hi people, i don't know much about bikes but got one lastnight..
but while riding it home i noticed the chain kept slipping, would pedal fine, but when i stopped pedalling then started again the chain wasn't doing anything, it was dark so i couldn't reallly see what was going on, i guess i need to adjust something
also the front brake is stiff, the disc brake only just fitted inbetween the pads, someone said something about brake being pulled without the wheel on?
thanks.

OK for the brake its easy,
pop the wheel out, and you can use a flat bladed screw driver with some kitchen paper over it, slide this between the pads and push them back into the pistons gently, should solve that!
As for the slipping best wait for NIc, if you could give some more details if the chain is slipping on the cogs or what, as it could be the free wheel, or normal groupset wear0 -
thanks for that, will try that tonight
i'm not sure whats going on with the chains, sounds a bit creeky too, when i bought it the rear derilla bit wasn't fixed on, i had to bolt that on.
i couldn't tell where it was slipping, hopefully i can give more detail tonight when i get home from work.
cheers0 -
yeh post a picture if you can Nic likes that0
-
btw are you at newport in essex or wales?0
-
wales, bout 10-15 minutes from cwm carn, heading up there tonight.0
-
are there any type of guides or explanations or how all the gears work, and the brakes, i really am lost, i don't even know what the gear shifters do yet...which way is up a gear (faster, more effort) and which is slower0

Oh... and have a read of ParkTools... Nic likes that as well

thats a brilliant link!!
very useful to me, like i say a real beginner0 -
right, i have been tinkering and i found that the problem is i can't pedal backward or free wheel, the chain kinda bunching up and the rear derilla thing bends with the chain.
if i slacken off the quick release thing on the wheel hub its ok, but wheel will fall off
i can only put it down to this bit, which is stiff to turn while your holding the gears

Sounds like the freehub mechanism has died.0
-
i just looked at a guide on the hope site about rebuilding it, could it be the bearing are knackered, or would it be because the bike has just sat in a garage for a while?0
-
What is the hub? Yes, Hope can be rebuilt - may need new bearings though.0
-
what do you mean what is the hub, its a hope hub but not sure on model.
from reading more stuff online it sounds like it could be a cassette, something to do with freewheeling? is that part of the hub? what type would i have? its just too stiff when you tighten the wheel up, is fine with quick release lever left slack but the wheel could wobble about or even fall off, so daren't ride it0 -
What model hub? Once you know that, you can download the correct guide to stripping the hub.
The cassette slides on the the freehub mechanism (on hope called a rotor body) which contains the pawls and clutch mechanism for the 'freewheel', and a set (or usually 2) cartridge bearings. You need to remove the cassette, the rotor body and service it, maybe replacing bearings. The bearings have no adjustment as they are radial cartidge bearings which press fit.0 -
the hub is a hope XC, its strange that it only does it when wheel it tight, i really can't figure it out, everything feels smooth and fine until you tighten wheel up0
-
i now understand stand what is meant by the free hub, it seems this is my problem
really gutted, was hoping to be out on bike by now, but looks like i need someone to fix it0 -
They are straight forward (ish!) to strip, just have to keep an eye on the order of all the parts!0
-
is it common for this to break, the bike isn't that old and hardly used? seems to work fine when wheel is off bike, works fine with wheel on, but as you tighten the wheel to the frame the cogs get stiffer then won't turn?
how do i know what to order etc and where from? i guess i need tools too.....lol this is going to be another expensive hobby i can see0 -
It's hard to say - but I'd always start with a complete strip down and service. If in doubt, contact Hope, they have good customer service.0

update time
ordered all the tools on internet last night, couldn't wait so got up this morning and went to bike shop and bought them there. So i know have two sets lol
took wheel with me, bloke in shop said it felt alright, i mentioned it only happened when i tightened wheel up and he said he had the same thing with his hope hubs after taking them apart and missing a spacer out when he put them back together.
got home and started taken bits apart and only got this far but this rachet seems buggered!!! the springs were chewed up and all over the place, here's a pic, i stopped taking it apart now until i know what i'm looking at in the hub part, going to fetch the diagram in a min
i circled the pawls and springs0 -
You can order fresh springs and pawls - infact Hope recommend you change them with each service. Definitely a mess in there! Needs a very good clean, the new parts, and fresh grease. Check the cartridge bearings are smooth too - just spin them.0
-
none of it feels smooth now, i think i need a new freehub with all the bits inside it and the springs, pawls, and also the hub bit of wheel rebuilt with new bearings and seals etc
just gotta find someone to do it, i had a go at getting bearings out of the freehub and they were stuck solid, same as the ones on hub where you hit the shaft0 -
I am also a relative novice on bike mechanics (sorry).
On my Specialized Roubaix DI2 I removed the rear wheel (for practice). When I replaced it all seemed fine, until I realised that it will now not freewheel. What am I doing wrong??
Thank you !

Congratulations on reviving a thread that is more than ten years old!
As a recent new member, it took me a while too to get into the habit of checking that date of the post I was responding to, so don't fret yourself.
I am not familiar with that particular bike (or even road bikes, full stop!), but I'd remove the rear wheel again and replace it once more taking particular care to check that the axle is in the correct place in the dropouts on both sides, that the skewer or axle is not too tight. Anything else would require me to be more specific than I have knowledge of the bike - so I'll stop there.
I must say that that your reported fault has never happened to me, and I've had several freewheels fail on me. But they usually just stop driving or maybe become intermittent first before failing totally.0
