Shimano 6700 Shifter

I have a bad RH 6700 shifter and need to replace one or both. My question are there any upgrades, or other group sets, that will fit my derailleurs?

Thanks

Dave

5600, 7800, 5700, 7900, are all compatible. Microshift and Sanseh also make compatible shifters.
4700 on the other hand, is not compatible, even though it is also 10 speed.

What do you mean by bad? I've had a couple of Ultegra shifters that didn't release or engage the internal mechanisms. However, a flush with WD40 (to clean) followed by a spray of Boeshield T9 (to lubricate) worked wonders.

Also, Gevenalle shifters. A different type of brake shifter but very durable, less expensive than most of the others, easily repairable and extra parts available, can be made to work with 9,10,11 speed cassettes (with the proper other drivetrain parts of course) by changing out the thumbshift piece and I Imagine 12 speed will be available at some point. Check the video. Some love them, some don't. Shifters – Gevenalle
First try MudPie's suggestion to flush and lube.

they are $209. Much more expensive than Microshift R10 brifters. Why would anyone prefer these over brifters anyways?
Also instead of having the shift levers just pointing down, Gevenalle should make the levers extend both up and down, or maybe 6 o’clock and 3 o’clock. That way you can reach the shifter either with your forefinger or your thumb and there is no awkward reach-around.

Mudpie, it will shift to the large cassette, but will not let me go back down. I pulled it off and when I push a small lever, it will work fine. I have yet to take it apart and investigate the reason maybe it is has a broken spring not pulling it back. Sorry for the lack of properly identification of the parts.

It's gummed up. You need to soak it in WD40 and lube it as already stated.

Based on your description of not shifting down, I believe the internal mechanism is gummed up with old grease and dirt. The flush and lubrication should be a cheap and easy fix.

Check out this how to video: the mechanic used White Lightning Clean Streak, but I've used WD40 as a solvent and flush. Also, the mechanic dabs on grease to the pivot points. I've never added grease and the application of the Boeshield (dry lube and protectant) was sufficient for me.

In fact, this video specifically cites your problem of not being able to shift to the smaller cogs.

Do not try to take it apart. No user serviceable parts inside. Flush it out and relube it. If that doesn't work and your cables and casings are good and properly installed, THEN you need a new shifter.

All, thanks for the advice as it is soaking in WD40. I have attached pictures of the lever I push (at the end of my knife point) to get it to shift back. Once it is pushed back, shifts like a charm.
