I struggle a bit with the idea that shifting under power is suddenly OK.
Ditto, I'm not sure if the sensation at the shifter is what prevents me shifting under load, it's all to do with the interaction between the chain and the sprockets I thought.
Am I the only pervert who takes great pleasure in executing a perfect shift under horrible circumstances? Finding those couple of unloaded pedal strokes on a steep rubbly gravel climb and somehow managing to get the shift in and keep climbing without any break in your cadence? Andy Schleck could learn a thing or two from me 😆
Oh, as for Di2 (AXS/Etap), anecdotally, i’m hearing that chains and cassettes are lasting a lot less time due to all the smashing across the cassette with no sympathy, especially on bikes ridden by people with no prior experience of mech systems (or no mechanical sympathy).
I'd like to know who you're listening to, Ultegra 8050 here and 8500km in I changed the chain at 0.5% wear and it's not just some fancy ass summer / dry only use bike, yeah it's a fancy ass bike but it gets ridden in all weathers.
My 105/ Ultegra mechanical set up (on two bikes) is smooth, precise, and needs very little maintenance. I can see the point of no cable and self trimming, but I'm far from convinced that it's a major benefit, say in the way moving shifters from the down tube to the hoods was.
Did people just ride a lot more and perhaps also have more physical jobs back in the day e.g. just a bit tougher?
Yeah, we were all miners and steelworkers back in the late 90s! 😀
(I tried to get an 11-27 cassette to put on my CAADX R800 and ride the Etape in 2000. It was almost the first time that such a low range cassette had become widely available for 'racing' bikes, and were like hens' teeth. It would have replaced an 12-23 or 25 cassette which came as standard on pretty much every road bike. I can't remember whether I actually got hold of one, or whether my suffering on Ventoux was because of a 23T lowest gear!)
Cannondale yr 2000 brochure :
Edit..bike radar says a full group set will cost 1700 quid rrp😳😳 you can but the current version for 700 and the rrp is only 900
Given price rises on everything over the last 6-8 months especially That £900 current would likely be £12-1300 anyway so the jump to di2 isn't as big a % as it sounds. It's still not small change though
The RRP for this is a bit steep, but I’d hope to be buying it on a complete bike under £3k.
I think outside of the cheaper brands it might be for the reasons above to be honest.
Ribble are listing the cgr at £2800 with 105 di2 so it's not impossible but I doubt you'll be seeing it on a trek specialized etc for South of £3.3 (edit: that or to get the price point they'll be fitting wheels with lead rims, isis bottom brackets cranksets that weigh more than your car etc.)
Specifying a Ribble using their Bike Builder 105 Di2 comes in at £600 more than 105 mechanical. SRAM Rival AXS is £100 less than 105 Di2, which figures as I guess Shimano would say those 2 groupsets are going to be direct competitors.

Assortment of shops, importers, team people.
Conversely, I have heard drivetrain longevity quoted as a benefit of electronic shifting, because shifting is so consistently precise.
SIS is as precise as anyone needs, perfectly aligned, every time (until the cable goes to shit), Di2 just adds higher load shifting and easier frequent shifting, especially with all the options for shifter buttons. I guess the whole multi/single shifting part of it will have changed though.

Also that mechanical will be last years model by the sounds of the above "no mechanical yet", so will be in a heavier slower colour.
In the GCN video he says he shifts once every 17 seconds on average. No idea how often I shift but it is nowhere near that!

Albeit quite a bit lighter than Di2.

I don't know, the most comparable thing mechanical has to a battery is me and I'm a lot heavier than even a full di2 group.
However unlike the rest of the 105 group I do have a slightly more grey colour for model year '23

It's actually quite alarming how much you shift over the course of a ride when it's in numbers in front of you - eg from a recent Sportive:
135km, 4hours 8 min, 1553m ascent, 955 shifts equals 3.85 shifts per minute. Thats not far of a shift every 15 seconds. This was a flattish (Bar the KOM section) and fast course so lots of small cadence adjustments plus in the wind/on the wheel, but still, a lot of shifts and a lot more than I remember.
10mile TT, 25 min, 48 shifts = 2 shifts per minute. Most of that time spent in 'puppy pose' on the tops of the bars. I think we change gear way more than we consciously realise.

Di2 Ultegra is only about 80g heavier than mechanical Ultegra, and that's with an extra sprocket...
Re: price - crazy legs has it - it’s far better priced in dollars or euro
Brexit pigeons coming home to roost
I’m guessing the OEM’s will lap this up

I've seen 2992g quoted for 105 Di2 and I think mechanical is about 2500g.
Mason have just put out a "preorder" notification for 105 Di2. They are quoting £3595 for a Definition 105 di2 which is £550 more than mechanical. So similar to Ribble's difference. Rival AXS is £3695.

Ug. People selling maintenance classes will be rubbing their hands together though, soon £60 or so to learn how to adjust your own gears will be the cheapest 492g weight saving you'll ever make on a bike 😎
Quoted weights for Di2 vs mechanical sometimes leave out (or are completely ambiguous on) cable inners and outers vs Di2 wires, which reduces the weight difference somewhat.
Downsides of DI2 only – unless you have compatible internal routing
I have electronic Di2 on the steel TT trike, cable down the underside of the downtube. It's not really noticeable and that's a yellow/blue rather than black frame. Electronic shifting is fabulous on a TT bike. The 105 looks great, but the TT shifters will not be 105, I imagine.
I thought it was funny that the only two cassettes available were 11-34 and 11-36
Can you have 1126 matched to 53-39? That would be pretty awesome actually. I did miss my 53 big ring in Mallorca on the hire bike, it had a 50 whatever compact.
