my mates is quiet a big lad practically the same size as bigman off here, well so it looks like in video anyway. he bought an onza which he killed - was not put together propely, and he is going to get a new backwheel (19") any suggetsions for really strong hubs? , spokes? ,rims? weight is not a matter at all due to the strenth of the lad,and he doesnt want some stupid amount of money spent on a wheel that aint going to last him, it pratically has to be bomb proof. any ideas ?? thanks ozzy.
