Derailer (spelling) allignment

jane82

Im stuck with gear 6-10. When the bike is upside down it changes fine but the right way I cant seem to get the big cog switching.
Would it be expensive to get a shop to set it. Im aware its a matter of getting the two screws right I just cant seem to get it. Ive watched all the youtube videos no joy.

Should only be a tenner for lbs to sort out. Any more being your business elsewhere. It might be a cable tension issue and not the limits. Maybe it's too tight.

You don't need to adjust your spelling, "derailer" is correct English according to Sheldon.

Or dérailleur if you can be bothered to fada your rothar.

If everything is switching fine upside down it's not the limit screws as they have nothing that would be affected by being upside down as the only set how much travel is allowed on the deraileur. what do you mean you have 6-10? you can't access the first 5 cogs when it's right side up?!? is it the biggest or smallest cogs you can access? I presume you're talking about the rear gears?

Its the big cog on the bike.
I can put the chain manually on any cog. It doesnt change by switch.
I put it on the middle for obvious reasons.Gears 1-5 or 10-15 would be kind of impossible to stick with ll day.
So front derailer, the cog that spins with the pedals not the back wheel.
I was thinking it worked upside down because the chain hung a different way.
They are shift type gear leavers. If you turn them upwards and hold they should change up. Downwards and hold they change down.( Bit silly really for a 3 gear cog) .

I think I get you now, I find your descriptions a bit confusing! I think by 1-5/ 10-15 you mean when its in the smallest cog(called a ring) on the front on the biggest ring on the front, respectively?

Normally, if talking about the cogs on the front, they are called chain rings which are attached to the cranks which are pushed by the pedals. If you talk about the cogs on the back, it's the cassette.
To talk about the chainrings on the front, you would never describe them as a speed or 1-5 etc., just big, middle or small.

"By switch" I presume you mean the controls on the handle bar? These are normally called shifters. So, when using the shifters, which chain rings can you get the chain to move onto? Just the small and middle ones? If this is the case, where the gear cable is going into the shifter, it should go via a little barrel adjuster. If you rotate that, it should make enough of a difference to get you into all chain rings. I'm still not quite sure what you problem is. Is the problem you can't get it into one of the chain rings but can get it into the other two? Is it a racer or a mountain bike?

If you've watched a few of the youtube videos, they should use some of the terminology so it would be handy is you could use this as it would make it easier to understand your problem.

It stays in whatever cog I put it on by hand. The derailler tries to shift but cant get the chain to change cog.
I can turn the bike upside down and get it shifting but when I turn it back around it doesnt work.

On the subject of derailers and how they act when the bike is upside down, I have found that they act differently when the bike is upside down on the ground and when the bike is in a repair stand. Don't know why. Small difference, but enough to mean the gears wouldn't engage properly when cycling.

Rule #49 // Keep the rubber side down.

It is completely unacceptable to intentionally turn one’s steed upside down for any reason under any circumstances. Besides the risk of scratching the saddle, levers and stem, it is unprofessional and a disgrace to your loyal steed. The risk of the bike falling over is increased, wheel removal/replacement is made more difficult and your bidons will leak. The only reason a bicycle should ever be in an upside down position is during mid-rotation while crashing. This Rule also applies to upside down saddle-mount roof bars.23
