Chain life on 27/30 speed bikes.
I have a 24 speed bike but may convert it to 27 or 30 gears, depending on
what parts I can get at the right price. Question is are the chains thinner for use with 9 or 10 gear cassettes? If so are they as robust? |

More expensive but not drastically less robust than 8s..MUCH more expensive tho, particularly 10s. I snapped the chain on my 10-speed bike last year. Replacement chain was close to $50. I have never snapped a chain on my 8- or 9- speed bikes. Even if I did, replacement chains are dirt cheap. YMMV. Honestly, I don't see a big motivation to switch to 10-speed...you generally save a few grams and get smoother shifting, but the costs (parts/maintenance) are significant. If you're *really* determined to have a 10-speed bike, I would suggest buying a new (stock) bike rather than upgrading an old one. To upgrade, you generally need to replace shifters, crankset, derailleur, and cassette. In replacing the cassette, you may require new hubs (and perhaps wheels). Your current frame may make upgrading a hassle (and chances are that you wouldn't realize it until *after* you've purchased parts). I'm sure I'm missing something here. Not only that, but I've seen 10-speed bikes going for just over $1k. $1500 gets you a pretty decent ride these days. |

All my MTBs are 3 front and 7 rear, giving me 21 speeds and I have never broken a chain. Also I have never felt like there was a gear missing between shifts. Your legs can go from 0 to 120 RPM, which is already a lot more range than a car engine has. They may make some sense for 'some' of the racer types, but I would hate to be standing on the pedals climbing (attacking?) a hill when the chain broke, possibly leading to a near neuter event.

If so are they as robust? Yes, they are thinner, or, to be precise, the side plates are thinner. Are they as robust? My experience (between 8 and 9-speed chains, no 10-speed for me yet) is that there is little difference between the durability of the two sizes. -- David L.

To be precise, 10-speed anything is way more expensive. 8-speed Campy parts are now more expensive than comparable 9-speed (cassettes are not only more expensive in 8-speed, but hard to find, and when you do you have essentially zero choice of gears). -- David L.

To upgrade, you generally need to replace shifters, crankset, derailleur, and cassette. My Aunt Harold's mustache. For shimano and Campagnolo all you need is the shifter, cogset and chain...NO need to change cranks, ders and such. In replacing the cassette, you may require new hubs (and perhaps wheels). Only if the bike is about 2 decades old is shimano or a decade old if Campagnolo. PLUS most hubs are convertible to 10s, freehub only.
