New 451 Tyre by Schwalbe - Ultremo ZX (Folding 160g)


Size: ETRTO 23-451 (451 x 23C Inch)
Compound: RaceStar
Execution: Evolution Line

, HD Speed Guard

Color: Black-Skin

Weight: 160 g (6 oz)
Pressure: 100-160 psi (7,0-11,0 Bar)
Maximum load:
Tread: HS 380
EPI: 127

Faster and even faster. We challenge ourselves. That is why in the "ZX" we installed our latest developments, RaceStar Triple Compound and HD-Speed-Guard. Both components perfectly combine the requirements of competition racing cycle tires. That is exactly why the ZX is the best Ultremo ever!

The question is: On what rim will they fit?

Some samples on their way! Will post if they fit on my AlexRim30

The Ultremo ZX is narrower than the Durano.

Will update when they arrive.
