The Metron 45 SL Disc is the all-rounder of Vision's Metron range. It is light enough for long climbs and tough enough for gravel and cyclocross, and Vision's pro teams have raced it from the spring classics to mountain stages.

Highlights

• Full carbon 45 mm deep, tubeless-ready clincher rims with a 21 mm inner width
• Power Ratchet System (PRS) hubs with a 72-tooth helical clutch ratchet for 5° engagement
• 2:1 aero bladed direct-pull spokes, 21 front and 24 rear
• Centerlock rotor mounts and thru-axle end caps
• Built entirely by hand, with ABS self-locking nipples

One wheelset for most rides

Vision developed the rim with CFD analysis and wind tunnel testing, and its pro teams race the Metron 45 and 60 SL Disc on 28 mm tyres. The PRS ratchet engages 24% faster than Vision's previous 6-pawl hub and is built to last under load. Vision lists the pair at 1,490 g.

In the box

TA12 and TA15 front end caps, an X12 rear end cap, a tubeless kit, inner lockrings, a spoke protector and a wheelset bag.

Compatibility & fit

Disc brake only, for Centerlock rotors. The front takes a 12 mm or 15 mm thru-axle with the caps supplied, and the rear is X12 (12 mm thru-axle). This listing is the SRAM XDR freehub version, for SRAM XDR 12-speed cassettes. Our workshop can fit your tyres, set them up tubeless and move your cassette and rotors across.
