Ridley launch a brand new Dean Quick time trial bike at Glasgow World Championships
[ad_1]
Ridley has introduced the arrival of a brand new iteration of its Dean Quick time trial bike. The Dean has been Ridley’s time trial providing for a number of years and the model has now launched the most recent model through the Glasgow World Championships the place it ought to see motion within the time trial occasions.
We noticed Lotto-Dstny riders Victor Campenaerts and Thomas De Gendt driving what regarded like prototype Ridley time trial bikes on the Critérium du Dauphiné through the stage 4 time trial. We assumed the brand new bike could be a brand new model of the Dean with Ridley’s announcement now confirming that. Caleb Ewan was additionally noticed driving a prototype Ridley street bike at races this summer time together with the Tour de France.
Ridley says the brand new bike has been developed from the bottom up utilizing CFD (computational fluid dynamics) evaluation and wind tunnel testing periods. Aiming to attain the least drag and most velocity while adhering to the related UCI laws.
We now have seen a whole lot of new and completely different body designs and shapes because the UCI revised its 3:1 rule which pertained to the size and width ratio of sure parts. The brand new Dean Quick is not any completely different. The up to date 8:1 ruling in place now implies that in a nutshell, riders can profit from extra aerodynamic (and visually extra putting) body designs.
Elevated length-to-width ratios permit sure parts to be elongated enhancing aerodynamics total. The model says compensation triangles have been used within the bike’s design to attenuate drag. Ridley cites the bike’s deep head tube profile as a very good instance of this, the deeper head tube form may also help remove turbulence behind the top tube of the body.
In line with Ridley, CFD modelling was used throughout growth to determine efficient body designs that may minimise drag at round 55km/h or 35mph. Since this bike goes to see motion within the WorldTour, it is protected to imagine professional riders spend loads of time at speeds like this on their TT bikes. Ridley then took these designs to its Bike Valley wind tunnel and innovation hub the place time was spent refining the bike and its aerodynamics. Ridley claims a stiff and well-handling bike was additionally a precedence, the stiff carbon fibre body is claimed to assist with energy switch while making a secure platform to maximise efficiency.
Ridley declare lowering the bike’s frontal space has additionally been a key consideration. The Dean Quick body employs a small head tube which makes use of an hourglass determine form to assist form the airflow passing over it and lowering the general frontal floor. The stem can be aligned with the highest tube (pictured beneath) additional lowering the frontal floor space.
The ultimate aerodynamic characteristic of the Dean is what Ridley calls F-Floor Plus know-how which is once more, stated to optimise aerodynamic efficiency and already options on the Noah Quick Disc street bike. It takes the type of a textured floor and strategically positioned grooves on the body which purpose to minimise turbulence and cut back drag. These options are stated to ship extra of a bonus in stronger winds.
Tech specs and body particulars
Ridley will provide Dean framesets in small, medium and huge body sizes which can accommodate digital groupsets solely. There can even be a body and fork set choice accessible with a base bar solely to permit riders to make use of their most well-liked time trial bar extensions.
The body has been designed round 28mm tyres however can accommodate as much as a 32mm tyre on the rear.
A UDH (common derailleur hanger) has been specified in addition to a detachable entrance derailleur mount ought to riders select a 1x setup. There are additionally two f.d clamp choices, one to accommodate a 53-40T chainset and one other for a bigger 47-60T setup.
A dimension medium body is claimed to weigh 1250 grams, while the fork suggestions the scales at 460 grams and the time trial base bar 341 grams. The body additionally makes use of a PF30 backside bracket normal
There are additionally two bottle cage mounting positions on the body down tube. There’s a ‘coaching’ place which is larger up and inside simple attain for riders. In addition to an optimum racing bottle place which sees the bottle cage sitting in its lowest place for a quicker configuration.
We do not have data on Dean FAST pricing or construct configurations at the moment however you’ll be able to head to ridley-bikes.com for extra data.
