It's a geek disc (kidding). If you lost it, leave it. It's just there for those who have maladjusted rear derailleur Low Limit adjustments, which limit the distance the derailleur can approach the spokes on the lowest gear.

The problem lies in cable. Check out what make of front derailleur (cog shifter) you have (Shimano, SRAM, e.t.c.). Then visit the manufacturers website and check out for technical info and settings.

How do I remove the gear cog from the rear wheel of a mountain bike? I have tried with a freewheel tool, but it wont budge.


Take it to a shop and let them do it, you probably will only pay a minimum charge. We use a bench vise to hold the tool and then put the wheel with the cog on it, then turn the wheel.

How do i remove the rear gear cogs from the wheel of a mountain bike?


You must have a special tool called a cog removal tool, you can buy one from your local bike shop. Or, better still, it is cheaper to have them remove it for you because this is a tool that you will onlyl use probably once and your bike shop will usually only charge their mininum rate. Good luck

I'm a 60 year old female. Only just learning to ride a bike. Husband been riding for 60 years and doesn't seem to understand my problem! I have a bike with SI-6KT0B gears. I understand the principles of...


Congratulations on learning to ride the bike. I use the rear gears mainly i.e. the gears on the right hand side. Each rear gear makes a little difference so it makes it a little easier to go uphill. (When the chain is on the back smallest cog wheel it's hardest to pedal and easiest on the largest. The reverse is true of the front cog wheels) If you come to a very steep hill you should use the front gears i.e. the lever on the left hand side. This makes a bigger difference to the effort needed to climb a hill. When you have put the front gear into the easiest position, (on the smallest cog wheel) you can still use your rear gears to make it easier still. For going on flat ground or downhill most people keep both sets of gears on the hardest gear. (The front gears on the largest cog wheel and the rear one on the smallest) However there's no rule that says you have to. Use the one that feels you're using just enough energy to turn the pedals and in time you won't have to even think about the gears. I hope this helps.

Problem with chain and gears


Wash, degrease and scrub the chain and derailleurs with a good degreaser (like Simple Green). Dry the chain and relubricate it with an appropriate bike chain lubricant (not oil or WD-40). Shift the derailleurs to the smallest chain ring and cog on the cassette (low front gear, high rear gear) and then loosen the cable at the derailleurs, pull the cables taut and reattach them. If the derailleurs still need adjustment, here is a procedure for it:
Flip the bike over (so you can pedal the bike manually while you shift) and shift the front to the middle chain ring. Shift the rear to the highest gear (small cog). Release the cable from the pinch bolt on the derailleur. Adjust the screw marked "H" on the derailleur until the jockey wheel on the derailleur is aligned perfectly over the small cassette cog. Set the cable adjuster on the derailleur to the middle of its range (find this by screwing it all the way in and then count how many revolutions it makes until it screws out completely. Screw it back in one half of the total revolutions). Reattach the cable and shift to the lowest gear (the biggest cog). Over-shift and hold on the shifter, then adjust the "L" screw on the derailleur until the jockey wheel sits just past the last cog. You have to hold the shifter to do this. Now shift into the middle gear (or one of the two middle gears if the bike has an even number of gears) and adjust the derailleur using the barrel adjuster you previously set to the middle of its range. Adjust it so that the derailleur is sitting perfectly over the appropriate gear. Shift up and down the cassette while pedaling and in every gear, reverse pedal (freewheel) to make sure the chain does not hop. Adjust as necessary until all gears are smooth.
Now the front:
Set the rear derailleur to the lowest gear (big cog) and the front to the lowest gear (small chain ring). Disconnect the derailleur cable. Screw in the adjuster for the cable tension all the way (this adjuster is on the shifter of a mountain bike or the down tube of a road bike). Pedal to make sure the chain is not rubbing on the derailleur cage. If it is, adjust the "L" setting on the derailleur until the chain moves by without touching the cage. Now pull taut and reattch the cable and shift the front to the big ring while pedaling. If it does not shift up well or completely, hold the shifter past its normal shift and adjust the "H" screw so that the derailleur allows the shift. Shift into the highest cassette gear and keep pedaling. The chain should not be touching the front derailleur's cage when you pedal. Adjust with the barrel adjuster until the chain moves freely without touching the derailleur cage.
That should be it, unless there is another mechanical problem causing the missed shifts, like a bent derailleur hanger or damaged teeth on the cassette cogs or a bad derailleur. If it is still problematic, come back for further information.

i hope this helps

What the best way to take the back wheel of my mountain bike


Shift to your top gear before removing the wheel and as you take the wheel out, pull back your derailleur to make it clear the cassette more easily.

How to remove the cog on back the wheel of my mongoose bike


You'll need some tools:http://www.parktool.com/repair/readhowto.asp?id=48 There are various tools for various freewheels. ACS is different from Shimano for instance. The procedure is pretty much the same for all of them:http://en.allexperts.com/q/Bicycle-Repair-1824/cog.htm
