these are the parts i would like to change the reason being the chain keeps slipping and chain comes off every now and then
thanks for getting back to me so quick0 -
It is a spin on freewheel and looks like a basic square taper crankset.
I guess standard threaded fitting but as I can't see that is a guess."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

ok so what can i replace it with any recommendations as i have no clue about the terms that you are using and thanks again for your help
dont know if this helps any or if you would need me to strip it down0 -
That mech is no use off road, it will come off. For, 80 quid youd get something better second hand.0

thanks for that i thought as much i was using it for work but just getting into off road any idea as to what i should look for 80 quid makes models as i have not got a clue what you meant by that mech is no use off road bit of a noob to this0

The whole chainset needs replacing as the rings look riveted on (with fake allen head bolts).
The rear freewheel does not look worn. Infact I would replace the chain and rear mech, and gear cables and see how it fairs.

Or get something new, take a look at Halfords and Decathlons budget models.0 -
i think you are right about the chain set as i have tried to get it off before and they will not budge and the allen key will not go into some of them .
i would like to give the chain and rear mech a go but if it needs a new chainset and it cost 20+ then i think i would be better trying to get a better off road bike second hand or have a look at the halfords and Decathlons
thanks again for your help0 -
What is the most you can afford? As a £200 bike is vastly better off road than a £100 bike.0

If you could stretch to this:

Unheard of to get a gear set like this for this money, workable suspension: bargain.0 -

I have a shed full of useable bits, if you want a good rear mech and chain and even crankset I'll have something you could use, most for a pint plus P&P, PM me if your interested.

Hi there
I replaced the chain and rear mech today but have noticed a wobble in the back gears. i took the wheel off and took out the axle it was bent so replaced that but the gears still wobbles the wheel seem to run true.
i also tightened the gears up as much i could but still they wobble will i need to get a knew set of gears.
Thanks again for your help0 -
Wobble is fine as long as it shifts.I don't do smileys.

Was out yesterday and the gears have been jumping all over the place dosnt happen so much in the middle front and middle 3 rear cogs but still jumps when i put pressure on going up hill i had noticed when i hand crank it there was a stiff link that i have freed off but still it jumps i did notice that the chain dosnt sit well on the rear cogs the barrels will hit the top of the cog rather than fall into the u shape of the cogs every now and then I was wondering if the chain i got a gusset 8 speed 116L 3/32 was ok or could this be the problem
Thanks again for your help0
