400 for dem pikes be bargain!
My headset bearing came the day after i ordered it from mb bearings. It looked slightly different to the one that come out but all the contact points were the same along with measurements just a different level of machining to the 45 degree outer case which sits in the headset cup.
I couldnt resist trying it as i was worried of the fit. Getting it in the headset cup was very hard compared to the last bearing probably due to the bike being freezing so the cup would have slightly shrunk being outside in 2 degree weather while the bearing was in a 20 degree house! It went in a little wonky so i though i'd tap it back out and start again. When i looked through the top of the headtube all i could see was the tiniest bit of bearing i could tap out, so i tried with a little carpentry hammer and flat head and to my suprise/amazement i managed to knock out the inner sealed bearing body leaving the actual balls and outer bearing in the frame AHHH GREAT, how the foot am i going to get the rest out? Even if i do how the hell am i going to put the bearing back together if i get it out? So after 30 minutes of sweaty fumbling with the bearing somehow the inner bearing went back in and in the process straightened the bearing out and all went back perfect.
moral of the story, get an acros, hope or king headset instead of cheap cruderknacker
