did you watch the vid?

just did and it's changed my mind - they move much better from one position to the other than I'd expected.  Nice invention!



whereas this: http://wattagetraining.com/08bikes/daRound2Contols.jpg

(from one of the comments below the video) is just asking for trouble!

Absolutely the same as my response!

My first impression was "utterly stupid idea". Then I watched the vid.

That kid has a future as a design engineer.

I still have doubts about the strength of those hinged joints.

That's my worry, though i haven't been able to watch the vid yet...

I don't see how the bar end shifters and brakes would cope with that moving
Apart from that it looks pretty sweet

Looks interesting. Therefore also probably soon to be non UCI legal.

Already UCI illegal. Rule 1.3.023 specifies that TT/pursuit extensions must be "fixed".

Quote

1.3.023 For road time trials and the following track events: individual and team pursuit, kilometre and
500 m a fixed extension may be added to the steering system; in this instance, only a
position where the forearm is in the horizontal plane is permitted. The distance
between the vertical line passing through the bottom bracket axle and the extremity of the handlebar
may not exceed 75 cm, with the other limits set in article 1.3.022 (B,C,D) remaining
unchanged. Elbow or forearm rests are permitted (see diagram «Structure (1B)»).

Interesting idea though.

Also not legal for CTT time trials - bars must be a minimum of 35cm width.

I thought about something like this a while back, but couldn't work out how you'd make the hinge strong enough. Then I realised that there's not a chance in hell that it'd be allowed by any governing body!

The kid who designed it does Triathlons. Their ruling bodies seem to allow anything  ::-)
