Re Sram “reliability”

Whereas pretty much every Shimano issue has been rejected to someone not switching the charger on at night.

In Vuelta 2019, Shimano was already doing interference tests ... it is assumed that before and after too ................ and they will have everything very well definedTobinHatesYou wrote: ↑Tue Jul 27, 2021 4:56 am
Has there even been a report of radio interference causing reliability issues in a race? Sounds like FUD to me.

The option of wired with wireless failover if the connectors come loose would be interesting for the truly paranoid.
So basically would act as an insurance and with every insurance it carries a price/cost over it. Thus, as long as shimano prices a premium for that insurance im totally fine with it.TobinHatesYou wrote: ↑Tue Jul 27, 2021 8:36 am

Regarding the famous video of mollema... Really?? For every video like that someone can also easily find some other riding literally kicking their dura ace equipment. Are we 5 year old? "but my father is a policeman and will bring his policeman friends"
A pro rider will not care if its wired or wireless. Again, they are paid to ride. That's their comparative advantage and they better use it and specialize in it.
95% of pro peloton cannot distinguish between Shimano or Sram, imagine talk about wireless protocols, etc....Discodan wrote: ↑Tue Jul 27, 2021 6:31 amMaybe that should have been: Because most pros will still want wired for "perceived" performance/reliability
Agree that etap doesn't have a wireless reliability issue but pros can be a very conservative bunch, particularly when they don't have to route the cable
But they dont have to. Their are not pro mechanics. Their are pro cyclist thus they cycle.Alfus wrote: ↑Tue Jul 27, 2021 10:16 am95% of pro peloton cannot distinguish between Shimano or Sram, imagine talk about wireless protocols, etc....Discodan wrote: ↑Tue Jul 27, 2021 6:31 amMaybe that should have been: Because most pros will still want wired for "perceived" performance/reliability

(semi)wireless connection is recommended for hydro brakes 12s shifterspdlpsher1 wrote: ↑Tue Jul 27, 2021 2:00 amThere would be no need for junction A as junction A has become part of the RD. The extra port would just be used to connect to the battery. If the new rim brake levers are truly wired then there's little incentive for people to upgrade their existing rim brake levers. As for the existing hydro levers they won't be compatible with the new derailleurs which will add perhaps $600 to upgrade to 12-speed.
OOO- could you confirm if the rim brake levers are indeed wired?
(fully)wired connection is recommended for rim brakes 12s shifters (no A-junction)
I don't know if you can use them other way around
old tt hydro shifters ST-R9180 are compatible with 12s di2 (see here; no a-junction)
other old di2 shifters uses same chips, hopefully they will be not software blocked

Thanks ooo. If the rim shifters need to be fully wired, that would be a big miss on Shimano's part. Did they just not want to put in the work to design a wireless rim brake shifter and try to maintain the old design?ooo wrote: ↑Tue Jul 27, 2021 2:05 pm(semi)wireless connection is recommended for hydro brakes 12s shifters

I'm not sure what "recommended" means here - would there be an option for wireless, perhaps connected to a separate transmitter if the shifters themselves don't have?
Maybe they didn't see any further invest in the rim brake market and recycled the old rim brakes and STIs for 12s DA?harblhat wrote: ↑Tue Jul 27, 2021 2:32 pmThanks ooo.

I was going to comment on that...............
What is the use of a rim brake lever with wireless and recommend a cable connection? when the patents show rim brake levers with the wireless transmitter
