Electronic Gears?
Discussion
I was speaking to a guy that had them on his bike and he said it was amazing the speed and smoothness which it changed gears was unbelievable. There was no lag and no mechanical clunking.
But I guess you have to say that if you dropped two large ones on it.
However I can see the advantage of having it on a time trial bike as it means you can change gears on the hoods and the aerobars.

If you want to upgrade your groupset - http://www.probikekit.com/display.php?code=D0021
although this does seem good value as it's got the electronic groupset and it's quite a tasty build as well - http://www.wiggle.co.uk/p/cycle/7/Focus_Izalco_Ext...

only heard about these while watching prologue also. Without soundind too stupid, how are they powered?
They appear to be rechargeable, so you have to plug your bike in overnight. Gawd knows what happens if they run out when on a ride. Perhaps you get stuck in top. Or neutral.Do they have an emergency dynamo so you can keep them charged.
Di2 makes sense for TT bikes mainly. You stay in the aero position and don't even have to move your hands to the shifters. Just press a button under your thumb.

Whether 99% of riders would notice anything is subjetive...

I was really seriously thinking about it.
But I have one of those exposure rechargeable front lights and have often forgotten to charge it. So I can safely assume I will forget to charge this.
So what happens? I assume you just get stuck in the gear you have picked? How long do the batteries last??

It's at a premium at the moment, but performs well enough that I would bet we se it on most reasonably equipped road bikes within the next five years as the tech trickles down and bikes are designed around the system. I would certainly put money on the current 7900 Dura Ace being the last available with cables and an XTR variant for 2012. The batterys can do lots of miles with a charge, approx 600 so your not going to have a problem and could reasonably go smaller and lighter without issue.

FYI Mavic introduced an electronic gearchange system called first Zap, then Mektronic, back in 1994
It wasn't very popular as it was prone to changing gear by itself and battery life wasn't great.
Interesting didnt know that!It wasn't very popular as it was prone to changing gear by itself and battery life wasn't great.
But tbh we're now 16 years on.... my Sony Walkman (tape) could only get me an hour of playback now i get 4x on my Ipod.....

Awesome stuff, I demoed one on a trainer in a bike store.

The real reason they make sense for TT bikes is so that you can shift from both the extensions and the base bar - like when climbing or hammering out of the start or a corner.that focus is incredible value. cosmic carbone wheels and hte di2 grouppo are worth close to hte retail price alone, through in the frame, forks and finsihing kit and its a steal!...
havent used di2 yet, apparentrly shimano are already working on a 105 level version to bring it to the masses which may be ready in 2012.

Di2 is amazing, you really have to try it to realise just how good it is. It's a lot of money but as with everything in life, you get what you pay for.
It really is superb, the self adjustment to stop the inevitable "clackety clack" when on opposite rings is worth it alone.Gassing Station | Pedal Powered | Top of Page | What's New | My Stuff
