will dex 210 front wheels fit a associated b4
 

i was wondering to know if the dex 210 front wheels fit the b4 as im unsure about the bearing size

i have a feeling the associated axles are smaller so probably not. may well be wrong though

one metric, the other is imperial so prolly not

Associated wheels don't fit the DEX210, so its unlikely to work the other way round. You can get different front axles for the 210 to allow the use of B4 wheels instead of Durango ones, but I've not heard of anyone doing the same the other way round.
