im currently riding a torker dx and want to put a new frame on i like the look of the nimbus ll as i can get in some jazzy colours but i also bash my shin on my flat top frame at the moment so the round top is also an option i have heard that the round top is stronger what do you people think i should get or should i just stick with the torker frame>>
You bash your knees/legs significantly less with Even the Nimbus II frame compared to the DX frame. If you think you are going to do any sort of flatland you should get the Nimbus II. If you are a strictly trials rider or a street rider who has no interest on foot on crown tricks then go round. Stuff like gliding and certain one footed tricks are still possible on rounds, its just a bit trickier.
The round crown nimbus will fit better as well. You would need bearing shims if you were to get the Nimbus II because as far as I know, all the Nimbus II frames UDC US has are made for 42mm bearings whereas their Nimbus Round frames are made for 40mm bearings which the DX uses.
