[Yeah, I know...Surly and Riv....but they don't interest me]. I'd just like to see some high-quality, light frames with DT bosses, from the major manufacturers (as opposed to over-priced specialty boutique manufacturers).
Hmmmm...just got an idea: One'a these days, I'm gonna get me a Dengfu FM098 frame and try out an idea I have for adding DT bosses to a CF frame. |

No we're not. We're talking about the bikes manufactures offer to regular, everyday recreational riders in every bike shop. What realistic benefit is 11 (and soon 12) speeds to them?

The 12 speed cassettes aren't designed for use with triples, but rather doubles.
And it isn't a question of how many speeds, it's a question of total gear range and how close are they spaced. So, no, it's not overkill. |
without reading 103 replies I think I will just say what I have experienced recently. My new bike has 9 speed in the rear. 11/28. Previously I had 7 speed on my vintage. On the 9 speed the ratios are nice and close for the highest 4 or 5 ratios but somewhat big jumps on the low ratios. I would love to have that full range from 11 to 28 but would like closer ratios at the low gear end and still have the close ratios on the high end. This makes a case for more gears. I could use 11 cogs on the rear. Maybe even 12. I would have to change the rear derailleur and probably the hub but it would be nice. Overkill? Not for me. My power band is pretty narrow at age 70.

The least amount of difference you can have with a derailleur gearing system is one cog tooth. With bigger cogs, the percentage difference produced by a 1 tooth difference can be quite close. With smaller cogs, 11, 12 and such, the percentage difference generated is relatively wide. If I could add a 11 1/2 tooth cog between the 11 and the 12, that would produce a closer ratio. |

I don't understand what you are saying.

To get close ratios at the high end cassette cogs have to increase in 1 tooth increments because that's the closest adjustment you can make. To keep the ratios relatively evenly spaced at the low end, the increments need to increase by 2 or even 3 teeth.
