Langster sprocket removal

Craggers

Hi,

Anyone know if the rear sprocket on an '09 Langster (OE,unbranded hub) has a standard or left hand thread?? I've got the lockring off which was left hand thread so I fear I already have my answer, but the actual sprocket thread seems much tighter and I don't wanna brute force it the wrong way.

Cheers

I would assume the sprocket tightened/undone the same as any other fixed hub as you'd undo the sprocket with your pedalling action.

So is every other fixed hub left hand thread or standard??? I would have thought that if it was standard then forward pedalling action would tighten and rearward action would loosen or am I (as usual) wrong???

The thread is a normal RH thread. Tighty righty, leftie loosie. Though this has now got me thinking. Think a visit to Sheldon Brown might be worth a read.

That's right. That's why your sprocket's so tight, it's been tightened by all the riding you've done on it.

Lockrings are reverse threaded so that if the sprocket comes loose (on the track, with no brakes, this is how the bikes are slowed down, so it's important) and tries to come off the hub, it will tighten the lockring, keeping it tightly in place.
