Does anyone know the axel size of a redline proline crank

[BMXBEN]

Please so i can buy replacement bearings

[RATTY]

Ben, just checkin, is it pro lines or flites you have?

[MartyC]

Tone, think they are Pro-Lines he has - got them of  Motomag2

[RATTY]

So they are bigger than flites which are 19mm, sorry cant help any further

[MartyC]

I'm pretty sure they are a 20mm diameter, so a standard Odyssey one should fit    If it's just the bearings that are shot then there should be a number on the seal that you can take to a bearing shop and a 141 replacement 

[darkersomeday]

have a look at the 400 series in ratty's thread, i'm fairly sure theyre 20mm,

if you need a spare i've got one here if its any good,

[BMXBEN]

Cheers lads the bearing casings have been fitted with a hammer & there shot to bits & one of the bearings is crap too. I put an engineers ruler across the centre hole & it says 21mm. they are redline prolines i got off motomag

Ben, I had a similar problem with one of my BB's, I got my mate to put them on a lathe and skim the outer surface then I wnet to work with wet and dry before polishing them - the outers look like new now although the insides are not so pretty but no-one sees those when they are on.

BTW, on your bearings is there a very thin top-hat style washer pressed in?

Hi cant see any top hat washer pressed in although im not entirley sure what your on about. i could probably get away with new bearing cups but again i dont know what size one's to get

[theRuler]

they are 20's

i have some 20mm bearings for euro cups (no cups though) that will fit them, if you are gonna run a euro BB

alans sells 20mm bearings that allow you to use them in a spanish bb
