105 Di2 is here

The lack of servowave is disappointing. On the MTB side servowave is found down to the Deore level.

translation please? what's that?

Servowave is key to the "feel" and braking power progression of Shimano mountain bike brakes. Some people, myself included, swear by it for MTB. Others hate it and prefer the more steady progressive modulation of SRAM brakes.

I wasn't even aware it was a thing on the road side, but I'm not sure I would care as much for road brakes personally.

It's on 5800 w/ cable shifting, would be surprised if they ditched it?

I just can’t get over how heavy these mid groupsets are… geez!!!

At least it's lighter than Rival AXS. Not that that's an achievement, really.

I'm happy tech is trickling down and becoming more accessible, but that accessibility clearly does not extend to price. This groupset is so expensive even with an electronic "premium" factored in.

It is definitely a thing with GRX, and gravel is more road than MTB (unpaved roads, but still roads). I don't have a wide base of experience with disc brakes, but I have it on my Alchemy eRonin and I think the brakes are fabulous, the one part of the whole e-assist / DI2 / hydraulic disc brakes that took no learning time at all.

For me, the GRX discs feel just like a good set of cantilevers. And that's in stark contrast to the first set of disc brakes I tried, on a friend's e-bike: they felt like on-off switches or V brakes. My first attempt at finding the bite point with them locked the brakes and almost pitched me off. Perhaps it's no surprise he hated the bike too, and sold it shortly after purchasing it.

The claim being what??? its easier? its faster?

In exchange we swap the utterly simple index shift & add batteries,chargers,servos,micro switches?

Just wait until all of the settings for your bikes are stored in the cloud. That will, however, making shaking ones fist more apropos.

Have you ridden di2? It's mind-boggling good. I love it. And I am a Campy mechanical retrogrouch. I have a steel lugged bike with Campy Record mechanical...which I love... but also have a carbon wunderbike with 12s di2 and it's. really. good. press button, beep boop, shift. No adjustments. No cable stretch. No housing or cables to wear out.

It became a thing on the latest generation Ultegra and DA road groups. I agree about it on MTB's - it's great. I really like it on the road group also, solely because it reduces lever travel to contact by a lot.

I would be surprised if there is no rim brake support seeing as how it’s available for 9200 and 8100. The downside of running rim brake is the shifters are not wireless as they are in the DB version.

We’ve really been up charged on these group sets haven’t we? So, if you’re looking for mechanical is it Tiara or Lower then? Or just previous years used or NOS 11 speed?

I see a marketing opportunity for an old bike/retro 11 speed mechanical rim brake groupset. Not sure how big of an opportunity, but it would be nice.

The tiers all exist. 105 Di2 fills in the pricepoint below UDi2 12 (12spd Ultegra moved up quite a bit in $ over 11)

I think they will have a full mechanical 105 group, just not rim/Di2 option.

If this is the direction they are insisting on it would be nice to see them continue to produce a non tiered mechanical rim brake group of ultegra quality to keep people on the road who dont want such things. I'm sure it would continue to be a strong seller.

Man, the prices for these new groupsets are absolutely insane.

Anyone remember ~5 years ago when you could buy a complete 105 5800 mechanical groupset from Merlin Cycles for $385 shipped?

Or an Ultegra 6800 mechanical groupset for around $680 shipped?

Those were the good ole' days...
