Ross Mitchell shows us the i-Shifter system. The i-Shifter employs an optimal shift sequence to operate both front and rear derailleurs simultaneously so that the overall gear ratios change at an even rate.
iShifter System
- Integrates front and rear derailleurs
- Even progression of gear ratios through the entire gear range
- Eliminates cross chaining and redundant gears
- Recovery shift is built in automatically to the system
- 12 gears total – all redundant gears eliminated
- Crank through gears really quickly
- Riding becomes seamless – don’t have to think about shifting up or down

Looks very interesting. I’d love to try it. Any idea on price and is it available to buy?
It remind me EGS system : syncro-shift : http://www.e-g-s.com/concept/index.html
And that’s more than ten years ago !
Nice idea for casual riding on pavement. Horrible idea for mountain biking.I predict bent chainrings.
really interesting idea here
well that would sort of defeat the purpose of having multiple front chainrings… one of the main REASONS is that you can skip gears very quickly; I agree with bearsquirrel, maybe if you ride bike paths this would be a good idea.
Shouldn’t you just buy a Rohloff???
“Shouldn’t you just buy a Rohloff???”
Are you aware of the weight and cost penalty of a Rohloff? Plus all the weight is on the rear wheel.
I see this as something for the casual rider / kids who have issues with front derailer
A great concept but in real trail situations when your using your triple ring trail bike to bomb down rock gardens,it’s nice to pick a ring combo that keeps your chain on.
What if you’re a wimp-ass like me and you WANNA jump into the granny cuz your heart is gonna explode?!!
Braaap!
Why are there so many ways to remove the human element from so many things? Is it really that hard to shift? For a 24 gear drive train, I teach people to shift like this- 1 on the left, 1-3 on the right. 2 on the left, 1-8 on the right. 3 on the left, 4-8 on the right. I even write it down on the back of a business card. If they find that too difficult, which happens far too often, I show them a single speed.
