the bb is as tight as it will go and it still clunks when the bike isnt moving at all. Thanks anyway Swift

Took my back wheel out and put spacers in the back wheel so now the chain is straight but the clunk is still there we have put it down to a bearing in the back wheel does anyone know how to go about replacing them. Thanks Swift

Ok thanks, We've taken the spacer out of the bb and really put some pain on while tightening up the arms and it now seems to be running more inline. I think that could possibly be the problem, the shell (i take it that is the part of the frame where the bb goes) is 68mm and there was something on the bb about 68mm and 73mm with spacer/without spacer. Don't fancy trying to get the arms off again, without the proper tool. I'll give Rock N Roll a ring tomorrow and see what they say. Thanks for all your help

yeah both having a centered tooth sprocket and turning the current one around would make it worse and the bb is what rock 'n' roll bikes said we needed.

A 127mm onza isis bb and and an onza 12t rear sprocket. We got all our parts from rock 'n' roll bikes and these parts are what they told us we needed.

The thing is the front freewheel is to far out from the rear sprocket causing a slight bend in the chain making it clunk. Does anyone have any good ways of removing a freewheel without damaging it.

If i do that it will make the wheel be out of center in the frame also before i took the photos we had a spacer which was supplied with the bottom braket we removed that to try and get it more inline. Finaly how do you know when the bottom bracket is tight enough and not to tight?

Hope these pictures help let me know if you kneed any more.

We had a look at the chain line and at the rear wheel the chain was bending out away from the wheel just before the sprocket so should the freewheel have a spacer inbetween it and the bashring? Thanks Swift

Just got a better look at my bike and it turns out that the clunk is coming from the back wheel any ideas? Thanks Swift

Thanks for all your help i will try that tonight and ill let you know if it helped Thanks aganin Swift

Im using chain tugs and a tensile 60click My crank arms are about 8mm of the frame and i hope the bb is ok as its an isis one

Bought an onza t-pro a while ago with no crank and just got round to buying a crankset, the first proper ride a had out on it i noticed whenever i go up a hill it clunks does anyone know what is rong with it. Thanks Swift also it makes the same clunk when i land a backwhel hop

I'm new to trials and i didn't understand the term chain wrap and the top of the chain when pushed down is about 5 mm off the chainstay also i have a 12tooth rear sprocket

yes and no were ive been riding there is good steps, walls ect but they are all to advanced at the mo really

Whenever u go up a slope really and i doubt that anything is skipping as ive only had the crankset chain and sprocket for less than a week and it is front freewheel if that helps any.

Hi, when i push my right pedal down when pedalin along something makes a big clunk has any one got any ideas as what i could be???? Thanks Swift

thanks i was worried when it stretched last night lol

hi just recently got a new crank set and the chain appears to be stretching is this normally with a new chain??? Thanks swift

Do you know what year the onza rip you are ralking about is?

Thanks for that sam i ordered my parts from rock 'n' roll bikes i hope there ok Thanks Swift

Hi, Found some parts on trials - UK and wondered if they were a reliable website any advice about them would help Thanks Swift

Tarty bikes have the exact crank set so i should think that they will have the right arm only but i'll have a look. Thanks Swift

Thanks for all your help i think you have managed to change my mind back to wanting a front freewheel after all i would just ending upgrading to a front freewheel if i did get a rear freewheel. Thanks again Swift Just had a look on ebay and wondered if these cranks were worth buying for my bike??? Tensil Crank"]Tensile Crank Thanks Swift Them cranks are the cheapest ive seen yet i shall be looking into the site for my other trials parts at a later date. Thanks for the help Swift

It is quite cool to look at but i would'nt know what it will be like to ride and i would have a go on his bike when he gets the new frame but he dosn't get it untill christmas. also at one point he was thinking of getting a because frame from tarty is was around £200 pound i think
