just reverse the direction for whatever suits ,gets it good and tight (much tighter than a chain whip could )and then just nip the lock ring up:thumbsup:

well the cog would only come loose really with a lot of pressure (ie skidding or heavy leg braking a lot )but in the real world not really ,its just another thing that would give u peace of mind ,(a tightened lockring ) but in reality i cycle with a few guys with fixed gear sprockets .and NONE of them use a lockring ,they just rotafix and its solid

Technical point: single front brake is only legal with a lock-ring fitted (not that anyone's likely to notice, except possibly in the event of an accident).
42x16 sounds about right, should teach you to pedal rather than grind a gear.

yer but once you learn to peddle, I guarantee you will want to up the inches! 42 x 16 is quite spinny.

I'm quite happy on 43x17 or 43x18. Have been for several thousand miles a year for more than 30yrs. Never yet found myself unable to stay with a bunch for want of a higher gear. There's a lot of misinformation peddled about pedalling cadences.

[QUOTE 2234060, member: 1314"]I had real probs with the chain, though. First time I've used a chain tool - Parkers. I could split the chain and leave the pin in the hole as instructed, but I just could not get the pin back in and join the chain. I tried for 2 hours on various links - I practised on the old chain. In the end I realised it had to be a bike shop job. I'll have to do more practising, I think.

Now...putting a chain back together (yes I saw all the videos but just couldn't do it!) Hints and tips be great![/quote]

If your chain is like this:

...you need to push the pin all the way out and then put the joining link (on the left in the photo) in the hole. Don't think anyone re-uses pins nowadays (well, when I say anyone, I mean me really:smile:). Links like the one pictured and various others are much, much easier to fit.

This video (from about 5'10" to 7'10") shows someone fitting the above type of a chain to a motorbike, but the principle's the same:
