I've disassembled my acera rear derailleur and have forgotten which cog/sprocket goes where. One of them has an offset. What are the symptoms if I have them interchanged? TThanks Allan L

Generally there is no much difference, but as I remember in acera they have different sizes: the bigger one goes to the bottom (down), smaller one goes up.
As for offset you'll just have to readjust your rear derailleur. (If you disassembled it you'll have to readjust it anyway so no big deal)

I have an electric RMartin R10H, and replaced the 9c motor hub. But, the derailed is no longer aligned. Cog needs to be moved outward by 3/8 inch or so. Is such an extender available?


Are adjustment screws all the way out? If so, frame won't accommodate this cog. ITs too wide. Sometimes a frame spreader will correct. This repair is difficult to do, contact local bike shop for assistance

What are derailleurs?


The derailleur is responsible for changing the gears by moving the chain from one sprocket to another. Bicycles usually have 2 derailleurs: Front and rear. When bikes are faster (on the higher ratio) the chain is located in the biggest sprocket in the front and the smallest in the back. When the bike goes slow it means that the chain is located on the smallest sprocket in front and on the biggest in the back.

The chain is broken off the bike We bought a new one but need a diagram of how to weave the chain through Thanks


The chain goes from the top of the front sprocket to the top of the rear sprockets, between the rear sprocket and the top derailleur wheel and then between the upper and lower derailleur wheels. It then goes forward toward the front sprocket. The text sketch below shows the rear sprocket, chain and derailleur.I hope this helps.

I'm new to multi gear bikes..whats the reason for the 6 gear positions on the right and 3 gear positions on the left hand side


Bicycles have two sets of gears (front and back). The 6 position control slides the chain between the 6 sprockets (cogs) on the back. The 3 gears are for the front set of cogs. Between the two sets of sprockets, you get 18 (theoretical) different rates of chain movement per turn of the pedals. In fact some of the settings overlap. (However some of these should not be used. Do not use the settings that pull the chain to the furthest inside of one derailleur and the furthest outside of the other. This diagonal between the biggest and biggest sprockets (or smallest to smallest) puts extra strain on the chain.) The back derailleur is in the lowest gear when on the biggest sprocker. The front low gear is on the smallest cog. The highest gear possible is on the smallest rear cog and the largest front cog.

By planning the shifts in gears, you can maintain the same speed and cadence (rate of pedalling) on different terrains. (For going up a hill, use a lower gear than on flat terrain. However don't go to low or the bike may not balance well.) To shift through a large range of gears, you must be pedalling and then move the rear derailleur control followed by the front derailleur then the back again. (For faster shifts to a low speed, you can shift the front derailleur first but that can stress the system.)

For a guide to using the gears: http://www.southcoastbikes.co.uk/articles.asp?article=Gears .

I hope this helps.

I have a TREK mountain bike with a Shimano combination brake and shifter with an Altus derailleur. It shifts all gears fine but when coasting with my feet on the pedals, the chain goes slack and sags...


Only YOU can evaluate any error you may have made. LOOK at why the chain is slack. Does the rear derailleur pull back to take up the slack? Are you using some ridiculous small chainring, small rear cog combination that allows too much chain to go slack?

Perhaps the freewheel isn't freewheeling and is instead feeding chain forward when you stop pedaling. Walk the bike forward and see if the rear cogs just coast. If not, lube time (internal). take it to a Bike Shop or buy all the special tools and DIY.

Colnago C50 with 11 speed choras group set. When changing up to the big chain ring ready to decend whilst still in one of the largest 2 or 3 rear sprockets the chain...


Is the chain falling off to the outside? if it is you can adjust the "High " limit screw on front derailleur. There are two screws on top of derailleur usaully marked with a L or a H.Shift rear to small cog and front on large ring. Slowly turn screw marked H till you see front derailleur move in. When it starts to rub on chain back off 1/8 of a turn. Run the rear up and down a cuople of gears making sure nothing rubs and adjust accordingly . Same with the front. That should do it! Also when changing to the big ring up front you should try to be on a middle to small cog on the rear so you don't get into a "cross chain" situation. When running on the small ring you should be on large to middle on the back. Hope that helps you out.

Trek 6500 Shimano deraileur adjustment issues


Derailleur adjustment takes time to master. Try this out:
First, wash your drive train out really thoroughly and use a degreaser (Simple Green works really well) and a chain brush on the derailleur and chain. Rinse it off and let it dry, then relubricate the chain (and ONLY the chain - never lubricate your derailleur). Now flip your bike onto the bars and saddle so you can crank while you shift manually. Use the middle chainring up front to adjust the rear gears. Okay, shift into your highest gear in the back and then release the derailleur cable. Use this opportunity to make certain your "H" setting is good; the derailleur's jockey wheel should be perfectly aligned over the small cog. Now manually push the derailleur to the lowest gear (while pedaling) and set the "L" so the jockey wheel is immediately outside the last cog. crank back to the high gear. Turn the barrel adjuster for the cable tension to its half-way point (figured by unscrewing it all the way and then counting revolutions as you screw it back in). Pull the cable taut and reattach it. Shift into your middle gear (or if it is an even number of gears, pick one of the two middle gears). Use the barrel adjuster to get the jockey wheel exactly over the correct cog. Pedal and shift through the gears. In each gear, back-pedal to make sure the chain is not skipping. You should be able to free-wheel without problem in every gear on a properly adjusted drive train. If the gears are requiring much adjustment on the barrel adjuster, then you may have a bent derailleur hanger. This can be straightened manually without tools if you have a good eye and patience. If it goe that far, come back and repost "bent derailleur hanger".

i hope this helps

I do not know how to correctly adjust the shifter cable-I have a 7 speed mountain bike-what are the procedures to make sure the tension is correct and properly shift to all gears. It is a trigger shifter....


Assuming that the limit screws are set correctly on the rear derailleur, which they probably are if you haven't fooled with it, and your cables are okay, here is what you do. If you don't have a bike workstand, then get someone to hold the bike up or hang it off the ground with a rope. Turn the cranks and shift to the highest gear (the smallest and outer rear cog). If the chain does not go out to it, then screw the barrel adjustment in the rear derailleur (where the cable goes into it) in until it goes to the outside cog. Beginning with the chain on the outside cog shift to the next lowest gear (keep turning the crank at all times) If the chain does not go to the next smallest cog, then turn the barrel adjustment out until it does. Now try shifting it through all the gears to the inside cog and tweak the adjustment with the barrel adjustment. Also, you might have to take out slack in the inner wire if it has "stretched" out, by loosening the cable bolt on the rear derailleur, pulling the cable tight, then retightening before any of this will work.

Adjust Shimano Acera back derailleur


There is a limit screw on the body of the derailleur that you have to back out slightly. You can tell which one of the two it is by watching carefully as you adjust it. It takes a phillips screwdriver.
