VITTORIA - 29" SYERRA
Syerra is the choice of aggressive riders who seek backcountry performance and dependability, in a sensibly lightweight package that punches well above its weight.
Designed for the most demanding XC courses, as well as for all-day adventures, climbing over mountain passes, and descending technical terrain, the Syerra is Vittoria’s best match for the increasingly popular Down-Country mountain bike segment.
- Tread design combines the grip of the Trail category with the speed of the XC category
- Fast rolling center tread, designed for capable climbing and confident braking
- Capable and well spaced side tread, holds your line on a range of terrain
- 4C Graphene compound system provides grip speed and durability
- Specifically designed Nylon casing construction with extra protection ensured by the Anti Pinch Flat insert (APF)
Syerra’s tread profile shares design-DNA of both Agarro and Mazza, but with reduced weight and improved rolling performance. The pronounced shoulders and a defined side-channel provide assured cornering bite and early engagement, allowing the progressive sipe-width to hold off-camber lines with ease.
Generous spacing combines with strategically placed tread surface siping, allowing the Syerra to scramble up loose rock faces, and self-clean on the next revolution. These sipes are built into Vittoria’s step-ramp tread blocks, allowing the tyre to maintain speed, while still providing a sharp effective edge for climbing and braking. This combination of traits keeps you tracking straight on loose over hard terrain, while retaining a category-defining level of tactile feel when things get slick.
Syerra is designed to be used front and rear, but also pairs well with other tyres. By using a durable Tubeless Ready casing, supported with Anti Pinch Flat APF sidewall inserts, the Syerra is much more robust and durable than the classic XC tyre you are used to with little effect on weight.
The end result is a quiver-killer tyre, that climbs as well as it descends. For those who earn their turns.

Down-Country [Tubeless TLR]
Down-Country casing is the ultimate casing construction specifically developed for the new Down-country segment. It combines the performance of a Vittoria XC casing with Trail technologies, for capable climbing and confident braking. The 60 TPI nylon casing provides durability and bouncing reliability, while the nylon layer below the tread guarantees dependable puncture protection. In addition, the anti-pinchflat rubber inserts increase both the sidewall and lateral defense protection.
Down-Country tyre uses a 4-compounds (4C) tread powered by graphene and combines two fast-rolling center tread compounds derived from XC with two grippy-side compounds derived from Trail.
Anti-pinchflat inserts [APF]
Down-Country tyres use rubber inserts placed over the beads. The anti-pinchflat inserts [APF] not only prevent the likelihood of pinchflats but they also favour the stability of the tyre and the overall protection of the tyre on the sides. The APF inserts are made in rubber to better sustain the tyre sidewall.
Vittoria 4C compound layering technology features separate base and surface compounds, in both the center and the side areas of the tread. This approach allows to fine-tune the flex of the tread-base and tread-surface separately, placing the correct hardness of the Graphene 2.0 compound exactly where it is needed for maximum cornering, climbing, rolling, and braking performance. In addition, durability and puncture protection are also improved, as the robust base compound resists punctures, and provides a stable base for deeper mountain bike treads. Each of the 4 layers is comprised of different natural and synthetic rubber types, blended into the compound that works best for the intended use. This allows for endless customizations of each layer according to the tyre needs.
