Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

So further away than the unit buttons?

yes...
your logic is commendable. i only really meant that from a visual point of view, it could well go there.

Mmm wireless. Much hot, so want.

Is wireless braking actually a possibility for the future? Car's have fly by wire systems so maybe it's not such a ridiculous idea. Although the notion of running out of battery mid descent could be interesting.

No. No car has FBW brakes. The failure modes are horrible, there is no safe way of dealing with battery problems, and the forces involved would require enormous batteries. Not going to happen.

And so long as we still have brake cables, the benefits of wireless gears seem rather marginal to me. If you're keeping the brake cables then attaching a single electronic gear cable to one of them seems less than onerous. Probably won't stop me from getting an eRed groupset once it comes out though...

Wireless shifting is fine, but braking? Surly not... You would loose the sense of modulation and wouldn't be worth the weight saved.

so SRAM wireless...

we're going to have to charge 4 batteries and have 4 potential different points of failure while out riding?

they will be wirelessly charged too

Apparently, Garmin is working on electronic steering - it follows your route, so you don't have to worry.

I look forward to electronic motors. Wasn't Cancellara testing one out a few seasons ago?

Sram electronic...

They can use electronics to compensate for their weak as piss deraillers.

Good move by SRAM. Wireless was the logical next step and it looks like they're ahead of both Shimano and Campagnolo.

If it works. They don't have a good track record with groupset debuts.

Shimano had to make everything for the first gen Di2, the second gen stuff and EPS use commercial-off-the-shelf (COTS) actuators/etc.

I would imagine that SRAM is buying in all that stuff, which both introduces and removes a risk of failure, as it were.

They still have to rememeber to have enough metal in the cages to actually move the chain, regardless of what electronic voodoo is behind the scenes.

When was the last time you had a battery fail?

by fail I mean run out of charge

and so... every day on my phone?

You do realise electronic groupsets have a >1000mi battery life, don't you? You'd have to be an idiot to run out.

yes but it has been known to happen, and presumably likelier with four batteries needing charged. probably not an issue as long as the charging is simultaneous

Only two batteries will need regular charging, and you presumably have the benefit that if the rear fails you can use the battery from the front

That would be smart

It does happen - I've seen it first hand several times.

Up to 1,000 miles? really? if that were the case, then it might explain why some people with Di2 end up DNF long audax ride.

Where were you in maths Ed?

">" does not mean "up to" it means "greater than", ie. "at least".

Obviously depends on how often you change gears.

Meh. You need to remember to charge Your garmin every 20 hrs anyway. Otherwise why ride?
