bottom bracket confusion... help :)
mattuk:
if it is one on them where the hell do i get one from :O just look ey has nothing apart from importing from amercia at around £35+
if thats case im just selling the haro cranks and buying a new chrome crankset that comes with BB already on
now ive ordered a 22m BB that should be here today/tomorrow.... would the original bearing that came with the axle (guessing now theri 20mm) would they fit inside the 22mm BB's cups ? cause that could work?
they never went in the other cups thats all even after sanding
HEYWOOD BMX:
:) Gussett and D20 both do 20mm BBs (D20 are cheaper) Alans and Custom Riders sell them.Wait until you get your new BB and see if it fits.Haro/Fusion did make cranks with 20mm axles for years... :daumenhoch:
fugazi:
You're having a right old time with this :LolLolLolLol: as said they'll more than likely be 20mm then as i don't think Fusion did 22mm. Gusset and Fishbone also used a 20mm b/b for years if that helps :daumenhoch:
mattuk:
gotta try and see the funny side i guess.... im hoping i can get the bearing that came with the crank and definitely fit it will pop into the new bearing cups
i'll get searching for a 20mm bottom bracket just in case
although im seriously thinking to ebay the haro fusion crank and invest in a nice second hand profile one or something and pay the extra $$$
anyone got one for sale or even just a nice chrome 3 piece WITH A BB THAT FITS :P
TwoBobRob:
Just to iron this out a bit for you fellas...
A proper US BB is not metric. The axle is actually 3/4" (19.05mm), so near as dammit and causes no problems. However, some companies have everything made in Taiwan and/or China (all metric), and have taken over the years to using some oddball sizes for things.
Stick to what you know, traditional stuff, and you'll be fine. A good ole US BB will suit Profiles or Flights no worries. That DiamondBack BB is fine for the job.
