Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

As long as you're running it in friction it's be OK. However the cage is a bit narrower so you might (might possibly, not necessarily will) have some chain rub where the lower loop first enters the RD when coming from an angle, ie. outer ring inner half of the cassette.

Also with derailleurs with a floating upper pulley, then chain might (again- might) touch the cage when the pulley moves to one side.

Question --- 11s derailleurs tend to be much pricier than their 9s and 10s counterparts, why do you want to pay more than you need to?

I'm sticking to Shimano for the time being. To shift up to a 32 tooth large cog in the back with a double in the front I'm looking into either 105 GS or Ultegra 6800 GS. You make a point, upgrading to Ultegra may prove financially unnecessary for this application. It'd be nice for the build to feature Ultegra throughout, but I'm learning that with time I'll have to become increasingly more comfortable with mixing and matching to achieve exactly what I'm envisioning. I'm confident an 8s chain and cassette would work fine with 10s derailleurs.

Does it need to be brand-new? There's plenty of Shimano stuff from yesteryear that will do the job perfectly.

'speeds' is just shorthand for (now) packing 11 cogs in the space of 8.. a Stack,

more pancakes but thinner. RD will move responding to the cable pulling it

sideways , via the parallelogram part of the RD. till it hits a travel limit setscrew..

cyclists got along without their derailleurs going click between shifts for a long time, decades,


if the gaps between the cogs is wider, friction shifting gets less fussy .

I prefer older tooth patterns on the rear cog , as I grew up learning
the traditional overshift an pull back on the lever,
And find I liked that it stayed on that cog until pushed off ..

the recent hyper-glide can pick up the chain and ghost shift when you want it - not.

yea no need for 11 speed RD.. pay more attention to the biggest cog clearance and wrap-up

[difference between maximum tooth-count, total and the minimum tooth total numbers (f+r)..]

If that's the case I'd grab some BB pulleys; they come with a variety of collars to fit various drivetrains, and BB>bushing.

Don't get ally ones though, they're noisy. I can't find them with a quick google, but at work we get these ones for less than $10 a pair that fit the description. The upper pulley doesn't have float; it's just thinner instead. Works fine, but I guess it'll wear quicker.
