Bar End *friction* shifters and Shadow plus
I have a drop bar mountain bike conversion that I've been riding more aggressively lately, and the Altus rd (which I put on as a $12 solution when I didn't know how much I'd like this build) is no longer up to the task. I think I want to switch to a clutch rd like one of the shadow plus deores or thereabouts. I currently run 7 speeds in the back, but want the flexibility to run 10 speeds / 11-36t (would be achieved by cold-setting the dropouts out an extra 5mm at some point in the future when I've cooked the rear wheel). Using a 9sp chain. I suppose a right hand rear brifter wouldn't be such a huge deal if I have to do so, but I like the simplicity of the current friction setup. Could see it going to 1x w narrow wide chainring in the future as well. Any recs for achieving that versatility w clutch derailleur would be welcome.

I asked a similar question not long ago.
The cheapest answer I got was "probably". The best answer I got was that microshift makes a 10 speed bar end shifter for mountain bike derailleurs. I got both these answers from the same guy. I still haven't decided which way to go myself. $30 and ghetto vs $90 and right. I'm leaning towards microshift. BTW, I'll be starting my build with an 11-42 cassette and a 38 tooth narrow wide ring. This will be on an old Voodoo steel CX bike. I'll run 38mm tubeless. Basically a severe gravel, bikepacking, maybe touring, definitely commuter, and hauler of baby trailer. Depending on how it rides, I may switch to a 42 front ring. |
I have the Microshift 10sp index barcons on a different bike, and they're great - they work perfectly every time. The bike in question has friction-only Suntour barcons, but it has an Altus rd. I'm looking more for a rd clutch derailleur recommendation that'll work with the current 28/38/48 triple I have up front and the 11-36 future cogset in the back. And have the ability to switch to 1x (probably 40t) eventually on this particular bike. Is there a particular model of Shimano shadow plus I should be looking at for this upgrade to the build?

Here's an article on how to trick Dynasis derailleurs into a shorter pull ratio: https://www.pinkbike.com/u/SupraShin...o-9-speed.html I've never screwed around with this stuff, but I'm assuming that the pull ratio takes so much cable that a regular bar end shifter isn't going to be able to go the full range. There are friction shifters designed for more cable pull, but I don't think anyone has combined them with a bar end pod. So changing the pull ratio of the derailleur is another way to go. Of course, you could also just buy a set of Ene 11 retrofriction downtube shifters and modify the bar end pods to fit them. You're just creating more drum clearance. |
both levers friction? main issue will be upping your hand skills to hit a narrower target ,
because of the tighter spacing .. you may want to consider N+1.. buy a new bike with all the new stuff on it, rather than pour a lot of money into what you have.. relegate your current bike to winter commuting or something.. ... |
Both sides are friction. No issues controlling 7 speed shifts right now. The Altus just has a weak spring and bounces around too much on bumpy terrain aka too much ghost shifting. Re N+1, I have enough bikes, this one just needs a different rd (also, $60 or so versus $1500), and I'd like to have one that won't introduce compatibility issues in the future should I switch out other aspects of the drivetrain. So the question is, with friction barcons, will I have any compatibility with shadow plus, and which shadow plus derailleurs fit the bill if I want to have the flexibility to use it with a current total range of 40t, and potentially a future range of 25t on a 1x?

I never said what I use. I've got a 10speed SLX derailleur. I used it last fall on a 1x mountain bike that I'd converted from single speed. It worked great up to 36 right out of the box.
I messed with the b screw and added some chain and it was fine up to 42. The derailleur hanger that I added to the horizontal dropouts was significantly shorter than a typical one, so on any other bike, that SLX probably could shift up to 42 without much adjusting. I'm moving the components over to my gravel build since I never ride a mountain bike anyway and if I do, it's on stuff the CX bike can do anyway. |
Shimano 10 speed MTB RDs move less per 1 mm of cable travel, than lower speed count RDs (and most road RDs). Shimano 11 speed MTB RDs move even less. So using such a shifter, it might not be as hard to "hit" the correct gear using manual shifting.
For "standard" Shimano RDs, that move more, up to 8 speeds is manageable with friction shifters, while going over that requires very precise hand movement. * Haven't tried to compare how it feels, but you'll definitely get more lever movement per gear change, so more room for error. |

I had been contemplating a similar build myself and again, based on the research, most people find going above 8 to be too finicky for friction. Sure, there were those that didn't mind it with a 10cog but most moved back down to 8. I've decided to just stick with the 7cog; really what does one more cog do? YMMV. |

YMMV. One more cog casette costs some 20% more and usually gives one higher gear ratio - not worth it for me. Just sad there aren't Shimano 7 speed rear freehubs easily available new. So I use spacers to fit a 7 speed cassette. |
