I Have 2300 componentry with a 12-26 cassette.. will an 11-28 work for me without changing derailleur?
859508
Check Shimano's documentation for maximum tooth difference for the 2300 RD. Chances are it'll work, or at worse, only support the 28t in the small chain ring. The cheapest option, of course, is to pedal harder.

Hello Mike here: I am not familiar with the 2300 so I don't know how many sprockets are on it but if the number of sprockets are the same I am pretty sure you will be able to use the same derailleur. I hope this helps.
859510
Yes it will work. If you change to a 9 or 10 speed you would need derailleur.
859511
I can't completely answer your question. I have a Tiagra derailleur and I must say it took some time to adjust so that the 28 didn't hit the derailleur. But after some adjusting, I'm very happy with the performance.

28 isn't much more than 26... it only needs 2 more links of chain. same derailleur should be fine in my opinion (used to work at a bike shop) but if you shift to the LARGE chain ring in front and the 28 cog in back (a gear you should NOT be using anyway due to extreme chain angle) then you may find your chain is too short and the deraileur arm on bottom will be pulled really far forward. When you change cogs, if your old chain is really worn (1000's of miles riding), it's a good idea to get a new chain too, and a new chain would be sufficiently long. you'll need a chain tool to cut it to length though (again make it just a little longer than your old chain).

I second the comment that cassettes for 7, 8, and 9 are compatible usually on the same hub. Your derailleur and shifters will determine how many of the gears in the cassette will be used.

You have to change the hub out to accept a cassette. Freewheels only thread on up to 7 speed. I'm pretty sure about that but your local bike shop will know for sure

I think it depends on your cassette. It's meant for 9-speed cassettes. On Shimano's website, it's listed under the mountain bike parts. The Shimano road bike derailleurs are the Dura-Ace, Ultegra, 105, Tiagra, Sora, 2300 and 2200 series.

Changing from a 5 speed freewheel to a 6 speed freewheel will work if your rear derailleur is designed to work with a 28 tooth gear. The web site www.disraelligears.co.uk may give you this info.

Not sure about the cassette. Your best bet is to talk to your local bike shop. Make sure your front derailer is compatible with your new crank though.

I have a Jamis with an 11-32 cassette and this chain was original equipment. I am now using it as a replacement chain. SRAM derailleur and cassette, but I don't think that matters.

I would think the CS-6700 cassette would work for you but it may not cure your skipping issue if that is from a misaligned derailleur or a derailuer cable problem. If your old cassette is more than a couple of years old and the teeth are worn down a new cassette should help otherwise you'll be disappointed to have the skipping issue after changing the cassette.

First, I don't know. I have found calling Shimano Customer Service line to be very helpful when I had the same question. But in my experience as long as the number of speeds is the same, and the largest/smallest sprocket size is the same, you should be OK. Again, you should call Shimano to confirm. It is based on the derailleur, and in my case, I discovered from Shimano customer service that I was able to keep my same derailleur when I made my switch.

You can use a Dura Ace chain without issue. A KMC X10Sl chain is another less expensive option / upgrade. It just needs to be a 10 speed chain. You don't need to buy another 12-30 cassette if you want to get something else. For example, an 11-25 would work just fine but you may need to shorten the chain. Park has a chain length calculator here http://www.parktool.com/blog/repair-help/chain-length-sizing that works really well and takes the guess work out of the determination. As far as adjusting the derailleur is concerned, most likely nothing more than a slight barrel adjustment is all that will be needed. Have fun.

As important as verifying that it has square bottom-bracket fitting, which it likely has, is making SURE the gear-teeth/ratios numbers match..whatever your old one is, it will create problems and more work if you try to fit one smaller or larger number of teeth, the front derailleur will not be in the right position and adjustment for a start...if your largest cog is 42T, you will be easier off with another with 42T, best to get the middle gear the same such as 34T or 32T, as well.

I believe the photo is errant. What I received was a 7 speed. You definitely don't want to substitute an 8 speed on a 7 speed application. You'd have too much slack in the shifter cable (in position 8 on shifter) even if you adjusted the deraileur stops to avoid the chain falling off, and an annoying dead spot gathering up that slack when shifting back into the lower gears.

first, if your bike has road bike style crankset, then there are no 22t sprockets for it. though a mtb crank will fill a 22t. second a 32t cassette will get you up any hill with a 30t crank sprocket. also the 11-32 has a smoother gear ratio between sprocket then 12-34. If you decided to swap cassette, make sure that your chain is long enough as well as your derailleur cage.

I put that crankset on my hybrid which was set up for a 48. Using a 48 on your bike will require moving your front derailler up some and it is possible that your rear derailler won't have the capacity ( length of the derailler arm) for the larger gear. However it possible to change the ring gears on most crank sets and you could use your old 42 gear. I'm not sure about this but 8 speed set ups might not have compatible gear teeth with 9 speed crank sets.

Okay, so it's not the model of the bicycle, it is the compatibility of the components that work together. So yes, if you have 3 chain rings in the front and 7 cassette or freewheel cogs in the rear, most likely it will work. However, there are other factors: derailleur (the mechanism that reacts to the pull or push of the shift pod to change "gears") ratio (Shimano is about 2:1 units in the shift mechanism, so you need a derailleur that has the same 2:1 pin/rivet/bolt unit ratio), or something in need of replacement or readjustment.

I've not attempted to add and 11 speed cassette to this wheelset, so I'm not fully sure if it'd fit. However, all you have to do if measure the dimensions of the cassette against a shimano 8 speed cassette. If it's the same, it should fit. If it's smaller, you may need a spacer.

If you're derailleur is a shimano tourney this should work fine without a longer chain. The freewheel tool for the removal of the old freewheel is the only tool you'll need.
