1st Gen Campagnolo Ergopower EC-02RE CG G-Springs

So the internet doesn’t have much about the G-springs in 1st gen Campagnolo Ergopower EC-02RE CG Record shifting brake levers, so I’m writing this in the hope that it may help the very few of us that persist in using outdated components.

This is the said right side lever:

There is plenty of info online about how to replace the G-springs, so I won’t go into that, but here’s what it looks like when it’s pulled apart:

See that round bit fourth from the right? That holds the G-springs. This is what it looks like in the lever when you first uncover them:

You don’t really need to pull it out, but it is a good opportunity to give everything a clean. Notice the G-springs at 12 & 6 o’clock:

(Also notice the G-spring at 6 o’clock is kind of flatter than its neighbour, hence needing replacement.)

Now, if you rushed out and bought a set of right lever replacement G-springs, you’re in trouble; they don’t work:

Notice the G-springs at 3 & 9 o’clock…which is wrong. What you need to do is buy left lever replacement G-springs for your right lever. I thought you may be able to turn the round spring housing bit upside down, but then the G-springs foul the pins that hold it all in place. Here are the original right lever G-springs on the left and a pair of replacement right shifter G-springs on the right:

Now, I’m not sure if mine are an anomaly, but I suspect this is the case with all 1st gen shifters. WestToastPete’s EC-22RE CG Record Carbon shifters were correct in that the right lever replacement G-spring fitted his right lever. Not sure what happens with the model in between; EC-12RE CG Record. Why they had one way then changed it is anyone’s guess.

I also suspect my left lever would require right lever G-springs, but for the moment it’s working fine so I’m not going to find out anytime soon.


(Also thanks to Asher for supplying parts and Pete for helping me through the disassembly process.)


I’m not a Campag user, but this is an awesome resource. Sticky perhaps mods?

Could it be that both were rebuilt previously and the right spring and holder went into left and vice versa for the other side or may be at the factory or do the only work in each side?

The pins are part of the body itself, so it can only work this way

They are Italian threaded

this is bringing back horrible wrenchy memories.

Update: so after reinstalling the lever, threading the cables, re-taping the bars, adjusting the rear derailleur and brake, I took it for a spin and didn’t have any problems in the smaller sprockets, but it wouldn’t hold gear on the larger sprockets; just kept slipping down to mid-range. Funnily enough, in the workstand it seemed to hold position okay, but if I grabbed the cable it would pull out of gear from the shifter, if that makes sense.

So after a counseling session with WestToast, I am going to install some Chorus Ergo levers I have lying around, and I’ve already replaced the G-springs in both levers as to eliminate that from any potential problems.

So in relation to the above posts with backwards G-springs, possibly Mr Campagnolo realised that the 1st gen levers sucked so changed the orientation to overcome that.
