tiptop Posted June 18, 2012 Report Share Posted June 18, 2012 Just bought a Zhi 20" and the crank arms have a bit off movment on them i think this is due to the spindle in the BB being wore as i tryed the arms on another bracket and ther fine so im just wondering will most BB's for a 20" trials bike fit mine and let me bolt my arms on? IE the one in this ebay link http://www.ebay.co.uk/itm/Onza-Isis-Bottom-Bracket-NEW-BOXED-127mm-68-73-Shell-Includes-Fixing-Bolts-/251086004834?pt=UK_sportsleisure_cycling_bikeparts_SR&hash=item3a75e46262 Quote Link to comment Share on other sites More sharing options...
isitafox Posted June 19, 2012 Report Share Posted June 19, 2012 That will probably work fine but it depends on whether you've got ISIS or square taper cranks Quote Link to comment Share on other sites More sharing options...
