Parcours’ updated Chrono wheels debut three new selections from deep, to deeper, to full disc for riders looking out for further velocity with out giving up crosswind stability.
The model new Chrono wheelset is a blended depth entrance and rear combo. They’re joined by the deeper Chrono Max entrance wheel, which may very well be paired with the all-new Chrono Disc² rear wheel. No matter being deeper than their predecessors, they windtunnel examined to be merely as safe nevertheless now sooner in a straight line.
They’re moreover designed and aerodynamically optimized for 28mm tubeless tires, giving riders some nice advantages of lower air pressures, larger traction and further comfort with out shedding velocity.
Parcours Chrono Wheelset
Designed in collaboration with Nottingham Trent Faculty and Dr. Steve Faulkner, the model new fluctuate is constructed on their #thinkwider thought (study the white paper proper right here). The target is to produce the quickest attainable wheels that may also maintain safe, predictable coping with in crosswinds.
The TL;DR mannequin is that they found that precise world yaw angles differ by as a lot as 1.5º from entrance to rear, so the rim profiles are completely completely different for front and back. A blunter U-shaped entrance rim profile handles steeper wind angles larger, whereas a V-shaped rear rim slices by the air larger on the lower yaw angles it sees.
The Chrono Wheelset makes use of a 68.6mm deep entrance wheel with a 75.7mm deep rear wheel. It’s the deepest combo they supply, aimed towards racers, triathletes and time trialists who don’t want to go full disc throughout the rear.
The model new, wider design has a 17% enchancment in crosswind stability over the prior design, nevertheless is solely as aerodynamic. They’re saying it handles as correctly or larger than many rivals’ shallower aero wheels.
They measure 22.5mm inside with a most exterior width of 32mm (entrance) and 30.5mm (rear). Claimed weight is 1620g (745g entrance, 875g rear), laced 24/24 with Sapim CX-Ray spokes. MSRP is $1,599 (€1,559 / £1,199) for the set with EZO metallic bearings, or enhance to Kogel Ceramic for numerous hundred bucks further.
Parcours Chrono Max and Disc wheels
The Chrono Max goes a bit deeper for as of late when you want to pair with a full disc rear. It measures 83.6mm deep, 22.5mm huge internally, and 32mm huge externally. Claimed weight is 805g laced 24/24 with Sapim CX-Ray spokes. All wheels use a Centerlock disc brake rotor mount.
They’re saying the Chrono Max saves 4 watts as compared with the prior 77mm deep wheel, nevertheless handles with the an identical stability. MSRP is $800 (€780 / £600) by itself.
The Chrono Disc² claims to be the first full disc rear wheel completely optimized for wider tires, working with as a lot as 700x30mm tires with no aerodynamic penalty. It’s 120g lighter than their prior disc wheel, coming in at a claimed 1,240g and measuring 22.5mm inside/30.5mm exterior.
MSRP is $1,399 (€1,359 / £1,049) alone, or bundle it with the Chrono ($2,119/€2,049/£1,599 for the set) or Chrono Max ($2,199/€2,139/£1,649 for the set) entrance wheels. All fashions accessible now.
