When it comes to weight weenie wheelsets they don’t come much lighter than these EVO 23T from FSE (Filament Spin Evolution).
The 25mm deep, 23.64mm wide rims are built to Extralite’s Cyber SP 20/24 hubs and Sapim CX-Ray spokes.
On the BikeRadar Scales of Truth these wheels come in at 494g for the rear and 393g for the front.
As you can imagine with wheels as light as these, FSE does note that these Extralight hubbed versions should be kept for events and race days only — hard daily training isn’t recommended. They come with a 180 lbs / 81kg rider weight limit too.
These wheels are destined for the UK hill climb 2018 race season.
If you’re looking for super-light wheels without this caveat, FSE also offers builds of its slightly wider 25T rims with DT Swiss 240S or its own 260SL hubs.
The EVO 23T Extralite’s are available direct from FSE for $1,895 or through dealers located worldwide.
