Shimano 105 Di2

magicbastarder

i dialled in my ultegra 6800 three and a half years ago, and IIRC it has needed a single tweak since. it's my dry weather bike.

anyway, it'd be hardly worth the cost for saving the hassle of an annual adjust?

Thats just crazy money for groupset - For comparison I built a TT bike from scratch in 2016 was €1,429 fir Ultegra Di2.

Also,when I couldnt get a groupset during lockdown I ordered a Sensah Empire Pro for 260$ for full groupset including brake calipers, brakesm chain etc etc.

How do you find the Sensah groupset? I was intrigued by it. Tempted to use it to replace my Sora.

Am tempted by the Sensah stuff myself, have seen a couple YouTube videos on it and it doesn’t seem to shabby for a midrange option at a much lower price.

Never heard of Sensah. Thanks. I'm now going to spend most of my working morning hovering over the add to basket button.

For those of you interested in the Sensah groupset.

There's one or two followup videos, and I think there's a suggestion that buying components separately worked out better, or at least allowed for better brake calipers, which seemed to be the weak point

Sensha/microshift or something similar was the reason Shimano/Sram etc have to keep moving; and by that I mean convincing cycling consumers that they need the newest latest and greatest version of gear shifting. Corporations don't survive if they sit still.

Since 7400 was launched the refinement and improvements possible in a simple ratchet and pinion system accurately and repeatably adjusting a derailleur via a cable only had so much road. Once they hid cables they knew smooth shifting had already peaked for cable shifters.

To convince people they need the newest dura ace they came up with di2/wireless etc; to survive they need to keep doing that.

I'd be surprised if and when Tiagra goes 11 speed that it doesn't have a different pull ratio to 5800/6800/R7000 etc, that's what happened when they introduced 4700.

For the home mechanic or someone who tours or rides audax the reparability and predictability of mechanical systems has to be a high priority. I've had cables snap on very long events, but with experience you recognise the warning signs and can act before failure.

I don't care how reliable di2 can be; when it fails I'm going to be incapable of fixing it on the side of road or at home.

Mr. Cats

Saw the list price for Trek’s new Madone ‘SLR 6’ which I believe is the top of range frame with the new 105 7170.

€7,700

7.75kg

Jesus wept

magicbastarder

that's a lot of sevens.

but over 7k for a bike with 105, is just bananas.

Over 7k for a bike is just bananas

There’s a few bikes spec’d with it here

https://road.cc/content/tech-news/33-bikes-feature-shimanos-new-105-di2-groupset-294031?amp=

Cheapest one is the ribble endurance 725 which is a steel bike at £2499, an extra £1000 over the mechanical r7000 spec. Any of the standard AL frames and that are £3k plus for the lowest options

magicbastarder

maybe i'm just ageing, but my eyes are drawn to the Ti and steel ones.

though it's funny to hear a groupset costing €1.9k and seeing a bike with it, a 725 frame and ksyrium wheels retailing at STG£2.5k.

How does SRAM eTap compare? I see Canyon have an Endurace CF with Rival eTap for €3,000 whereas the CF SL Ultegra Di2 one is €4,150. Only difference is a around 400g less weight, the fancier seat post and carbon bars.

Didn't have any issues when using SRAM Apex on my last road bike.

Whatever the pros and cons they are certainly making it quite expensive to get a decent bike especially for casual cyclists who just go out for a bit of fitness on a more or less entry level road bike .

Mr. Cats

So if an alu 105 bike is 3.5k, it’s no longer the entry level for most I guess. That pushes 105 into the ‘upgrade’ bracket after a few years of getting into the sport.

It gets a bit confusing then what the point of Ultegra is.

magicbastarder

I guess it's a waiting game to see if they continue to make mechanical 105?

cletus

Will Sora become 10 speed at some stage? and Claris 9 speed?

Same here, never had to adjust until the cable frayed at the shifter about 1.5 years in (which apparently happens with Shimano Ultegra quite a bit (r8000)). Changed the cable, didn't even get any cable stretch and it's been 2.5 years now without any sign of issues.

Out of interest I looked at my bike online for prices, its just wrapped up, the last few at my spec were selling for €2k more than the price I bought it at. The disc version which is heavier and is still for sale is double the price. it is insanity.

I'll be keeping this groupset going for another few years before I change

alentejo

I defo think there is a place in the market for a decent cable and mechanical based group-set. It will add around 700€ to a standard bike of that ilk

magicbastarder

it'd be nice if shimano occasionally released new builds of older groupsets (though changing tooling over might be prohibitively expensive); and i suspect even a small outfit making retro groupsets would face very significant per-unit costs to manufacture them. e.g. dura ace 7600 is lovely and clean looking, but despite being old tech would probably be massively expensive to recreate in small batches?

I does what it says on the tin, shifting is single paddle, 1/3 click up, 2/3 click down Full Click 2 down. Once I got used to that was happy. As per one of the videos above, the brake calipers do seem a little less solid than Shimano, but I have had no issues with them.
