Which Groupset?

But is there a powermeter in there too?

No, forgot they were after power meters!

Triple cranksets with a power meter built in are pretty rare. I only have one.

Anyone else think R8000 is fucking awful/had multiple issues with it?

I am really disappointed with it, especially after putting 6800 on my winter bike and it being faultless through a Scottish winter with little maintenance

in a 1000 miles commuting/lanes in London R800 has delighted me with

• Both calipers piston seals failing (common fault appaz)
  
• Left hand Brifter failed completely
  
• Rear disc warped, just because it fancied it.
  
• BB give up (not gs specific but annoying)
  
  

It also feels very flappy, cheaply made and indirect on shifting (compared to 6800, not campag), swapping cables hasn't changed this either.

I will say though that the front mech is an improvement over the 6800 though.

Aaah that feels better

rant over

Been happy with my Di2 version, particularly shifter hood size.

However the hydraulics have been an absolute pain to get right Manufacturing quality is a bit poor had to warranty my shifters as the 2mm bleed port rounded off.

I get the feeling they scrimped on the manufacturing.

Even the hoods seem to scuff up easily......

ah well, Etap on everything from now on :)

Any reason to use something other than Shimano jockey wheels in a di2 derailer?
Are there any smoother or more durable options out there before I shell out on Shimano parts?

Ceramic speed? Because you are made of money!

Because you are made of money angry hangovers and DVT!

Am I rite?

Hope / Kogel / C Bear all look nice, alu too so may last longer than the composite ones.

To go through your experiences, the calipers is not uncommon with all of the Shimano one, so the fault isn't just down to the R8020.

The left hand shifters is again, not uncommon which is due to the design (Tiagra 4700, 5800, etc. have similar issues).

Disc warped, not uncommon again, more suspecible with 140mm rotor, I didn't find the latest rotor to be decent, as sometime they squeal a lots, fitting a normal centerlock rotor sufficent.

And lastly, the BB is always hit or miss, depending on the frame (not faced properly mean it's more likely to wear out sooner than later), I'd just fit the cheaper BB on.

Incidentally, your experience of 6800 is pretty accurate, for some reason they were the most reliable Shimano 11 speed groupset insofar.

Maybe I was spoilt by my first road Shimano experience being 6800 then.

I have had XTR, XT and SLX on mtbs and they have been faultless.

I just won’t by Shimano Road groupset again, especially if you are confirming they are relatively common faults.

What about the barrel adjuster on the RD-R8000???

This happens on all series, from R9170 down to R8020.
Problem is that Madison still doesn’t stock the replacement. We have like 20 of them in back order just in case.
That bolt is seriously made out of butter!

Still, best hydro groupsets so far IMO

Couldn’t get one out and had to warranty whole shifter!

Luckily always managed to remove them with the old “grip paste+bigger torx key”.
Verdict is that bolt can be only removed with a brand new and high quality allen key (obviously not a ball-end one).

TBF, Shimano are the biggest and most commonly used groupset out there, so failure are more likely to happen.

To put it in presceptive, i never had a Campagnolo groupset failing simply because I did not service/build many bicycles with Campagnolo in comparison.

SRAM is in-between, slightly more common than Campagnolo, yet do get some warranty issues (even eTap have warranty issues).

I realised I made it sound like it a big issues; it's not, it just the large number of part = higher chance of running into a faulty one.

That bolt is seriously made out of butter!

It is, and way too small, I send one back to warranty and they return it with a different older style bolt.

I actually purchase an allen keys set that are only to be used on components such as these due to the higher chance of rounding the bolt.

Tried this too. Ended up snapping a reverse threaded stripped screw extracor in it.

I think it is a big issue and if what you say is true, then it’s a real shame.

The volume of sales shouldn’t matter, their manufacturing should. Madison are pretty slow on the warranty guff as well. If they know something is going to be repeatedly shit, they are daft to release it.

I pretty much used to ride Campag exclusively and found it well made and robust. It only went to shit when the 11speed came out and it was obviously (to me) manufactured far more cheaply. It kept failing, I got it warrantied, I got bored and went back to 10speed Ti Record.

I only bought Etap because when my Eastway arrived it had 10s apex on it and over the 5years I abused it it never missed a beat. Etap hasn’t so far either.

Basically I’m just pissed off with the groupset and its all in the eye of the beholder anyway.

Someone will get a bargain on here when I flog it anyway 😂

Interested as to how good etap is. I'm tempted on a new build although have (older) Shimano hydro di2 at the moment and it is pretty good... Should I take the plunge? Will need hrd as I'm going discs; are they as good as Shimano?

I have the rim brake version, but overall it’s excellent. I also have no experience of Di2

Set up is quite straight forwards on Etap if you take your time and since then I haven’t had it miss a beat.

I used it on Paris Roubaix with silly carbon chainrings and it performed faultlessly. Shifting is instant and positive and most importantly, the LED on the rear mech looks cool at night

Instant (or not) shifting was my biggest worry! That and whether hydro brakes were as good... I'll see how my budget looks when it comes to build time but I'm very tempted

I have them on the TT bike where I'm chasing seconds. I'm not going to wear out £400 jockey wheels doing silly ultra shit.

Much closer to the truth but you forgot 'kebabs'.
