Yep.

flat side to the outside, links facing backwards on the lower run (grind resistant they say).

Cheers Bud,

So there's another reason why it sounds like a bag of spanners in a washing machine  :2funny:

Soak a paper towel in WD or GT85 and run it along the chain every once in a while, keeps it clean and adds a hint of lube. All you need to do  :daumenhoch:

I've been slapping red Teflon grease everywhere this morning...........  :coolsmiley: the bikes hardly been used so I've stripped and cleaned it over the weekend I had the chain soaking in WD40 and gave it a rub over with a nylon brush as well  :daumenhoch:

Think the cranks been over tightened or something because the bearings are not the smoothest also I think the front sprocket is a bit thin there's a decent gap when the teeth engage the chain links

I've got a new sprocket and cranks coming soon so I can have a good fiddle then

I can highly recommend the Red Teflon Grease (TF2 Lubricant) bloody good stuff   :daumenhoch:








I can slide a Heinz baked bean tin up my chocolate starfish now and it doesn’t even bring a tear to me eye  :daumenhoch:

this works and also make sure they arent too tight and they are aligned right .i have had some really noisy half link chains for some reason or another usually too tight or misaligned a tad

Some of the Shadow halflinks were rattly old things.

Peter - have a look inside your BB - is the spacer tube in there? That's the main reason for BB bearings fcuking up, spacer missing. You tighten the crank up and crush the inner races toward each other.

If that's all ok though, you can pop the bearings out, pick out the seals with summat very small and pointy. Clean & soak them in petrol or similar and then repack with your nice red grease and snap the seals back in. 9 times out of 10 the bearings will come right back to life.

Yep checked the spacer was there when I cleaned/regreased everything  :daumenhoch:

I've only "nipped" the crank arms up and used the little caphead screw to tighten the crank arms up

Do the bearings come out that easy  ??? I thought it would be a hammer and drift job  ???

You should have to tw@t bearings out - if they're loose then = trouble :)

They are a press fit.

Without insulting your intelligence, that means they are lightly walloped out or in.

Interference fit would require a bearing press or significantly more aggressive hammering - think oldschool headset & BB cups.

They'll only need a light tap with a hammer and a nice weighty drift of some sort.

My half link rattles like fook, the noise of the cassette hub drowns it out once on the move though...  >:D

Mine sounds the same so I must have set it up right  :daumenhoch:

I'd even put an inclinometer on it to check......you can tell its not british engineered  :Great_Britain:

Half link chains are generally noisier than standard chains,avoid if possible :daumenhoch:

No but It looks like the bike is the wrong way around? :D

Not sure about the bike or chain being backwards but the rider is definitely backwards....... Some would say he was "special". He is from Derbyshire though and they're all famous for webbed fingers and toes and love shoving stuff up  their ringo stars. Wierd really....
