Isaac’s Joule has been around for a while now, it was one of the first of the new generation of full carbon monocoque time trial machines. Since it’s launch the Joule has spawned a mini range with first the Joule Aerotic and now the Aerotic Pro. For 2009 the original Joule frameset has beent re-designed in the wind-tunnel (and given a new name, the Efficiency) and there are various tweaks to the Aerotic. All of Isaac’s bikes get a new resin mix (whatever carbon weave they are made from) which, say Isaac improves impact resistance across the entire range. Top model, the Aerotic Pro, is basically a 2009 bike anyway and represents something of a departure for Isaac in the methods used to design it..
Up until now Isaac have designed their bikes using a mixture of computational fluid dynamics (CFD) to come up with a design and then tested and tweaked in the wind tunnel – the same approach Trek take. For 2009 though they have done things differently. The Joule Aerotic Pro was designed purely using CFD while the Efficiencey – the latest incarnation of Isaac’s original Joule frameset design, is a bike designed in the wind-tunnel. Interestingly, slightly bulbous head tube apart they are quite different looking bikes.
For 2009 the Joule Aerotic Pro is suppled with three seat clamp units giving a choice of positions and an XXS size has been added to the range. Frame, fork, headset, and clamps will cost £1,998. Claimed frame weight for the Aerotic Pro is 1380g for the small.
Sitting just below the Aerotic Pro, the Joule Aerotic gets a removable seat post for 2009 (a refinement aimed particularly at triathletes who travel with their bikes and find it tricky fitting machines with one-piece integrated seatposts into conventional bike boxes and bags). A simplifed materials spec over the Aerotiic Pro helps keep the cost in check – but both Aerotic modela are made from Ultra high modulus reinforced carbon 440 Gpa. Claimed wait for the Aerotic is 1450g for the medium and the and the 09 frame and fork package will set you back £1,599.
The Efficiency is an evolution of Isaac’s first Joule frameset and the emphasis here is on a high strength to weight ratio: claimed weight for the medium is 1250g making it much the lightest of Isaac’s aero bike range. Continuous developments over the last four seasons have included materials revisions, a new fork, internal cabling – and a revised down tube section to further improve aerodynamic performance. Apart from the bulbous headtube it is certainly a much sleeker looking machines than either of the Aerotics. That said, all of Isaac’s usual touches are in place: an Isaac monocoque fork wotj dual diameter steerer, internal cable routing, and an FSA orbit-carbon asymmetrical integrated headset. For 09 the Efficiency frame kit can be yours for £1,299. Coming soon… more TT bikes and TT trends More Isaac pics

The picture from street view clearly shows give way lines from the roads to the green painted cycle/pedestrian lane.
If I recall there is a cave or two along the route - perhaps they were sheltering from the heat in one of those having taken it for a Golf bunker?
“So if there’s a cyclist travelling down the cycle path at the moment, from this position I can’t see them because my blind spots are too big on the left hand side of the vehicle”, claims Hill. Well, there's your problem, right there...🙄
First impression from the headline that he's likely a twit. Then the detail he was expelled from Reform makes you suspect that failing even their low bar requirements he really is. Then he clearly explains his vehicle is unsafe for the highway because he can't see to give way when turning. Any collision he now has should have that video run out explaining he drove a vehicle he knew to be unsafe. Advice for motorists; instead of thinking that pedestrians and cyclists are low risk 100kg objects, imagine them as a 300 Tonne trains that will crush you and your vehicle if you cross into their paths. You'd give way to the train, so you equally can to the others.
I've had a brief look on Facebook, and Ed Hill (who now appears to be affiliated with Advance UK) seems to have taken some useful road safety improvements under his remit, including an initiative to help local pedestrians on unpaved roads, where the wider council won't help due to planning failures. Regarding the cycle path, I think this is linked to a wider misunderstanding about giving way at junctions and I'm afraid I cannot agree with Mr Hill's conclusion. Regardless of the suitability of the cycle path, vehicles should give way at the junction to both pedestrians crossing and cyclists. It seems to be a poorly understood rule among motorists where some believe they have priority at junctions like this, where they certainly do not. I once had a similar issue myself, while leisurely walking to Waitrose to buy some lunchtime fripperies. A driver beeped their horn as I crossed the junction, despite me having priority, and was shocked and apologetic when I explained I had priority. A polite conversation later, the driver departed, educated and updated on the rules of the road.
"A cycle lane that traverses the entrance to a side road in Exeter should be changed so that “cyclists give way to vehicles”, according to an independent county councillor" Newsflash: Bicycles are vehicles. Now what?
Bland and overcooked spaghetti
@mdavidford That would seem likely.
@StuInNorway Presumably they pulled out from the parking on the other side without paying any attention to the oncoming traffic / police car.
@StuInNorway photos taken a week apart. Ragebait. ;-)
