ive been thinking about how cool a 13-23 cassette would be lately, and decided to do some research.

shimano 9 speed cassettes are built in chunks, where the last few gears are connected.

my question is why? if they make gear combos of [16-17], [17-19] and [19-21-23], why cant they stick an 18 in there?

cutting off the 12T and making the [17-19] into a [17-18] and leaving the 16T as a loose sprocket seems like a good thing to me. (im sure this makes no sense, so you have to click the link)

so I guess my real question is, is it really impossible to get a 13-23?

I have the same problem.Dutchy

I also wanted to sacrifice my 12 for an 18 but so far have had no luck. I even had the LBS
contact the Shimano Distributor, for a custom one and they said "no". The only way to do it is to
get rid of the Shimano and buy Campy. I got tired of trying to figure this one out, so I have given up and
will keep my 12-25 until I can afford a new bike with the 10spd campy gears.

i think shimano actually has a 13-23dupe

I was hoping someone would mention the Mavic cass.litespeedcat

This is the way to go. follow the link in the reply above and buy the most versitile cass. on the market. The Mavic is of the highest quality and you can pick exactly which gear combos you want. This is the best available.
Are they Campy Rec or Shimano DA Quality or what??? nmjagiger

I used to cobble together my own cassettes. If you're not too heavy, you can leave the cogs loose (I used to take out the bolts so I could pitch the biggest cog and put in another in the middle range), but you have to make sure you REALLY tighten the cassette onto the freehub body. Part of the reason the larger cogs are bolted together is to give the higher torque gears a larger contact area with the freehub body, lessening the chance that the splines will either strip out or cause indentations on the freehub.
