Previous threads and literature suggests that the closer the cogs in 10 & 11 speeds makes for better friction shifting. What has been your experience? Like others, I have had mixed experience. A few observations - 1. On a very springy frame, derailer cables get yanked when you push hard on the pedals. I have a Terraferma that's so flexible even I can make it swing. I currently have some Cyclone derailers and Silver 1 shifters on that bike, with a 9-speed cassette, and there's no way I could tighten the shifters enough to keep it from ghost shifting if I do an out-of-the-saddle stoplight sprint. Other than that, it's a nice, smooth-shifting experience. It can be a little tricky to quiet the rear derailer when a cog is between clicks of the shifter. Which leads to ... 2. The reduction in derailer actuation (the ratio of derailer movement to cable movement) has been driven by the desire to have more cable movement per cog, to improve index shifting. The same effect can be felt with friction shifting, especially with shifters that use a micro-ratchet mechanism (like Silver). If the derailer requires only a small amount of cable movement to shift one cog, I find that the shifter can be between clicks, requiring one extra click then a slight shove forward. This gets pretty fiddly and would certainly be annoying if you're riding with the carbon folks or are oxygen deprived at 13k feet. Which leads to ... 3. The Simplex retrofriction bar-end shifters are absolutely perfect for shifting SRAM "exact actuation" (1.30 derailer actuation) derailers over 10-11 speed cassettes. The 1.30 derailer actuation requires a fair amount of cable pull, and the Simplex bar-ends pull a lot of cable. Being retrofriction instead of ratchets, you never have the problem of being between clicks. Don't go putting Simplex retrofriction downtube levers on your bike and think you'll get the same experience, though. The downtube levers pull much less cable. Bottom line ... you have to match your friction levers to your derailer and cog count combo if you want a system that works without a lot of fiddling. Not that fiddling is bad, necessarily. But you also should feel free to decide that indexing is better for your style of riding.
