2002 haro shredder lhs bottom bracket needed.
cozi70:
Hello folks.
I've got a 2002 haro shredder lhs crank bike.
Problem is I need a new bottom bracket as one off the inner bearing threaded parts is damaged.
It's a three piece crank,centre bit being 150mm long and its got very similar BB to the one piece type apart from the 2 inner bearing threaded parts are threaded the wrong way,meaning the Lh thread is where the RH thread should be and vice versa.
Here's some specs
Any help would be greatly appreciated as most off my local bike shops are not interested in helping out with bmx's.

Anyone?

Looks like a standard american bottom bracket set up. If your axle is ok what fits to the cranks, then pop into a bike shop with the axle and ask for an american bottom bracket and test fit the cones what go on the axle. If the fit, then jobs a good un. Use plenty of lithium high melting point grease.

I'd be tempted to ditch the lot for some better cranks with a sealed BB

Yep - you'll be hard pushed to find replacement threaded cones for a caged-ball LHD crank. Do what Pickle says and splash some cash on a secondhand pair of Profiles or (dare I say it) Redlines. You can pick em up on eBay for around the £50 mark with bottom bracket.
Only problem is is you want em LHD. You can get em, but they'll be more expensive than the RHD counterparts - just get a RHD pair, flip em and then swap your pedal cages over.
