hi there! i need some bottom bracket experience.
its the first time im changing it myself so be gentle :)
so this is my beater, '98 trek 6000. bottom bracket died so i removed it. its a 68x122.5 (VP is the brand btw). heres the thing.. when i went into a shop a guy by looking at the bike told me the one i needed is a 73x122.5. so now when i removed the one it had installed.. i measure the width of the bottom bracket cage. and its 73-74mm. so i supose the bikeshop dude was right and i had installed a shorter bottom bracket.
is this right or is there another way to choose the correct width of the bottom bracket shell?
also if i swap from a 68 to a 73mm width, will the position of the cranks be different? (slightly wider or something?) or do they remain the same as long its still a 122.5 ?
any prob if i go again with a 68mm? could i fugg something up?
thanks and sorry for my crap english! anything else i should know about bottom brackets before i go and buy the replacement is great, thanks!
