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

@Boopop I think every cyclist has stories of being lit up like a Christmas tree, and all the works, yet still having a SMIDSY moment
@Rendel Harris I would’ve replied to the driver, “Who said that? Is there anybody there?” 🙂
So they're kind of bossy and won't let others get a word in?
@DrG82 I think it was well implemented overall, though that is because I agree with the basic point: the speed limit where vehicles interact with pedestrians etc should be 20mph* by default: 30mph can be considered as an exception (e.g a major road with significant mitigating infrastructure, controlled crossings and so on). Some Welsh local authorities have been keener to create exceptions than others for sure. Here in Bristol, we have had widespread 20mph limits for around 15 years. The only downside I saw is that I got used to driving at 20 and would find myself doing so where the limit was 30 in other locations, to the annoyance of drivers behind (though perhaps the relief of pedestrians in front) *There was once a substantial UK report that found the default speed limit should be around 10mph to ensure that pedestrians are not killed by drivers. That seems a long way off.
@slc I wouldn't say that the Welsh government got everything right. They applied the speed limit changes uniformly, without considering exceptions, and have since back tracked in many places. This has been a massive waste of money.
Yelled at by a driver just last month, "It's farkin' dark you farkin' twat why are you riding around wiv a black coat on? You're farkin' invisible!" To be fair, I was wearing a black jacket - a Proviz commuter jacket which is covered in their unparalleled reflective details which, as I know because Mrs H wears the same model, can be seen from hundreds of metres away. He also overlooked the fact that I was wearing a fluorescent yellow helmet, fluorescent yellow gloves, had a rear red light on the helmet, two rear red lights (one strobing one solid) and three white lights on the front (one strobing two solid). Apparently all he could see, or supposedly couldn't see, was the black jacket. They used to be an old joke about "invisible" stealth planes being rubbish because the Russians would be saying, "There aren't any planes about but there's a little guy in a sitting position at 50,000 feet..." - must have been confusing for my chap to see all those lights, reflectives and bright gear apparently going down the street of their own volition.
Another reason to avoid Terry's, which is a pretty crappy overpriced place anyway and dreadfully hipster (there's a sign on the wall that says something like "when you eat at Terry's you're not just a customer, you're a member of a very exclusive club" - thanks but I just wanted coffee and beans on toast). I'd advise anyone in that locale to try the splendidly named Giggling Sausage cafe directly opposite, better food and coffee, cheaper, better service and fewer hipsters, you can enjoy watching them queueing like sheep to get into Terry's as you dine.
I wondered if parking in a cycle hire bay was against the law, so I googled it: it isn't unless there are road markings prohibiting parking. But, this little gem came up 'Obstruction: Even where a specific bay type might lack a dedicated motor-traffic prohibition, parking a vehicle in a way that blocks access to cycle hire docks, footways, or causes an obstruction is an offense.' Report it to the authorities and demand action. Don't patronise the place, obviously. And leaving rubbish reviews is definitely out. Absolutely, definitely out. Very absolutely definitely. Out.
".....dark clothing “has been deemed a contributing factor in many fatal or serious injury collisions involving pedestrians and cyclists” No. The dark clothing is not a contributory factor, the only cause of the deaths and injuries is drivers failing to observe. The list of police organisations above shows that motornormativity in the police is institutionalised, and just as rife as it is in the rest of society. The question is, how do we get them to change? Make all police ride bikes? Show them films of collisions where perfectly visible cyclists are mown down by drivers who weren't looking? Show them pictures of cyclists literally dressed up like christmas trees by are still hit by dumb drivers? The clincher might be the picture of the police car, festooned with hi-viz, after it had been hit by a driver.
@mdavidford the standard practise is to ignore the consultation, start a petition, complain that the council doesn't listen to the public, and get your picture in the Bournemouth Echo with a headline 'Drivers fury at new cycle lane', or 'shopkeepers anger at lost parking space'.
