Swiss Aspect is not any stranger to optimized aerodynamics, and now claims their new Gravon Carbon 500 to be the quickest gravel bike wheels. However in actuality, that sounds extra like an announcement that they’re Swiss Aspect’s most aero gravel wheels but. And their actual promoting level is a steadiness of pace with relative affordability in comparison with a few of the extravagant huge title wheel launches..
Swiss Aspect Gravon Carbon 500 aero gravel wheels get sooner
It was solely two years in the past that Swiss Aspect first launched us to their Gravon aero gravel wheels, co-developed with DT Swiss. They usually mixed their transfer into gravel bike aerodynamics with a wealth of information exhibiting the Schwalbe G-One Velocity to be the most aero gravel tire of their wind tunnel testing. Within the meantime, DT Swiss utterly revamped their aero gravel GRC lineup with a sooner, lighter, and dearer 50mm deep wheelset – developed in CFD and confirmed within the wind tunnel with Swiss Aspect experience.
And as soon as once more, it seems to be like Swiss Aspect has leveraged that DT collaboration to adapt the identical new rim form with a extra inexpensive carbon layup and extra typical hubs & spokes to economize whereas nonetheless going quick.
The result’s the brand new Swiss Aspect Gravon Carbon 500, described as “essentially the most aerodynamic gravel wheelset designed for quick and environment friendly gravel rides“.
Sooner within the wind tunnel, however actually not by a lot
So, how briskly are the brand new Swiss Aspect Gravon Carbon 500 wheels actually? Fortunately, Swiss Aspect’s specialty is geeking out within the wind tunnel, so we’ve obtained loads of graphs and comparisons to see how they declare to have shaved off watts to make you quicker. And with attention-grabbing outcomes that oddly counsel that the aero gravel features may not be all they’re cracked as much as be!
Swiss Aspect put the brand new 50mm deep aero gravel wheels face to face with the 42mm deep wheels that these substitute, and their low-cost 25mm deep alloy wheels that carry over.
All fitted with 40mm benchmark Schwalbe G-One tires in a Cervelo Aspero at an inexpensive 30kph, the brand new Gravon Carbon 500 save a claimed 8% vs. the prior 420, getting most profit when the wind is available in at an angle as a consequence of good ‘crusing impact’. However that appears to solely save a couple of single watt within the bike. The features greater than double at 45kph, however they nonetheless should not big.
Perhaps most attention-grabbing to me is that the aero variations between the 25mm, 42mm & 50mm deep wheels are primarily the identical because the aero variations between 35mm, 40mm & 45mm tires. The narrower tire was sooner on each shallow & deep rims with the 40mm lower than a watt slower at cheap beginner gravel rider speeds.
Tech particulars
The massive change within the new Swiss Aspect Gravon Carbon 500 wheelset is the brand new rim. It’s 24mm hooked tubeless inside, with a max outer width of 36.5mm x 50mm deep total. They don’t say it explicitly, however the dimensions and distinctive form that tapers sharply from the widest level again to the bead counsel that is the very same profile on the brand new DT GRC 50 rim.
Swiss Aspect builds the brand new Gravon Carbon 500 wheels with a medium flange centerlock DT Swiss 370 hub which means a Ratchet LN freehub with a 36T ratchet. They usually lace them with 24 j-bend DT Aero Comp bladed spokes with alloy Professional Lock inner nipples.
At 1746g (797g entrance/949g rear, claimed), the wheels are heavier however extra inexpensive than the DT analogues – greater than 900€ lower than the 1100 or 450€ than the 1400 degree.
