Rear gear shifter on the left?

[popcorn_skollie]

The answer is simple...

 

just get a whole new bike! (Like a Trek Ticket SS or a Nukeproof Rook)

 

Then you can mount the shifter on your downtube

Nuke Proof Rook

 

 

I see this as a win-win!

 

Not only will allow you to shift with your left hand...

But it will also improve your tail whips

Or... if you're not into spending another 20k+ on a new setup, but you don't mind going all old-school-10sp-racer when it comes to your shifting, maybe you can just Macgyver something for your shifter to mount to your bottle cage bolts (easy enough if you're running X0 or X9).

 

Otherwie, like others said, Gripshift is your best option.

 

that is so sick... the nuke may have more travel but I'll take the trek if I had the choice. I haven't seen a dual that managed to line up the slope style of a dj frame so perfectly.

Old XT Dual Control "top normal" levers might work. They shift by moving the brake lever, somewhat like a road STI and they don't need thumb pressure. Second hand ones go for a song since nobody wants them anymore.

i dont think gripshift is an option, if memory serves SRAM use a 1-1 ratio where shimano use 1-1.1.

i have no idea what that means in reality but i suspect it is the distance each click moves the derailleur.

there was a thread a few months ago about offsetting the shimano gears to work with SRAM shifters or something like that.

I'm very inexperienced. But if there's one thing I've learned from a few upgrades, its that in the rear, sram and shimano shifters and derailleurs parts are NOT compatible. Or at least, not meant to be since they have different indexing systems. (I'm sure a few mad scientists out there have managed to make it work in certain cases though) Sram have however made a line of shifters called 'attack' that came in 8 and 9 speed some time back. They were entry level shifters that were meant to work with the shimano derailleurs only.

 

Anyways if it were me, I would run a single ring upfront and go the gripshift route for the left side of the bar. You wont need to run a longer cable as you are simply switching sides. its also way easier to become accustomed to shifting in this way as apposed to fiddling with your thumbs or fingers with a shifter which is either going to be the wrong way round or upside down

 

Edit: I forgot to mention. Shimano have a line of gripshifters called revoshift. So sram are not the only ones. its worth looking into.

 

That is correct DaddyG

 

Most SRAM 9sp (with the excemtion of the Attack range) and all SRAM 10sp (AFAIK) have a 1:1 actuation ratio.

 

As for the Shimano, it's only their 10sp that have that 1:1.1 ratio.

 

And SRAM and Shimano FDs are inconsequential.

 

So the trick is a SRAM 9 or 10sp shifter on a Shimano 10sp RD with a bit of spacing (to get the ratios closer.

 

I ran a 9sp X0 shifter on a 10sp Saint RD, with some spacing, for Sani last year and had no issues.

 

But if the OP is running 9sp Shimano then this trick (with grip shifts) won't work.

 

I may have found the solution, a bit pricey, but may solve my problem:

With this lever, you use the brake lever to adjust the gears.

 

 

As for the dual-control levers, these won't work 100% as they're not flip-flop. So no matter what your brake orientation, the right hand lever is still for your RD, and will have to be run upside down to be put on the left. Not work the money in my opinion.
