Newbie BMX Questions

[Takingabreak]

Hi,

I'm looking for some help regarding a BMX I picked up for my Daughter.

It's a Redline RL240 from late 90's (I think)

I've a question about cranks and bottom brackets, I've yet to strip it down bit it looks to have threaded cups and a crank that passes through the bottom bracket shell. The thing is, it's quite a long crank. Are short cranks available for short people? I've spotted a square taper crank from Sinz that looks ideal but can't see that a square taper bottom bracket will fit the shell. I've not measured the BB shell but it looks oversized compared to a normal bb shell.

Any experts out there to point me in the right direction / correct my thinking?

the 90's rl240 has an american bottom bracket (was the std bmx size for 20+ years) which consists of two cups which push into the frame

you can get shorter crank arms

thanks Kev-s much appreciated.

Another Newbie question if I can..

How does the chain ring come off the crank?

 

[kev-s]

the chainring is attached to the crank via a locknut which also acts as a cone for the bearing, generally u need a big pair of grips to remove the lock nut

Thanks again, I reckon I'm ready to go.

Daughter wants it stripped down and painted pink, she doesn't like these colours.

Or shouldn't I say that around these parts...

Regarding the BB cups I assume I'll be able to drift them out?
