New school BB 1pc to 3pc tech question - 2011 Haro jr race bmx - cranks too long

<< < (2/2)

Jon The Bassist:
The description looks wrong - the crank length seems iffy, I'd double-check before you buy. Also the chainwheel looks fixed so you'd have to throw it if it wore out. I got my lad a decent 'Lasco' 3 piece square taper crank for only a few quid. Good on you for addressing the high gear and long cranks BTW, a lot of completes have been sold like that - I wonder if it's a US preference?

Gary72:
If it already has a square taper axle and sealed bearings, You should be able to leave that as is and just replace the arms. Keep the longer arms for when she grows. If you get something like the Sinz cranks as shown above the chainring can easily be changed aswell. Might be worth having a mooch(someone used this word on here awhile ago and I seem to have adopted it) over on BMXTALK as it is more race based and people are always upgrading and selling kids stuff.  :daumenhoch:
