Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

Have you tried the 11?

Now Tiso launch an electronic groupset;

8, but I think the soft clutch is in both.

This.

I don't know if there's any internal gear hubs out there that doesn't feel soft/indirect, even the Rohloff.

Ooh new erectric players.. fight!

My latest retrogrouchified Bicycle Quarterly issue have an electronic shifting article with two high end ti bike both equipped with Di2 and EPS.

Going to read it and see how it is.

That Tiso is not going to be cheap I'm guessing based on the usual cost of Tiso parts

at least it looks cheap.

I like the look of the Tiso.

Not convinced wireless is an advantage, as your always going to be sat on the bike when you want to change gear. So theres little reason not to run cables.

Still. Maybe you can buy the remotes, and change oponents gears while racing. I can see the advantage in that.

Moving from an SRM with a wiring harness to an SRM without has convinced me that wireless is much more convenient.

Probably not a view I'd have agreed with without trying it, however.

But- just attaching the components where you think they should go and it working is much better than working out your cable management between each point, applying U channel stickers, zip ties, cable wrap and electrical tape.

Although in this instance it's a bit pointless as you have to power both mechs from the single, large, battery pack.

I guess you could have a tiny battery in the rear mech. charged via an induction system. Using small spoke magnet in line with a magnet on the lower pulley of the mech when in lower 1 or 2 gears.

Maybe a similar arrangment using the motion of the cranks could give power to the front.

Thats if anyone new how magnets work.

How much juice do you need?

No idea, from memory it's a 7.4v Li-ion battery, mine lasted for an entire year.

Apparently the front shift is much more energy intensive than the rear, so if I'd ever used the inner ring that lifespan might have been reduced.

Function > Form .. it's an artisan product

so if I'd ever used the inner ring that lifespan might have been reduced.

I was thinking about the same set-up as those Reelights. Probably not much power to be had. But maybe enough to trickle charge a small battery. Probably not really a marketable idea for the top end roadie crew. But I reckon it would appeal to electric alfine users.

I think you are setting your horizons too close- you are a chemist are you not?

So, work on a carbon fibre/Li-ion sandwich material from which to form the frame and wheels, said structural-battery composite to be used to power the electrical accoutrements and to be powered by the hub dynamo/regenerative braking, and to be able to direct power to the drivetrain as needed.

Then make it look cool and sell millions.

10% please.

You've fucked your patent app already. You've discussed it. It's now public.

Polymer chemist specifically.
Wasnt really a serious idea. It came from a days browsing snow biking kit, and a conversation with a mate in the UK. The kit was....

Electrically heated gloves;
electrically heated boot in-soles;
electrically heated water bladder;
Cycle computer with GPS;
the electric alfine; and
and a powerful lighting system.

Maybe I should have had a massive Li-ion battery built into the BB area of the fatbike. That itself was connected to the rear hub for charging. The charging mode being selectable. So you only used it down hills. Riding on snow gives enough extra drag.

If I get this Yumeya cage to run as Wiggins did with an XT 11-32 cassette will I need to run a smaller pulley in order to clear the largest sprocket?

And, thinking about it, would that cage work with Ultegra Di2, or is it only compatible with Dura Ace?

When's 2013 Di2 going to be available to us plebs?

Have a look at this .. Wayne Stetina is Shimano USA .. Worst case I would have thought simply changing the B screw to a longer one and the top pulley to a 10 tooth would give clearance for 32t based on this.

Thanks Oswald, that is very interesting. I am intending on 36/46 and 11-32 for reference.

Scherrit was working on a 2013 Di2 bike last night.
