Need better gearing for hills, any suggestions?(7 posts)

|I current have a campy chorus 12-25 cassette with a double in front. I would like to get gearing that's more fitting for all of the hills I do. I'm trying to avoid having to get a triple. Should I just swap for a 13-26 cassette or should I just swap a couple of the sprockets? My bike is fully Chorus except I've got record crankarms.
Thanks in advance.

|There's hardly enough difference between a 25 and 26 to be worth buying a new cassette. You can't just swap a couple of cogs becaused they are pinned together and only shift properly in the succession provided by the stock cassettes.
The full listing of cogs and cassettes is available at campagnolo.com or branfordbike.com.
If you want a significantly lower gear, you'll have to use a 13-29 cassette with the double. Some folks have been able to use this cassette with the short cage derailleur, but there is no guarantee that it will work. Campy insists that the medium cage derailleur be used.

|assuming yours is 10sp, it would also be possible to leave out the 16t (I know...many would not be happy w/o it) and combine parts of a 12-25 and 13-29 cassette to make a 12-29. Also, I'd reccomend getting a Centaur cassette rather than Chorus...have have problems w/ creaky riveted cogs w/ my Chorus cassette....only 2 cogs are riveted on Centaur vs. 6 on a Chorus 13-29. Seperate cogs are expensive, especially the bigger ones, so it is cheaper to buy a complete cassette if you need several.|

|he already has a 12-25...if you started from scratch w/ a 13-29 you would need to buy a 12 and a 13...the 13 that comes w/ the cassette won't work as an intermediate cog, is made to work w/ the lockring.|

|The Campy 13-29 has all the gears in your 12-25 except no 12, a 26 instead of 25, and the 29. You won't notice much difference between the 25 and 26 gears, but the 29 will give you a lot more climbing power. I don't need the 29 very often but it very nice to have when I need it. The only downside with the 13-29 cassette is the lack of a 12 gear for long downhills, but you can't have everything. As others mentioned, you also will need the medium cage rear derailleur with the 13-29 cassette.|

|I also had a 12-25 and wanted a little extra I bought a 23/26 chorus cog( sold in groups) and replaced my 23/25. It's works and shifthes great.|| |
