Re: [RBW] Turkey Vulture Gearing 101

After working plenty with 10-speed systems, I've been moving more toward friction shifting and 9- or 8-speed systems. Having said that, I set up a flawless 11-speed transmission with the following: - Shimano 11-speed 105 brifters - White Industries 46-30 VBC road crank (also have 42-26 rings,

Re: [RBW] Turkey Vulture Gearing 101

Resurrecting an old thread, but I made a chance discovery that may be of interest to the group. One limitation of friction-shifted 10 and 11 speed bikes has been the throw length of bar-end shifters. Some people have gotten around this problem with judicious filing of the bar-end pods, like

Shortly after this thread paused I broke my duraace dt 10 speed shifter. I ended up replacing it with that diacompe 10 speed / 11 speed dt friction shifter Justin mentioned two post prior. Just rode a century with it on Sunday. Worked amazingly well combined with a short cage shimano zee

Re: Friction shifting 10 speeds with Silver shifters (Was: Re: [RBW] Turkey Vulture Gearing 101)

Keep in mind Shimano 10 speed road and mountain have different amount of pull. 10 speed road has the same total pull as 9 speed, so the pull for each shift is less. 10 speed mountain (Dynasis) has significantly more total pull, and the pull for each shift is greater. When Shimano dynasis

Re: Friction shifting 10 speeds with Silver shifters (Was: Re: [RBW] Turkey Vulture Gearing 101)

Interesting indeed! Might be time to revisit. Another interesting thing is that on Paul thumbing mounts Shimano 8 speed barend shifters pull enough cable to sweep the whole cassette 8, 9, or 10 speed with a Dynasys rear derailed. But, when mounted on the bar end pods they come up short on the

I use a 9sp MTB triple with a small 22 front and 36 rear on my general riding and touring bike (Specialized AWOL), and I have found times I would have been glad to have a 40 or 42 in back on loose steep and/or very long loaded climbs. So sorry I schlepp too much gear to suit you. I find it

Re: Friction shifting 10 speeds with Silver shifters (Was: Re: [RBW] Turkey Vulture Gearing 101)

And yes, I am glad to confirm that the Silver shifters pull plenty of cable for 10 speed on a standard pull derailleur. Don't know about a Dynasys one. I'd been planning to try it, but I think I'm gonna abandon that project now that I have the Velo Routier. I'll go so far as to say that 10 speed

Re: Friction shifting 10 speeds with Silver shifters (Was: Re: [RBW] Turkey Vulture Gearing 101)

Good call Daniel! I bet that's why. It had never occurred to me that a narrower chain and cassette might be beneficial, but here we are. Neat! I'm happy to leave my other bikes on 8 and 9 speed, though. Reed On Friday, September 16, 2016, Daniel Jackson wrote:

I don't know if the road Microshift rd I used was a Centos; I expect not, because it was several years old and had no big Centos on it. But whatever it was, it was the very best shifting rd I've ever used, and shifted 9 mismatched with Silver BESs better than the current 8 speed Dura Ace does.

My main reason for asking Clayton the question in the other thread was just to be sure that the Silvers can actually pull enough cable to work with 10 speed. I imagine there is no problem as overall cassette width between 10 and 9 speed is negligible. -- You received this message because you

Re: Friction shifting 10 speeds with Silver shifters (Was: Re: [RBW] Turkey Vulture Gearing 101)

This is fascinating - I have heard both that friction shifting 10 sp is easier and that its harder than 9 sp. The main reason I've heard for the former is that there is less space between gears so you're never "out" of gear as you might be on a 9 speed. On Friday, September 16, 2016 at

I'm really close to where you are at, Philip. On my touring bike, I'm currently running 44/28 with a 12-30, but I'm converting to a mountain rear der so I can swap back and forth between an 11-32 and an 11-36. I'll move the 12-30 and the road derailer over to a roadier bike. 44x11 will be

10 speed works fine for me. running 40/26, 11-34 right now, its pretty sufficient. once things wear out, gonna go 44/26 and 11-40 for extended climbing with load, while getting more on the top end. i like the power ratchet shifting on the silver shifters, but the plastic washer broke on me

2x10 friction here with SLX RD. I use Microshift shifters in friction mode, I've used 8,9, and 10 speed friction. After a few shifts I get used to the cable pull and never think about it again. On Friday, September 16, 2016 at 2:08:41 PM UTC-4, Reed Kennedy wrote: > > On Fri, Sep 16, 2016 at

I don't use friction with 10 speed. Too fiddly especially when tired. That is not a function of the type of friction shifter though. For friction I use 8 speed drivetrains and for that the silvers are great. They don't slip if treated right. I am still amazed a bike shop can't make them

Just a guess on my part, but with the capability of modern materials and manufacturing techniques chains could be made to last much longer, but it would cost a whole lot more and there just isn't enough of a market for that to make it worthwhile. If I were going through 20-30 chains a year, it

I have put 10s of thousands of miles on 10 speed chains and have had no issues. I generally replace chains every 2500 miles no matter what. Saves the drive train in the long run and chains are cheap. 10x are a female dog to friction shift, but my indexed setup stays good for thousands of miles
