We were lucky enough to have a new 2009 Isaac Sonic on our stand at Cycle ’08 and it certainly created quite a stir. We haven’t ridden it yet – they don’t allow that sort of thing at the Cycle show – but here’s the technical lowdown. What Isaac are aiming for is a race bike that you can ride all day, that’s extremely light, efficient, robust, comfortable, oh and it’s got to have killer looks as well. The They’ve certainly succeeded on the lightness bit anyway our bike weighed 14.8lb (6.7kg) on the road.cc scales and no arguing it’s a looker too. As for the ride we’ll let you know asap.
It’s tough too – surviving trial by tourer on the road.cc stand when one over-excited visitor managed to drop a bike on it not once, but twice in quick succession (a memorable show moment for all who were there…). Isaac’s design philosophy places great emphasis on the strength of natural forms, all their bikes have flowing curves rather than lots of straight lines – they are all also true monocoques meaning that the front triangle is one continuous structure without joints or sockets. Isaac maintain that a curved one-piece structure allows stresses to be dissipated more effectively allowing you to build a frame that is both light and strong. All those curves look pretty good too.
So what’s different for 2009? The big difference is something that you can’t see and will hopefully never get to experience, improved impact resistance. We reported on this from Eurobike but all new models have what Isaac are calling Synthetic Sphere resin added to the pre-preg carbon fibre this was developed by Isaac in collaboration with a Japanese university. This resins is used in conjunction with various grades of high and ultra-high modulus carbon filament, supplied by Japanese producers Torayca and Mitsubishi Rayon, are used, with an attractive 3K weave in the visible layer. The lamination is made up of between five and fifteen layers of uni-directional pre-preg carbon. All Isaac frames feature a continuous, woven, visible layer. The Sonic employs a 3K weave. This has an important structural function in that it increases resistance to de-lamination and bursting in the event of an accident. It also protects the underlying structure from knocks and abrasions. More Sonic pics
The latest Sonic also boasts a new monocoque fork, shaped specifically to complement the Sonic frame, which incorporates a dual diameter steerer. The reasoning behind this, say Isaac, is that having a larger diameter to the steerer at its base gives increased stiffness and safety without a weight penalty. It also allows an oversize lower head set bearing to better deal with the impacts and stresses. Dual diameter steerers are becoming more common and are an innovation we’ve noticed cropping up more and more particularly on top-end time trial machines. An FSA Orbit Carbon asymmetrical head set is also included to complete the frameset package. This has high-grade stainless bearings and a carbon fibre top cap. COMPLETE BIKE SUPPLIED TO ROAD.CC Our Sonic was a 54cm sized frameset (48, 51, 55.5, 57 and 60 are also available) built up with Isaac ‘bars, stem and seatpost, Shimano Dura Ace 7800 drivetrain and a set of Lightweight wheels. You can buy any Isaac either as a frameset or a complete bike. UK distributor RBS offer a custom build up option or they can supply it to your local Isaac dealer to do the same. Our bike weighed in at 14.8lb (6.7kg) as shown. Two colourways are available. White with carbon detailing or carbon/black with silver detailing. Sonic complete bike prices range from around £2,500 to £6,000. The Isaac Sonic 2009 is available from November 2008 at Isaac stockists across the UK. Isaac Sonic 2009 frameset UK srp £1,599.00 Bike as featured – approximate UK srp £5,250.00 For more Isaac information visit www.isaac-carbon.co.uk Product info line: 01329 820890

@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'.
"Serious cyclist injuries down 50% and overall road casualties continue to fall..." This is clearly fake news, invented by the bearded, sandle-wearing, bike-riding hippies who don't even live in Wales. Everyone who lives there knows that the frustration and cost to drivers of having to drive at the ludicrously slow speed of 20mph is worth so much more than a few dead cyclists. I live in the Forest of Dean, near Wales, and we've been trying for quite some time to get the national speed limit roads in the statutory forest reduced to 40mph, and 20mph in towns and villages. In fact, I mentioned it in the pub tonight, and the reaction from locals was, to say the least, not enthusiastic. It is a human right to be able to drive as fast as you want, and anyone saying different is an idiot. With Local Government Reorganisation, I was hoping that the Forest of Dean District would merge with Monmouthshire and then we could adopt the Welsh speed limits, but it ain't gonna happen, so sadly, we have to remain in England.
@andystow That's pretty much how new roads are justified. If ten million motorists save ten seconds a day over the next twenty years, and motorists time is worth a lot, then you can justify spending £372m on the new roundabout in Gloucestershire. You know, the place where the locals think that a cycle lane will destroy their life.
@rbrtribble as the driver was out of his vehicle, thereby not making it a driving offence, and the cyclists was stationary with their feet on the ground, there was no more need for a helmet than if the encounter had been between two drivers who had got out of their cars, or two blokes in a pub. Maybe all of those people who fall down the stairs and hit their head should wear a helmet? I'll give you the benefit of the doubt, and accept that you were being sarcastic, but leave my comment for the benefit of those who think you were being serious.
@chrisonabike if flash-mobbing by female cyclists dressed in french maid attire is what it takes to help the roads be safer for everyone, then i think it's something we should consider lending support to.
