1 Stem, 2 handlebar diameters. The Black One D-2 stem builds on the success of our flagship Black One Enduro stem and brings in the ability to run both Ø31.8mm and Ø35mm handlebars with one stem.
The special designed shim allows the use of Ø31.8mm bars and when removed, it works as an Ø35mm stem. The shim provides a wide, smooth clamping area which is ideal for use with carbon bars.

The intelligent no-gap clamping design in the bottom ensure no pinch points, and equal clamping force for safety and stability. Because the most loads and notching effects are always at the bottom of the handlebar. And our smooth no-gap surface enlarges the lifetime of your handlebars.

The Black One D-2 is ideal for riders who have a few sets of Ø31.8mm/35mm bars with different rises and want to continue using them all, or who may want to upgrade to a 35mm bar in the future, without having to buy another stem. Available in 35mm lengths in Black matt finishes.

We also offer an extra light Black One D-2 TITANIUM version of this stem with understated Black or Polished finishes, with full Titanium bolts.

Designed from EWS riders inputs
The new Vittoria Mazza combines years of athlete input with cutting edge tread technology, raising the bar on the mixed terrain Enduro tyre category Starting with a defined center tread, the Mazza uses deep siping in the direction of rotation, allowing the tyre to roll fast while still opposing drift, especially in off-camber terrain The stepped leading edge rolls like a ramp, but digs in on climbs, making Mazza a top choice for both front and rear use Substantial room was designed into the center tread to provide braking traction, while also accelerating cleaning Cornering on the Mazza is handled by Vittoria’s trademark progressive sipe width technology, which gives a gummy inside effective edge, but without the instability that competitors experience on the outside of the tread Simply put, bigger sipes flex more than smaller sipes This unique siping pattern creates asymmetrical tread flex, and translates into a predictable, confident, and communicative feel at the limit of cornering Mazza’s generous tread depth claws into a range of terrain, and is stabilized with Vittoria’s proprietary 4C compound layering process Four separate Graphene 20 compounds are layered, allowing the surface of the tread to remain tacky, while the base remains planted This ensures each effective edge is kept in place under high cornering and braking loads, leading to reduced rolling resistance, and increased wear life The bar has been raised
