Ridley’s manufacturing unit staff racers have been torn between choosing the lightest, probably the most aero, or the gravel bike with the widest tire clearance, so the Belgian Biking Manufacturing unit gave them one to do all of it – the all-new Ridley Astr RS gravel race bike. At first look, it doesn’t look all that totally different from the opposite bikes within the Ridley gravel household. However, by combining race-ready aerodynamics in a lighter body with clearance for as much as 52mm tires, this new Astr RS simply turned the right alternative for anybody trying to go quicker off-road.
Ridley Astr RS light-weight aero carbon gravel race bike
Ridley already had a bunch of gravel bikes of their lineup – the full-aero Kanzo Quick, the bikepacking-ready Kanzo Journey, and the sunshine gravel Grifn… with reasonably priced alloy variations of these couple, too. They’ve been constructing gravel bikes since 2015/2016, and even evolving one of these mixed-surface driving & racing on cyclocross bikes for the reason that model debuted in 2000. So why did they want an all-new gravel race bike?
Nicely, it appears gravel racing retains getting gnarlier. And the professional riders on the Categorized Ridley Manufacturing unit Workforce merely demanded fatter tires to tackle these rougher programs. They already had a Kanzo Adv, however they needed aerodynamics on par with the Kanzo Quick. So it seems like what Ridley truly did was the identical factor that made their newest Grifn RS light-gravel all-road race bike. They mashed up the sunshine & modern options of their Falcn RS aero highway bike. And gave it the mega tire clearance of the Adv.
In the long run, this new Astr combines these quickest and most versatile options to create one new top-tier gravel race bike.
What’s new?
What actually units this new Astr RS aside are three options. Light-weight, aerodynamics, and large tire clearance.
Gentle comes all the way down to a top-tier ultralight carbon layup that is available in at a claimed 890g for the medium Astr RS body. That’s a whopping claimed 369g financial savings over the Kanzo Quick!
Aerodynamics is tailored from Ridley highway race bikes with aero tube sections all through, a large fork crown that transitions into wind diffuser fins on the downtube, dropped seatstays, an aero seatpost, and a rear wheel cutout.
The largest deal most likely although is the mega tire clearance on the brand new Astr. Ridley says there may be room for as much as 52mm tires with a single chainring setup, or as much as 47mm with a 2x crank and area for the entrance derailleur cage.
Gravel Race Geometry
Fats tires apparently don’t need to imply gradual dealing with geometry.
Combining massive tires, 2x, and aerodynamics was the true trick to maintain the race-ready dealing with really feel. Ridley managed to maintain the identical brief 425mm chainstays because the Kanzo Quick, in addition to the identical 71.5° headtube angle. Plus, there’s the steeper 74° seat tube and barely decrease backside bracket inherited from the Adv to compensate for the taller experience top of the bigger quantity tires.
Weight stability is a shade increased than the Quick – +3.5-5mm for taller tires, then -2mm from the additional BB drop. However Ridley additionally shortened headtube heights and managed to convey body Stack down a bit for a bit extra weight on the entrance wheel and a extra aerodynamic place on the bike.
