Our Shifters go to 11 and Other Minor Updates

by Clint

Dia-Compe 11-speed downtube shifters have landed. Retail is $85. Here they are on the site.

These are so much more than 11-speed downtube shifters. With over 50mm of total cable pull, these shifters will work with just about any derailleur. We've tested them on Shimano 11-speed road and Shimano 10-speed mountain.  Here's what you need to know:
  • Designed for 11-speed, but will work with fewer speeds;
  • Better option for 10-speed drivetrains than our other Dia-compe levers;
  • Non-indexed, micro ratchet design;
  • Right barrel is larger than the left for more cable pull;
  • Not compatible with bar end or "thumbie" mounts because of the oversized barrel.
For nerdy eyes only:
To calculate the amount of total cable pull your drivetrain requires use the following formula
total cable pull = cable pull of intended shifter * (s - 1) 
Where s is the number of speeds of your cassette. If the total is less than 50mm, these shifters should work.

More about these on my previous post; I'm still running this setup on my Passhunter.

They're compatible with all sorts of derailleurs and they look pretty spiffy with a pair of these.

In other news, the Cigne stems are due in soon, hopefully within the next month. We're thinking these will be $80 retail. As for the Polyvalent 4, we're still pretty far out and waiting on first prototypes. The time scale will depend on how these turn out and what we want to change.

Guys, $85!!!!! Sorry but I'll stay with my current 8 & 9 speed set up....

You'll spend a lot more money upgrading everything else to 11-speed than you'll spend on these shifters.

I will stay with 9-speed until I have exhausted all parts options. The challenge with 10-speed and 11-speed cassette is the gears are close together, which means changing gears requires very little cable movement, i.e. small shifter movements.

I've never ridden 10+ gears with friction shifters, but with the cogs all packed together as Rod Bruckdorfer points out, is it actually *easier* to shift? I mean if you pick a random lever position you are more likely to be near a sweet spot than with well-spaced-out cogs, no? Picking the actual cog you want would be more challenging, but I imagine there would be less trimming & adjustment with 10+.

Friction shifting with a 10 speed is basically impossible to mess up, minor touches yield quick and precise shifts, as with any friction shifting, you get a feel for the shifter position as they relate to gears as you ride and gain experience with the particular combo

I Just mounted the right side lever last night and honestly I can understand why you have a front and read lever, but I am not running a front derailleur so the left one is kind of wasted. It would be nice to save a couple bucks and only buy the right lever!
Also, I hope you are working on some options for Handlebar/Stem Mounting!? I can use the downtube shifter boss of my Atlantis for the time being, but long term I think mounting on the stem would be ideal.

I will report back once I actually get the chance to do some shifting, but right now I am waiting for my Cassette to show up! - Mas
