Re:

There have been issues with the junction box. It does not show up on the diagnostics....so mechanics would not find a problem.

Link?

No Link. Personal experience. Feedback from a Shimano main dealer after my friend Richard had a issue with flat battery's and FD not working as it should.
The owner mentioned that Sky were having big issues with shifting using the di2 and having issues with the diagnostics not working as it should mainly due to the exposure of the junction box " bad,faulty connections" , weather condensation etc and were not finding faults until they happened in mid race on a few occasions.
it would be one explanation why these faults are not getting spotted.

13 WT Teams on Shimano Di2

http://www.cyclingweekly.co.uk/news/latest-news/2015-worldtour-pro-team-bikes-guide-152997

if Sky (or any other Pro Team) were having "big issues with shifting using Di2" i very much doubt they would risk it, let alone use it

if the word got around amongst the Pro Peloton that Di2 was malfunctioning because of "exposure at the junction box" you'd see all these Teams back on Mechanical ASAP

I'm speculating here, but what about moisture ingress over time? There's been a few wet stages now and team bikes are usually washed after every stage.

 

[King Boonen]

Almost all WT teams are on Di2, so there will of course be more Di2 failures than anything else and as it's electric you would image water ingress would be the most likely, but I don't think there have been an increase if failures as to when everyone was on cable systems.

 

[JackRabbitSlims]

i'm not saying that none of this is possible

how long has Di2 been in use in the Pro Peloton? how many races, how many wet stages, how many bike cleans, strips etc etc
electronic shifting now on the mtb scene
surely a more robust, durable set up required to riding / racing in that environment?

a big company like Shimano pour plenty of time, money and resource into R & D and then all the testing before coming to market with something like this
quality control would also be top shelf here coming out of production in Japan
great reputation

imo i think someone dropped the ball (mechanic) and the knock on is huge

i doubt Shimano would be covering up a faulty product, esp at the tdf

just my thoughts / opinion

perhaps Ray's mate Richard down the local bike shop is ahead of the guys at Shimano and the tech's / mech's at the tour

again, if there is a groupset wide issue with Di2 at the tdf i would expect to see teams binning it and going full Mech....wouldn't you?

its and interesting discussion
lets continue it and hope more info comes to light

Nibs and Bertie and few others just wont use it. If you lose a race because of a computer glitch that somehow feels different to getting a flat tyre or doing a Schleck.
I can shift up quite a few cogs in a sweep using the paddle on my red to exactly the gear I want to be in.
I could do this with 7800 as well. I don't like pressing the button on electric shifting, it has a bit of a detached from the bike feel about it "clinical" It does work well but a bit soulless. I like the fact I can feel my way across the gears " sounds a bit wrong " You know what I mean.

Some interesting points here. The most likely scenario is a rushed mechanic, these guys have a lot on their plates and have to do a good job quickly.

Re: Di2 reliability, teams - especially WT teams - have excellently maintained equipment, it is expected to be running in as new condition every day. These bikes, despite doing major mileage aren't subject to the same type of abuse your average punter's bike can be. Team bikes aren't put away wet, they aren't allowed to accumulate layers of road grime, they aren't subjected to some crazy amateur wrenching, they don't get knocked around in garages/cars etc.

This means that your average shop wrench can often see flaws in a product before a team does, because the average punter isn't anywhere near as meticulous with the maintenance and care of their bike. Even though a team bike is ridden harder, it often doesn't get the same abuse.

not on electronic, but gives you and idea what happens to the race bikes post stage

tinkoff saxo aren't officially sponsored by shimano

FSA are rumoured to have an electronic groupset on the market by the years end
expect to see tinkoff saxo using it in 2015

alberto contador uses mech DA over electronic to save weight
lightweight alligator outer cables also used in conjunction to drop weight

They were meant to have their FSA gruppos before the Giro. I doubt that we'll end up seeing them this year, next year's race bikes will probably get them.

 

[JackRabbitSlims]

whenever it arrives, it had better be very, very good

riders use their favourite gear re branded from time to time (Nibali's saddle immediately comes to mind)

comedy gold to see Contador etc riding Shimano DA rebranded FSA if the stuff turns out to be less than impressive

i hope FSA work well under pressure
the engineers & designers, not the group set
well, that should work extremely well under pressure actually

Tiso brought out a 12 speed wireless quite a while ago ,,,,check it out, a lot of folks missed this one.

Tiso make some very nice stuff , I have used a few of their parts.

[JackRabbitSlims]

article was from 2012
never heard of Tiso or seen any of their product

if you're making a groupset for road or mtb use it needs to be at the very least as good as the current crop and at best, doing something that the others aren't in a much better way
good luck trying to catch up
needs to be on pro teams & riders
needs exposure

how long have shimano & campy been in the game
sram struggling to remain a major player and clutching at straws to produce something innovative that will create interest
fsa next cab off the rank to the market
really looking forward to seeing what they have to offer

It really went unnoticed. Plus Tiso are tiny compared to Shimano etc. They make more exclusive parts.
But say like Ax lightness etc are just to small to sponsor a big team and perhaps to much of a risk for a big
team to take. There are some great small company's making incredible parts but on a commercial level don't have much chance against the big boys and don't have the huge financial structure needed.
You do see some parts pop up now and again ,Froome was riding ax lightness wheels. Fab and the Schleck bro's were using Berner derailuers etc . The big boys have it wrapped up.

Nibali is on Astana and they are ALL on mechanical Campagnolo. EPS has a 'feel' absent from Di2, a specific requirement from the riders, that Campagnolo was sure to design in. Their levers 'click'. Di2 doesn't.

BTW-both EPS and Di2 are multiple shifts in either direction. shimano mechanical and sram are one higher gear at a time..but you know that.
