My sons 2010 Redline flight has a problem, the rear drive has gone !!! how do you get the cog off to get to the Pawls to service them, I suspect that they have frozen ? he has a training session in the morning weather permitting (bikes only 2 months old) do I need a chain wrench or something?
Thanks in advance

If its a cassette hub you'll need a chain whip and the tool with the correct amount of splines to undo the lock nut.
This might help mate.

Cant say for sure as Ive never worked on one them but it looks like you just need a wrench big enough for the flats and a chain whip.

If you believe the pawls are frozen just take the wheel indoors and heat the hub with a hairdrier and keep rotating cog back and forth until you hear it begin to click again. If that doesnt work then it may be something more sinister and you will need to strip it down.
To remove the cog you will need a chain whip and 36mm spanner I believe. Removing the cassette is the unknown as I haven't worked on redline hubs. I would have a guess that you will need to remove cone nuts from axle and then using a rubber mallet knock the axle through to push the cassette of the other side.
With the likes of Profile hubs once the axle spacers are off the cassette just slides off. I dont think this will be a simple. If you are still having trouble post up some pics of the hub and will see what we can work out.

^ yep I agree with this. I normally just need those tools to swap cogs out but to actually get inside to work on pawls etc. Not sure.. Good luck tho!

Thanks kuwahero, I did get it working yesterday by flicking it back and forth but he has rung me today to say its stopped again, will look when I get home, have spoke to Chain Reaction Cycles and they want me to send the wheel back ! we have a meeting on the 9th Jan so can't risk it.

Kuwahero has it right.I have a Flight cassette hub and you just need a big enough spanner .If narrow enough you can loosen the lockring (turn anti-clockwise) while it`s still on the bike and keep pressure on the pedal to stop the chain turning backwards,so no need for a chainwhip.Ideally try a squirt or 2 of GT85 before you strip it down.

Thanks guys, got some heat on it and all seem fine, he must have got it soaked when he cleaned it after the last race and it froze in the shed, should hold up for tomorrow or it could be a comedy moment resulting in a crash
