my knowledge of DJ bikes is limited...

if a DJ bike has a 3 piece crankset can I fit a shimano hollowtec crank to it and a shimano BB?

    Maybe. Maybe not.

    It depends and yes and yes with a converter.

    You are going to have to be a bit more specific.

    the problem is im not 100% on the frame yet

    what are the BB standards generally used on DJ bikes, are they similar to MTB? Like I said my knowledge is very limited

    MTB or BMX and others. (Spanish, mid, and others)

    Post pics or more info. Threaded or......

    Ok from the info on Saracens web page No CX but CR2 and CR3 and AL

    One of them States a MID type BB which is a push fit bearing no cups. The others don't really say.

    But at a guess not threaded.

    my bad it is a amplitude cr

    okay so I'll work on the basis its a push fit, thanks for that!

    So working on a mid size BB, what does this mean for a crankset? will it need to be a mid specific one?

    Just swap out the bearings. Or buy another Mid crankset.

    But what are you really trying to do? And take the thing to bits and see what it actually is.

    I essentially want to know if I can fit my XT cranks to it

    Nope.

    But again this is assuming that it is MID or Spanish or whatever.

    MID.

    Okay how can I check when I have the frame? or could you tell me if I posted a photo?

    A photo and some measurements would do it. If it is a mid bb you would be better off with bmx cranks (profile or the likes)

    Okay its a press fit and im fairly sure it is MID

    the bearing in at the moment has the code ISK R12-2RS

    So is this for a 19mm spindle?
