Gears skipping at random

[Super Sywurm]

I understand the logic to this but it's an expensive way to possibly find out that it's something else?

 

Luckily, my lbs would lend me a cassette and some parts untill we find the problem.

 

Dis net moer baie moeite om elke dag die fiets in te vat.

I don't see a clutch derailleur solving the problem it only controls your chain slack better. This is cable tension related.

how do you come to this conclusion? the OP has not said what bike it is, whether he has a closed cable system or if the system is running smoothly when not riding over rough terrain, you may be right but to make this assumption off the bat is a little like shooting in the dark through a closed toilet door.

When I'm on the road, the problem is magically gone...

I've been in this industry around 15years and worked for some world class riders/ teams as mechanic so I'm qualified to shoot through closed toilet doors If it is a closed cable system on the bike then it could be quite a few other things- loose freebody/cassette, bent derailleur hanger( but I don't think so as this will be permanent problem), shifter internals damaged, derailleur wheels, very F**d casset, frayed cable, ferules not positioned correctly in frame and shifter. The derailleur could be set to far away from the cassette and so the list grows. But I'd rather shoot through the toilet door as this is a common problem on dual suspensions.

Check that the wheel is properly tightened

Will check this aswell...

I don't have any technical experience, but a worn cassette was my diagnosis.

Oh, well, it only does it when I hit bumps!?

When last were the suspension bearings checked on the frame?

It's purely personal experience, but I've had the same problem on my dual suspension when mating a new chain to a worn cassette. The problem only appeared after replacing the chain and not cassette, and was instantly remedied with a new cassette.

 

Did the skipping gears only start after replacing the chain?

It started with my old chain and old cassette, now I have a new chain with the same cassette.

I don't know, my bike had a minor service last week and the bike is only 5 months old.

See my original solution, send me a 6pack beer when you come right!

Often the problem is the cable loop into the derailleur is too tight, try increasing the loop size to give an easier flow on the cable to stop it catching and hanging up.

[Guest EdEdEd]

When I ride off road over rocks or corrugation, my mtb keeps skipping and shifting gears at random (when I go over bumps in the road). I have a brand new chain on and had the bike at my lbs and they did some adjustments on my rear derailleur, but they did not fix the problem.

 

What to do???

maybe they just feel like dancing!?
