Wireless


University team develop wireless braking system for bikes

...and it'll only fail three times in a trillion.

FS: PowerTap 2.4 wireless, on Open Pro wheel, Shimano freehub, Complete setup £600

Hi

I used to spend more time training and racing than just "riding"

I've seen error of my ways and the training aids are up for sale.

I have a 3,000mile only PowerTap 2.4 wireless model, alu/carbon hub. cadence, power, HR etc etc.

Used one summer and one winter training not seen proper use for a year now.

The wheel has seen little use as I race mountain bike XC so was only used a couple days a week as part of my power intervals.

Di2: in defence of the wires

Everyone of a certain age remembers the Fisher Space Pen, a multi-million dollar project to create a biro using pressurised ink that would work in space. And it did. The irony, of course, was that normal biros don't stop working in space: the ink is drawn down by capillary action, not gravity. The moral? Don't spend a big wad of cash developing something new when the original doesn't need improving.
