, it would be harder to fit in the nimbus x frame

Different number of spokes too (though it doesn’t make a difference really)
i just got a nimbus X and it came with 114mm crank arms… i like it although im afraid to do too many hops and jumps with it… so im getting a kh 20 trials uni soon… i got a 28"sun recently and it seems that im riding that alot more then the ol 20" its alot faster and lots more fun, i just got the nimbus X and im thinking of selling it, since i dont ride it much.
ok so i am selling it $120 + shipping let me know if you are interested. look in the trading post section for pics.
ive seen a thread like this before 
im still waiting for a email back from uni.com…3 days waiting now.
i got my answer…
“The only difference is the width of the frame. The Nimbus X frame is wider than the Nimbus II frame. The pictures are not ready for posting yet. Thanks!”
Is it just me or does anyone think that the Nimbus II/X frame’s are pretty ugly.
I’ve got a Nimbus Trials and I’m thinking of buying a new frame because I dislike it so much.

The X makes it sound cool.
I recently bought the Nimbus X and it does not have 127 cranks it has 114s and does not have the Hookworm tire
I will say I love it! It is a VERY nice Uni
I just noticed you where asking about the 24" model the one I bought was the 20" version sorry
the 20" Nimbus X seems to have flat tops and the 24" Nimbus X seems to be very similar to the Nimbus II. Not sure why but take a look
