I ordered 9 speed cassette 12-36 and I'm just going to start with that. My current chain is pretty new, so I'm going to buy 1 piece at a time and see how it fits together. I'm going to do a little tour on it and see how everything feels. If I need to replace a lot of things, I should consider a new bike, but I love my bike and I'm definitely on a budget. ...

So you currently have 9sp, and you want to go to 6800, which is 11sp? Most likely Shimano would advise you that what you need to do is to buy the entire groupset. In reality, you could probably get away without replacing brakes and bottom bracket, although you'd probably find it cheaper to buy the set, rather than to buy the individual bits and bobs. As ...

Shimano 11 speed road cassettes are wider than previous models, so you most likely will need a wider freehub body. In some cases it can be bought separately, but given that you have 9 speed at the moment, I find it unlikely, so add an 11 speed Shimano road rear compatible hub to the purchase list.

See Klaster_1's comment. You could save a lot of cash by going for a 9 speed cassette with a larger large. Something like a 32 or 34 tooth will be available standard. Your rear deraileruer might be okay, and a new chain might be a good idea if the current one is worn. However you could get away with just the cassette. The other option is to put a triple ...

There are fixed gear bicycles don't freewheel. Presumably you have multiple gears, so its not fixed gear bicycle (or you know it used to freewheel). That being said, if it is really a French Motobecane (the Motobecane brand is now used for bikes sold directly from some Chinese factory), it probably predates the common use of a freehub and almost surely ...

You could do this for the front with a Mountain Tamer Quad (which is an adapter which turns a triple into a quad) and an appropriately chosen front derailleur. The chainline issues become more severe than they do with a triple. For the rear, you could use a 12 speed internal gear hub (Sachs Elan) or go up to 14 with a Rohloff Speedhub with a chain ...

Here is what I have for a progressive 3x9 setup using all 3 chainrings and all 9 cogs but using only 3 cogs per chainring. chainrings (20,30,40) cogs : (36,28,22,25,20,16,18,15,12) Ratios would then be: 20/36 = 0.56 20/28 = 0.71 20/22 = 0.91 30/25 = 1.20 30/20 = 1.50 30/16 = 1.88 40/18 = 2.22 40/15 = 2.67 40/12 = 3.33 Overall spread is 6:1 between ...

Yes, you could do this and done as you describe I think you'd end up with as many ratios as rear cogs. Someone once made a single-shifter derailleur system that moved both derailleurs from one shifter (using two cables) and "IXOV" has apparently started doing that again with the "Synchrobox" but all I can find are press releases, not even a company ...

It would most likely not work without a bunch of expensive finagling. Most inexpensive cassettes come on carriers, meaning removing individual gears is not really that possible. You can still buy individual gears, but they are a more specialty item and very expensive. After you messed with all that, you would likely find that the lower gears tore through ...

Seems like a lot of work for little gain. You'd be able to lighten by the weight of 7 cogs, but the shifting action will suffer. My early megarange was quite bad at the last change, which was 26 or 27 up to 34 You'll also need to install 7 cogs worth of spacers to hold the remaining three in a fixed place on the freehub. And I politely challenge the "I ...

The recommendation of Calvin Jones of Park Tool for a trail/road-side conversion to a single speed is: If you have multiple chain rings, put the chain on the 2nd-to-largest chain ring. I.e. if you have two chain rings, this will be your smallest. For the cassette, put the chain in a straight line back from the chosen chain ring. If in doubt, use the ...

Addressing only the technical compatibility, if you currently have a Shimano 8x3 setup, and you wish to upgrade to another Shimano 8x3 setup, then any Shimano 8-speed road parts should be fine. So that includes Claris, Sora, Tiagra etc. as long as it's 8-speed kit. Same goes for the chain. I mention Sora and Tiagra just in case you're able to source these ...
