I used to ride Campagnolo mechanical. After building my first EPS bike, I put my mechanical only Time RXR up for sale.

I dont think i could go back to mechanical for my personal bike but I certainly appreciate the fact that there are those who still do.

If I ever venture down the disc rabbit hole, I would get H11 EPS

Ive never used electronic and I’m scared that if I ever do, it will force me to spend more money and never go back to mechanical....
First bike after 14 years off came with D-A Di2(9050). The next two have eTap. Mechanical can bite me as I'm never going back.

I'm on DA9150. Added some climbing switches below the top of the bars. No matter how little purchase you have on the buttons, whenever you can reach them, you can shift. No force needed, can shift from any hand position now. I also like the full synchro shift for the same reason. Big buttons do rear derailler, only need to shift front directly at the crest or bottom of a hill. rest all taken care of by the system. DA has some extra buttons that can be assigned to tach functions so one can control that on bumpy sections or while cornering without taking hands off.

I’ve been through all generations and won’t go back; 7970 was good, 6770 better. 6870 again step forward and current generation is just unbelievably good. I have 9150 at the moment and plan to change my ST-RS785/6870 to R8070 on my cyclocross for next year.

I also have the climbing switch and I cannot live without it. With it I can shift effortlessly without even moving my hand while climbing. I just use my right thumb for an instant gear change. People say this switch is big and ugly. But when you're going all out on a climb no button can be too big, haha.

One oddity I can never figure out is why did Shimano put the wire exit on the left side when 99% of the riders put the unit on the right side of the handlebar :noidea:

I think the buttons are programmable so that doesn't matter?

I don't dislike electronic drivetrain that much, but I'm using the mechanical now, because I have little reason to change it.
The only merit of electronic drivetrain I think is automatic trimming, but It seems that the price difference is too much for just that one merit.
In addition, I don't like systems which needs battery charge. I rather have interest for news about Rotor's Uno than Di2 or Etap.

The buttons have different shapes to them and it's designed for a right-handed rider and mounted on the right half of the handlebar. One cannot turn the unit upside down and reprogram the buttons. The wire should exit from the right and be connected to the right shifter. Currently the wire has to make a U-turn which is dumb. Other than the wire direction the unit is well made and very functional. The big button are easy to press even with big, heavy gloves.

Electronics really makes sense on the TT bike and the cx bike. On the road it sure is nice, but not really necesesary. I have two identical roadbikes, one with 9070 di2, and one with 6800 mechanical. I enjoy riding them both, and when I’m on the 6800 mechanical bike, I forget all about it being mechanical after 2 minutes. I don’t miss di2, when I’m without it. But I still enjoy it on the di2 bike.

I remember being at a bike show when Shimano first introduced di2 . I gave it a go and it was very good. The thing I don’t like about electronic shifting is that it makes me feel unattached to the bike. It does not feel like I’m in control. I’m relying on a motor to do the shifting so for me it loses a human element. This is just my opinion and I admit it does work very well but it’s just not for me.

I’ve had 9070 for a couple of years on my nice bike, run mechanical on everything else I own. There’s nothing electronic can do that mechanical can’t but everything thing electronic does is just that little bit nicer and crisper. It all adds up to an overall better experience, whether that’s worth it or not is a personal choice. For me I wouldn’t go back now.

I upgraded to di2 2 years ago and it was utter bliss. But I just started riding mechanical again and so long as it's set up correctly, it's flawless too. Buy what you can afford. If you have cash burning a hole in your pocket and you want etap or di2 - go for it.

I had a weird transition over to electronic. I've always used Shimano mechanical, and decided to switch over to sram Etap and its much different. sram Etap so far is okay, I guess im not necessarily impressed other than the fact that there are no cables, speaking of cables, I feel like the mechanical groups give you cable feedback when shifting, which helps with shifting smoothly both on the front and rear mechs(which I miss). but this is just my opinion.

Try going back to a bike with no index shifting if you want to feel attuned. I'll take a little detachment any day over old tech.

are programmable, i have reversed the mode of change that comes from series, if desired, can be programmed for chainring change
