Shifting into Smallest Cog some times struggles....

I know you are not meant to change gear when you are putting too much pressure on the drive train, IE going up hill very slow while standing... or am I wrong?
However, today while out for a ride the gradient changed a little, not a lot but enough to realise things were going to get harder in the next couple of pedal strokes, so I go to change to the smallest cog at the front, however all I get is that clicking sound you get when gears wont shift over, it wont shift and i end up coming to a standstill and push it up the hill. Once on flat ground it plops down nicely as it should.
When on the bike stand it changes gears fine, from smallest to largest with ease.
So how do I adjust for this? Or is there some thing wrong with my drivetrain?
Please help, its getting annoying stalling on the steep climbs!

Make sure you are in the one of the largest rear cogs when you change.
Also check the cables are not gunked up, and the derailer cage is at the right height, right angle and limit stops are correctly set.
Park Tools has a great guide.0 -
There's loads of stuff on YouTube showing how to adjust gears0

Under tension gears behave differently. Try adjusting the angle of the front mech. Rotating a degree or so will help.A Flock of Birds

Thanks mate, will give that a whirl... assume would need to move in, towards the frame?

The problem is when im on the bike though, I cant find any thing on Youtube about my particular problem, its not just gears not shifting correctly.

Yeah I was towards the large cog at the rear.0 -
Try Park Tools website, have a step by step guide.0

But look at what? My point is the gears shift fine when on the Bike stand or when im just riding along. Its as soon as there is a little bit more pressure (cos im going up hill a little bit) on the cranks that the problems arise.
What is it that I should be looking for on hte Park Tools website?0 -

Take the whole lot off, clean, lube and start from scratch.
It may be that a little flex in the cranks is causing this, but my guess is the adjustment is slightly out somewhere or the cables are periodically playing up. In the stand, and on the trail under pressure changes the conditions, though often the stand adjustment will suffice.
Or when you are riding, use the barrel adjuster to vary tension. If still not changing, then almost definitely the derailer is not spot on. Aso check the chainrings are not worn.0 -

Thank you mate, Hope to have a look at this later today.
Will let you know my findings!!0 -
You'll nail it! Can be finicky things, with tiny adjustment windows. But keep at it!0

Qwerty, what bike have you got?
I have the same trouble with my Carrera Fury disc. The problem is that the front cable comes out of the guide under the bottom bracket and needs to be moved back into it. It gets bloody annoying going uphill but I'm hoping it was a teething problem and it'll wear itself in.0 -
mine was the same, its sorted itself now and stays where it should be.random man wrote:Qwerty, what bike have you got?

Think I may have found the problem.
I was cleaning it today and while on yhe stand i moved to the largest cog front and back. Now when i got under the bike so my eye level was in line with the chain, i could see the cassete on the wheel apeared to be a little bit too far to the right, meaning the chain did not run in a straight line. It sounded like it was catching on the front deralier but there was a 1mm gap between the cage and chain so know that is ok, but due to the chain being at a slight angle, when the chain reached the front cog it caused a noise.
How do i solve that? i have not removed the spindle on the rear wheel before, but could taht be off center do you think?0 -
Should never be in big/big. Angle too severe, noise you heard is probably the chain catching on the teeth.I don't do smileys.
