Hi all. I have inherited (from my son in law)
mountain bike. I believe the cycle may have originated from Halfords and is possibly not a top or expensive model. Since he is a bit of a heavyweight and apt to favour, when riding, brute force over technique or style the cycle’s BB ist kuput. I was surprised to see that the BB is what I would consider of dated construction as it is not like those I have seen with a sealed unit and retaining nuts that need a special socket to remove. Maybe it is just because it is a little long in the tooth like me.
Anyhoo I have stripped the BB of crank arms, peddles, gears... and locking ring leaving just the crank axle and bearing assembly. I have been unable to shift either of the “nuts” that retain the crank axle/spindle either side of the bottom bracket with any of my extensive range of spanners/adjustables – there is just not enough nut depth to get a purchase.
My next step is to clamp the nut (bike and all) in a vice but before I do, I wanted to check the hand of the nuts. I understand that normally for UK/USA ... bikes the left hand side (non-drive gear side) is normally an ACW unscrew thread, and the right hand (Drive sprocket side) is a left hand thread, which requires a CW turn to unscrew. However, for France this is not the case. I am not sure if the Apollo is a French manufacture or not & so I am unclear of the hand of the nuts.
So can anyone confirm the thread directions?
Cheers
Ray
